Explainer Video Generator: one-sentence prompt to narrated MP4 with SRT subtitles

Explainer Video Generator turns one sentence into a finished animated explainer video. You describe what you want to explain, and an AI director writes the script, records the narration, draws every scene and adds a music score, then delivers an MP4 together with SRT subtitles and a cover image.

It is aimed at founders, marketers, teachers and content teams who need short explainers without hiring an animator or learning video software. Common jobs include product launch videos, data stories, how-it-works walkthroughs and educational explainers for social channels or landing pages.

You can steer the result in several ways: add up to ten must-say points, upload your logo, images, screenshots or a PDF to ground the script, and choose one of eight narrator voices in English or Chinese. Visual looks include whiteboard, blueprint, data story, isometric infographic and dark keynote styles. You also pick the audience (everyone, children or parents), the format (landscape 16:9 or vertical 9:16) and a length between fifteen and sixty seconds.

A film usually takes about thirty to fifty minutes to render, and credits are refunded automatically if a film fails. Pricing is paid only: Starter costs $19 per month, Pro costs $49 per month, and there is a one-time pack of 900 credits for $29. Each started ten seconds of video uses 100 credits.

A typical session looks like this. Write one sentence that states what the viewer should understand, list the points that must be mentioned, and attach any material the script should rely on, such as a product screenshot or a short PDF. Pick a narrator voice, a visual style, the audience and the aspect ratio, then start the render and come back later for the finished MP4. Because the subtitles arrive as a separate SRT file, you can upload them to YouTube or edit them before posting. The cover image is ready for a thumbnail or a landing page hero. Teams that publish often use the vertical format for short social clips and the landscape format for websites and presentations, so one idea can become two finished videos with very little extra work.
