Narration, timed to the motion
Every scene ships with a matching narration track. ElevenLabs voices, synchronised with the pacing of each segment as it's composed.
Unlike · silent clips you have to caption or dub yourself.

How it works
Prompt in. Motion out.
01
Type your prompt
Describe what you want to explain. A concept, a process, a problem. PromptAnim parses intent into a plan.
02
We compose the scenes
Visuals, motion, narration, and pacing are generated in parallel. You watch progress stream in live.
03
Get a 1080p video
Download the MP4, share the link, or iterate on the prompt. Average finish time: under two minutes.
Why PromptAnim
Different from a video generator.
The generic AI video tools ship silent clips or stitched stock. We ship narrated concept-explainers, ready to publish.
1080p MP4 you can ship anywhere
Standard container. Drop it into YouTube, an LMS, a Notion embed, a slide, or a Loom. Full ownership, no watermark, no player lock-in.
Unlike · proprietary players or short soft-focus generations.
Drawn from your concept, not stock
Every animation is generated for your specific prompt. The pipeline writes the scene as code, renders it, and layers narration on top.
Unlike · template libraries with your logo pasted on top.
