About VibeKnow

Free AI video generator that turns documents, PDFs, PPT, and URLs into polished videos with voiceover and visuals, for explainers, demos, and training. We handle the full production stack, not just one piece. You stay in the parts that need your taste; we handle the rest. It writes the script first, then builds every visual around the story. You shouldn't also have to learn Premiere, hire a voice actor, design title cards, color-grade, and re-export six aspect ratios, just to publish what you already finished.

About WebMotion

Compose video in the DOM, encode it with WebCodecs, download an MP4. No FFmpeg, no headless Chrome, no render farm. Every frame is a pure function of the frame index. The frame number is drawn by the scene, so scrubbing anywhere keeps it honest. Everything visible is a pure function of the current frame. Give the renderer a frame index and it draws exactly one image. Seeking is exact because there is no state to wind forward.
