Free AI video generator: one prompt, one finished video

Describe the video you want in a sentence or two. The AI writes the script, records the voiceover, generates a visual for every scene, adds word-by-word captions and renders an MP4 you can post. No camera, no editing timeline, no stock-footage hunting.

Describe your video

Write the idea, pick a format, and the creator builds the full video.

Mariana Trench documentary short

An existing English documentary example showing narration, deep-sea illustrations, and captions together. Use it to compare pacing and visual structure before planning your own video.

  • A clear question introduces the subject
  • Deep-sea visuals accompany the narration
  • On-screen captions follow the spoken words

Tool details

From prompt to video in three steps
  1. 01

    Describe the idea

    Write the topic, the angle and the tone. A specific prompt such as 'three mistakes beginners make with sourdough' beats a vague one like 'bread'.

  2. 02

    Choose short or long

    Vertical 9:16 for TikTok, Reels and Shorts, or widescreen 16:9 for YouTube. You can adjust voice, style and length in the creator before generating.

  3. 03

    Generate and download

    The AI writes, narrates, illustrates and captions the video. Watch it, then download the MP4 and publish it wherever you like.

About this tool

What the AI video generator actually makes

A complete video, not a clip to finish elsewhere. Your prompt becomes a script with a hook in the first seconds, the script is read by an AI narrator, every scene gets a generated image or animated shot that matches what is being said, and captions highlight each word as it is spoken. The output is a rendered MP4 in the format you chose.

Formats you can generate

Beyond a classic narrated explainer, the creator has dedicated formats: stickman stories, kids rhymes, talking objects, character videos with a recurring cast, Reddit-style story videos and documentary shorts. Pick the visual style that fits the channel, from cinematic and realistic to anime, 3D cartoon, comic book or claymation.

Free plan, honestly explained

The free plan gives you a free video every day. Free videos are up to 90 seconds, render at 720p, use still-image scenes and carry a small FacelessGenie watermark. Paid plans remove the watermark, render at 1080p, unlock long-form videos and premium voices and models, and let you generate more videos each month.

How an AI video generator differs from a video editor

A video editor assumes you already have footage, a voice track and a plan. An AI video generator starts one step earlier: it writes the plan for you. The script is structured for retention with a hook, a sequence of beats and a payoff, and every beat gets its own generated visual. Instead of dragging clips onto a timeline, you judge a finished draft and regenerate what you do not like.

Making faceless videos for YouTube, TikTok and Reels

Faceless channels publish without anyone appearing on camera, which makes them a natural fit for generated video. Explainers, history stories, science facts, finance basics, motivational shorts and kids content all work as narration over visuals. The useful habit is to plan a series rather than one-off uploads: a recognisable format, a consistent voice and a posting rhythm make a channel easier to grow than a pile of unrelated videos.

Getting better results from your prompt

The AI does more with specifics. Name the audience, the length and the single takeaway, and mention any facts or numbers that must appear. If you want a particular structure, such as a top-five list or a story with a twist at the end, say so. When a draft misses, change one thing in the prompt at a time so you can see what moved the result.

Frequently asked questions

Is the AI video generator really free?

Yes, there is a free plan with a free video every day. Free videos run up to 90 seconds at 720p with a small watermark. Paid plans remove the watermark and add more videos, higher resolution and long-form.

Do I need to sign up?

You can write your prompt without an account, but generating a video needs a free account so the finished file can be saved to your library. Signing up takes an email address or a Google account.

Can I make videos in languages other than English?

Yes. Write the prompt in your language and the script, voiceover and captions follow it. More than 30 languages are supported, including Spanish, Portuguese, German, French, Italian, Polish and Hindi.

How long can a generated video be?

Free videos are up to 90 seconds, which fits Shorts, Reels and TikTok. On paid plans you can generate long-form 16:9 videos for YouTube that run for many minutes, up to 20 minutes on the higher plans.

Can I monetize videos made with the generator?

Paid plans include commercial rights, so you can publish the videos on monetized channels. Platforms reward original, useful content, so give each video its own idea and angle rather than mass-producing near-identical uploads.

What makes a good prompt?

One clear topic, the audience, the tone and the ending you want. 'Explain compound interest to teenagers in 45 seconds, friendly tone, end with a one-line takeaway' gives the AI everything it needs to write a tight script.
