Not so long ago, creating a professional video required a camera, a microphone, suitable lighting, editing software and at least basic technical knowledge. Today a large part of this work can be taken over by AI video generators, which can prepare a finished video from a short prompt, a script, an article or a website address. Artificial intelligence can write a script, select shots, generate narration, create subtitles, match music and prepare a video in a format suitable for YouTube, TikTok, Instagram or a company website.
This does not mean, however, that every tool works in the same way. Some platforms specialise in realistic AI avatars, others create complete videos from a single prompt, and still others work best at turning articles, offers and product pages into short promotional materials. That is why the choice of the best AI video generator should depend above all on what kind of video we want to create and where we intend to publish it.
In our ranking we compare five tools that respond to the different needs of creators, marketers, online stores and business owners. They are HeyGen, InVideo AI, Synthesia, Pictory and RenderLion. Each of them can be tested before you decide to buy a paid plan.
What is an AI video generator?
An AI video generator is a tool that uses artificial intelligence models to automatically create or edit video materials. The user can type in a topic, paste a script, upload photos, add a link to an article or point to a product page, and the system will prepare a video on that basis. Depending on the chosen platform, the material may contain generated images and shots, stock footage, an avatar speaking to the camera, an AI voice-over, music, subtitles and animated graphic elements.
The biggest advantage of such solutions is that they reduce the number of production stages. Traditionally, the script, voice recording, selection of materials, editing and adding subtitles were done separately. An AI video generator can combine these activities into a single process that starts with typing in a prompt and ends with exporting the finished video.
Tools of this type are not used only for creating short, experimental clips. Increasingly they are used to make advertising videos, training materials, product presentations, tutorials, YouTube content, UGC ads, online courses and videos intended for internal company communication. The right software can therefore significantly reduce the costs and time needed to publish video content regularly.
The best AI video generators in 2026 – a quick comparison
The table below shows the most important differences between the compared tools. The ranking does not point to one program that is ideal for everyone. HeyGen and Synthesia are particularly strong in videos with digital presenters, InVideo AI makes it possible to prepare a complete video from a prompt, Pictory works well for recycling existing materials, and RenderLion lets you quickly turn content and websites into short animations.
| Tool | Best use | AI avatars | Video from text | Article or link to video | Free trial |
|---|---|---|---|---|---|
| HeyGen | Videos with avatars, ads, presentations and video translation | Yes | Yes | Partially | Yes |
| InVideo AI | Complete videos from a single text prompt | Yes | Yes | Yes | Yes |
| Synthesia | Training, onboarding, presentations and company communication | Yes | Yes | Partially | Yes |
| Pictory | Turning articles, scripts and presentations into videos | In development | Yes | Yes | Yes |
| RenderLion | Short animations, product videos and social media content | No | Yes | Yes | Yes |
The most versatile tool for people interested in avatars and marketing materials is currently the HeyGen AI video generator. For creating complete videos from a short description, InVideo AI for generating videos from text remains a very interesting option. Companies that need professional training materials, on the other hand, should check out the Synthesia platform with AI avatars.
How was the AI video generator ranking created?
When comparing the tools, we took into account above all their usefulness in real marketing work. A visual effect alone is not enough if preparing a video requires many corrections, additional programs or manually assembling all the elements. A good generator should not only create attractive shots, but also help prepare the script, narration, subtitles and a suitable structure for the material.
The ability to create different types of videos also mattered. Different features are needed when producing an online course, different when preparing a product ad, and still different when running a YouTube channel without showing your face. We therefore paid attention to versatility, avatar quality, ease of editing, supported formats, the ability to work in Polish and the availability of a free plan or trial version.
It is worth remembering that AI generators are developing extremely quickly. The features available in individual packages and the rules for calculating limits may change. Before buying a subscription, it is best to first test the tool on your own scenario and check whether the resulting video style suits the character of the brand.
HeyGen – the best generator of videos with AI avatars
HeyGen is one of the best-known video generators using realistic avatars. The user can choose a ready-made character, create their own avatar or prepare a video based on a photo and text. The platform generates speech, synchronises lip movement with the recording and lets you create videos in many language versions.
The tool works well for materials in which you need a person speaking directly to the viewer. These can be offer presentations, sales videos, instructions, lessons, educational content, UGC-style ads and messages published on social media. Instead of organising a recording every time, you can prepare a script and generate the next statement from a digital presenter.
HeyGen is also developing features related to creating whole videos. The platform can combine avatars, narration, additional materials and generated shots, so it is no longer limited to a static figure standing against the background of a slide. This is an important change for marketers who need more dynamic advertising content.
Who will HeyGen be the best choice for?
HeyGen is worth considering when a company regularly publishes materials featuring a person speaking to the camera, but does not want to organise many recording sessions. The tool can be useful for experts, trainers, course creators, marketing agencies, online stores and companies selling services. It works especially well where the ability to quickly prepare several versions of the same statement matters.
The platform can also make expansion into foreign markets easier. Instead of re-recording the entire material, you can prepare a version in another language. Artificial intelligence matches the voice and lip movement, which makes it possible to achieve a much more natural effect than with a traditional voice-over laid over the original recording.
You can create your first material using HeyGen for generating videos with an AI avatar. The free plan lets you check the platform’s basic capabilities before moving to a subscription.
The most important advantages and limitations of HeyGen
HeyGen’s biggest advantages include realistic avatars, lip-sync, the ability to create your own digital character and a wide range of marketing uses. The interface is relatively simple, so preparing your first video does not require experience in traditional editing.
A limitation may be the cost of more advanced features and the number of credits needed to generate longer materials. The result also depends on the quality of the script. Even the best avatar won’t save a text that sounds artificial, is too formal or hasn’t been adapted to speech. That is why, before generating a video, it is worth reading the script aloud and simplifying sentences that are too long.
InVideo AI – the best generator of a complete video from a single prompt
InVideo AI is intended for people who want to go from an idea to a finished video without manually preparing every element. The user describes the topic, the audience, the desired length, the style and the publishing platform. The tool can then write the script, select shots, prepare a voice-over, music and subtitles, and assemble all the elements into a single piece.
A big advantage of InVideo AI is the ability to edit the video using text commands. Instead of looking for a specific fragment on the timeline, you can ask the system to change the intro, remove a scene, add subtitles, shorten the video or apply a different voice. This approach is much more accessible for people who don’t know classic editing programs.
The platform works well, among other things, for running faceless YouTube channels, preparing tutorials, popular-science videos, service presentations and short informational materials. It can also be used to quickly test many content ideas.
Who will InVideo AI be best for?
InVideo AI is a good choice for creators who don’t want to record materials themselves or spend many hours on editing. The tool can prepare the first version of a video practically from start to finish, which is why it works particularly well for the regular production of content for YouTube and social media.
Business owners and marketing specialists can also use the platform. Based on a description of a service, a product or a customer’s problem, you can prepare an educational or promotional video. The finished material is still worth reviewing and correcting, but the number of tasks performed manually is much smaller than in traditional production.
You can start creating in InVideo AI for automatic video generation. Before choosing a paid package, it is best to generate a short test piece and check how many credits the chosen production method uses.
The most important advantages and limitations of InVideo AI
The most important advantage is its comprehensiveness. The tool doesn’t expect the user to have a finished video to edit, but can help right from the idea and script stage. InVideo AI gives access to different kinds of materials, voices and generative models, which lets you experiment with style without using several separate platforms.
The automatic selection of shots won’t always be perfect, however. With specialist topics, artificial intelligence may choose visuals that are too general or don’t fit the context. The finished video should therefore be treated as a strong draft, not as material that can always be published without checking.
Synthesia – the best AI video generator for businesses and training
Synthesia focuses on professional videos created for business. The platform uses AI avatars, which can present training content, instructions, presentations, procedures and onboarding materials. Instead of recording an employee or an actor, a company can prepare a script, choose a presenter and generate the material in the appropriate language.
The tool is particularly useful in organisations that frequently update educational materials. Changing a single procedure doesn’t have to mean organising a new recording. It is enough to correct a fragment of the text and generate a new version of the video. This makes it easier to maintain consistent training materials across many departments and language versions.
Synthesia also offers features useful for teamwork, creating materials consistent with visual identity and turning presentations into videos. The platform has a more corporate character than some of the tools geared towards dynamic content for TikTok or UGC ads.
Who will Synthesia be the best choice for?
Synthesia should interest, above all, companies, HR departments, sales departments, course creators and organisations that run internal training. The platform is well suited to creating materials in which clarity, repeatability and the ability to update quickly matter most.
This doesn’t mean you can’t create marketing content in it. Its strongest side, however, remains professional presentations and videos with a presenter, rather than very dynamic ads intended for short social formats.
You can check the platform’s capabilities through Synthesia for creating business videos with AI avatars. The free version lets you assess the presenter’s quality and language support before choosing an extended plan.
The most important advantages and limitations of Synthesia
Synthesia’s biggest advantage is the professional character of its materials and its extensive features designed for businesses. The tool makes it easier to prepare training in many languages, update content and maintain a consistent communication style.
For creators focused on quick, emotional sales materials, the platform may seem too formal. In that case, HeyGen or InVideo AI may be a better choice. Synthesia shows its full potential above all when the material is meant to convey knowledge, present a procedure or guide the viewer through a specific process.
Pictory – the best tool for turning text and articles into videos
Pictory is particularly interesting for companies and creators who already have a large base of text materials. The platform can transform articles, scripts, presentations, recordings and website addresses into videos containing shots, narration, music and subtitles. This way an existing blog post doesn’t have to end its life after being published in Google.
For example, a comprehensive guide can be turned into a YouTube video, several shorter pieces for social media and a presentation of the most important conclusions. This kind of content recycling increases the value of material that has already been developed and lets you reach people who prefer video to text.
Pictory can also help shorten longer recordings and pick out the most important fragments. This is useful for podcasters, trainers, webinars and companies that publish extensive educational materials.
Who will Pictory be the best choice for?
Pictory will work best for bloggers, experts, content marketing agencies, owners of topic-focused websites and companies that want to reuse existing content. If a website has several dozen valuable articles, they can become the basis of an entire series of videos without having to come up with topics from scratch.
The tool can also be a good solution for people who have a ready script but don’t want to look for materials themselves and arrange them on a timeline. Pictory analyses the text, divides it into scenes and suggests matching visuals.
You can prepare your first material using Pictory for turning text and articles into videos. It is worth starting the test with one of your most-visited blog posts and comparing how the tool interprets its structure.
The most important advantages and limitations of Pictory
Pictory’s main advantage is the ability to reuse content. The tool lets you relatively quickly transform a long text into a more accessible visual form. With regular blog publishing, it can become an important element of a content marketing strategy.
As with other automatic generators, the selection of visual materials may require corrections. Especially in technical or specialist texts, some shots may be too generic. It is therefore worth spending a few minutes replacing scenes that do not strengthen the message.
RenderLion – a simple generator of short videos and animations
RenderLion lets you turn text, images, posts, articles and website addresses into short animated videos. The tool is aimed primarily at marketers, online store owners, content creators and people who manage social media.
One of the more interesting uses is creating videos based on a product page. The user can provide the address, and the system analyses the content and prepares an animated piece presenting the most important elements of the offer. The video can then be used on Instagram, TikTok, Facebook, YouTube or in an advertising campaign.
RenderLion makes it possible to generate materials in vertical, square and horizontal formats. This way the same idea can be adapted to different channels without preparing the project from scratch.
Who will RenderLion be the best choice for?
RenderLion is an interesting option for small businesses, online stores and people who need simple, short promotional materials. It is not a direct competitor to advanced platforms with realistic avatars. Its strength is speed and the easy transformation of existing data into an animated form.
The tool can be used to present promotions, product news, blog posts, announcements, events and brand messages. A store owner doesn’t need to prepare an elaborate script. The starting point can be an existing product page or a short description of the offer.
You can check the program’s capabilities through RenderLion for creating short AI videos. The free plan that is available lets you generate test materials, although videos created free of charge may contain the platform’s branding.
The most important advantages and limitations of RenderLion
The most important advantages are simplicity, speed of operation and support for several publishing formats. RenderLion can be a good first tool for a company that wants to start creating video without investing in an elaborate system.
However, the platform doesn’t provide avatars as realistic as HeyGen and Synthesia, or such an extensive process for building complete videos as InVideo AI. It is best treated as a generator of short marketing animations, not a complete film studio.
Comparing AI video generators by use
Choosing the right tool becomes easier when we start from a specific goal. Instead of asking which generator is the best in every possible scenario, it is worth determining what type of material will be created most often.
| Need | Recommended tool | Why choose it? |
|---|---|---|
| A realistic avatar speaking to the camera | HeyGen | A good combination of avatars, translations and marketing materials |
| Training and internal communication | Synthesia | Professional business materials and easy content updates |
| A complete video from a single prompt | InVideo AI | Automatic creation of the script, shots, voice, music and subtitles |
| Turning an article into a video | Pictory | Extensive features for working with text, links and existing materials |
| Short animations for a store and social media | RenderLion | Quickly turning offers, products, texts and URLs into video |
| A YouTube channel without showing your face | InVideo AI or Pictory | Automatic production of narration and illustrative materials |
| A multilingual presentation with a presenter | HeyGen or Synthesia | Avatars, translations and generating different language versions |
Which AI video generator to choose for a business?
For most small businesses, the best starting point will be HeyGen or InVideo AI. HeyGen will work when the videos are to feature a speaking character, whereas InVideo AI will be better when the material should consist of many shots, narration, music and subtitles.
Companies that run training for employees or customers should take a closer look at Synthesia. The platform was designed with repeatable business materials in mind, which have to be regularly updated and translated.
In e-commerce, RenderLion may be an interesting choice, especially if the main goal is to quickly create short product presentations and promotions. A store with an extensive blog can additionally use Pictory to turn shopping guides into videos.
Which AI video generator to choose for YouTube?
For a YouTube channel without showing your face, InVideo AI may be particularly useful. The tool helps you go through the entire process, from preparing the script to generating the narration, shots and subtitles. This lets you create first versions of longer videos relatively quickly.
Pictory will be a good solution for people who already have texts, recordings or presentations. Instead of creating the material from scratch, you can turn an existing blog post into a script and a video. HeyGen, in turn, can be used to add a host who introduces the topic or comments on individual parts of the material.
Whichever tool you use, automated production should not mean publishing random videos without quality control. YouTube rewards materials that solve a specific problem, hold attention and genuinely add value. AI speeds up production, but you still need a good topic, a clear point of view and a well-thought-out structure.
Which AI video generator to choose for TikTok, Reels and Shorts?
Short materials require a fast pace, a strong opening and a clear message. HeyGen can be used to create short avatar statements, UGC ads and educational videos. InVideo AI lets you prepare more dynamic materials made up of many shots, while RenderLion will work for simple animations, promotions and offer presentations.
Pictory can be used to shorten longer content and turn fragments of articles into short materials. The most important thing, however, is adapting the script to the format. A vertical video should not be merely a shortened version of a long material. It must start with a question, a surprising piece of information or a promise of a specific result.
Is there a completely free AI video generator?
Most popular platforms offer a free plan, a demo version or a limited number of credits. This lets you check the interface, the quality of the generated materials and the basic features. Free packages may, however, include a watermark and limit the resolution, the length of the video or the number of available exports.
For learning and first experiments, the free version is usually enough. With regular publishing, serving customers or commercial use, the need for higher quality, more minutes and the removal of the platform’s branding quickly arises. For this reason, it is not worth choosing a program solely on the basis of the lowest price.
The most sensible strategy is to test two or three tools on the same scenario. This way you can compare not only how the video looks, but also the time needed for corrections, the voice quality, how well the shots fit and the ease of export.
How to create a video with AI step by step?
Set one specific goal for the material
The first step should be to determine what the viewer is meant to do after watching the video. The material can educate, encourage a purchase, present a product, build trust or direct people to a website. Trying to achieve all of these goals at once usually leads to a chaotic script.
It is also worth specifying the audience, the publishing platform and the desired length. A video for an online store owner should look different from one aimed at a person hearing about a given product for the first time.
Prepare a script or a precise prompt
The more precise the prompt, the greater the chance of getting good material. Instead of typing “make a video about marketing”, it is better to describe the topic, the target group, the length, the tone, the structure and the desired call to action.
In a video script you should use shorter sentences than in an article. The text should sound natural when read aloud. It is worth avoiding long enumerations and complicated constructions, because even a realistic AI voice may then sound unnatural.
Choose the right type of video
If the material is to be based on a presenter’s statement, HeyGen or Synthesia will be a good choice. When you need a video made up of many scenes, it is worth trying InVideo AI. Pictory can be used to turn an article into a video, while a simple animation of a product or offer can be prepared in RenderLion.
There is no need to use one program for all types of content. In practice, companies often combine several tools, for example creating an avatar in HeyGen, generating additional shots in another system, and then preparing short versions of the material for social media.
Check the script, pronunciation and visual materials
Before exporting, you need to watch the video carefully. Pay attention to the pronunciation of proper names, numbers, abbreviations and industry terms. It is also worth checking whether the chosen shots really match the sentences being spoken.
Artificial intelligence can create a technically correct material that at the same time lacks coherence. Human oversight remains necessary, especially when the video represents a brand or contains product information.
Add a call to action
The video should end with clear information about what the viewer can do next. It could be visiting a website, signing up for a newsletter, downloading a resource, booking a consultation or checking out a product.
The call to action shouldn’t appear only at the very end. In longer materials you can naturally mention the next step in the middle of the video as well, especially if some viewers won’t reach the last scene.
What to look out for before choosing an AI video generator?
Quality of Polish language and voice
Not every tool handles Polish pronunciation equally well. Before buying, you should test surnames, brand names, numbers, English abbreviations and specialist terms. It is also important whether you can change the pace, the emotion and the way the speech is emphasised.
The ability to edit the video manually
Full automation sounds attractive, but in practice corrections are almost always needed. A good generator should allow you to replace a shot, change the text, correct the subtitles, choose a different voice and adjust the length of scenes.
Available formats and resolution
For YouTube you most often need the horizontal 16:9 format, while TikTok, Reels and Shorts use the vertical 9:16 format. For posts on some platforms, the square 1:1 format may also be useful.
It is worth checking whether the chosen plan allows export in the appropriate resolution and without a watermark. The free version may look good during testing, but it won’t always be suitable for materials published by a company.
Licence and the possibility of commercial use
Before using a video in an ad or in a client’s material, you should familiarise yourself with the platform’s licensing terms. What matters is not only the video itself, but also the music, voices, stock materials and elements generated by external models.
The terms of use of the tools may be updated, so you should not base your decision solely on information found in an old review. The most important source remains the current terms and conditions of the specific platform.
Will AI video generators replace video editors?
AI video generators can take over a significant share of repetitive tasks, but they do not eliminate the need for creative thinking. The tool can select shots, create a voice and add subtitles, but it does not always understand the brand’s context, the viewer’s emotions and the strategic goal of the campaign.
In simple informational materials, artificial intelligence can do most of the work. For large campaigns, image films and productions that require unique storytelling, a human is still needed to make artistic decisions and ensure consistency.
The best results are therefore achieved not by people who hand the whole process over to artificial intelligence, but by those who can use AI to speed up their own work.
Frequently asked questions about AI video generators
What is the best AI video generator?
The best generator depends on the type of material being created. HeyGen works well for videos with avatars, InVideo AI for complete videos from a prompt, Synthesia for business training, Pictory for turning text into video, and RenderLion for short product and social animations.
Can you create an AI video in Polish?
Yes, popular generators support Polish text and voices. The quality of pronunciation may, however, differ depending on the tool and the chosen voice. Before publishing, you need to check proper names, numbers, abbreviations and specialist vocabulary.
Can videos created by AI be published on YouTube?
AI-generated materials can be published on YouTube, as long as they comply with the platform’s terms and the licensing rules of the tool used. The mere fact of using AI does not replace the need to create valuable, original and reliable content.
Are editing skills needed to create an AI video?
Basic videos can be prepared without knowing traditional editing. The tools automatically arrange scenes and add narration, subtitles and music. The ability to assess the quality of the generated material and correct it is, however, still very useful.
How long does it take AI to generate a video?
A short piece can be created within a few minutes, but the time depends on the length, the type of shots generated, the chosen model and the platform’s load. You also have to factor in the time needed to check the video and make corrections.
The best AI video generator – ranking summary
There is no single AI video generator that will be the best for every use. HeyGen is a very good choice for people who need realistic avatars and marketing materials. InVideo AI will work well for creating complete videos from a single prompt. Synthesia is a strong option for companies, HR departments and training creators. Pictory lets you make use of existing articles, scripts and recordings, while RenderLion makes it easier to prepare short product animations and social media materials.
The best way to choose is to generate a similar material in several platforms. It is worth comparing the quality of the Polish voice, the selection of shots, the time needed for corrections and the final cost of production. This way the decision will result from real needs, not only from an impressive presentation on the manufacturer’s website.
For videos with a digital host, it is worth starting with a free trial of HeyGen. For creating whole materials from a prompt, you can use the InVideo AI video generator, and for professional presentations and training the Synthesia platform. People with an extensive blog can check out turning articles into videos in Pictory, while stores and small businesses can try short product videos in RenderLion.
