What is mind2D.ai?
An AI video generation service that turns your slides into videos with voice and subtitles
mind2D.ai is an AI video generation service that turns PowerPoint and PDF slides into narrated animated videos. The AI writes a script from your slide content and presenter notes. Review and edit it, then export a video with voice, subtitles, and a character.
Scripts written by AI can be reviewed for technical terms, figures, and content before you publish. It reduces the burden of filming, recording narration, and editing video, so your in-house documents can be put to work as video training material.

What makes mind2D.ai different
All you do is upload your file
Slides, audio and the character are synced automatically. The generated audio comes with text you can edit at any time.
AI writes the whole script
It understands your slides, sums up the key points and writes lines for every page — even handling scene changes and subtitle timing for you.
13 characters, 30 voices
Pick the character and background that fit your purpose. Each character comes with a matching voice, and you can swap it for any voice you like.
Highlights the line being read
As the narration reads a sentence, the matching text on the slide is automatically highlighted — so viewers always know where you are.
No video editing needed
Make it once and publish it as is. Even with no extra editing, you get a video that works as real training material.
Never used to train AI
The files you upload and the scripts you create are not used to train AI (opt-out).
