Product demo videos in minutes, not weeks
Describe the demo. Your AI agent builds it scene by scene — screen capture, effects, voiceover, captions — and renders it on your machine. Change anything later by asking.

Real demos, shipped
Every one of these shipped for a real product, built end to end in CoAnimator.
how it's built
How to make one in CoAnimator
- 01
Describe it
A brief in plain language: what the video shows, the moments that matter, the tone. No timeline surgery.
- 02
The agent builds the scenes
Claude Code, Codex, Gemini or ours — the agent authors each scene as editable code on the templates and skills the studio ships.
- 03
Narration lands timed
The built-in voiceover plugin renders the narration part by part and places every line on the timeline where it belongs.
- 04
Review in the editor
Timeline, media panel, live stage. Steer with feedback — "slow the intro", "swap that screenshot" — and watch it hot-reload.
- 05
Render locally
MP4 exports run on your machine, in-app or headless via the coa CLI. Unlimited, watermark-free, nothing uploads anywhere.
everything included
No credits, no per-render fees.
Templates, effects, plugins, voiceover wiring and unlimited local rendering ship in the studio. Your footage never uploads to a render farm — exports run on your machine, as many as you want.
FAQ
What’s the best way to make a product demo video without a video team?
The fastest path is an agentic studio: in CoAnimator, an AI agent builds the demo — screen footage, callouts, motion graphics, pacing — from your plain-language brief, and you direct revisions instead of learning an editor. It renders locally to MP4 on Windows or macOS, with no credits or watermark.
Can I update a demo video when my product UI changes?
Yes — that’s the point of file-based projects. Swap the changed screen recording or ask the agent to re-do the affected section, and re-render; the rest of the demo is untouched. With the coa CLI you can even re-render updated demos from a script.
Can CoAnimator add callouts and motion graphics on top of my real screen recording?
Yes. The real-footage effects template layers animated callouts, spotlights, zooms, and color pops over your actual recording, and the motion-graphics template can rebuild key moments as pure animated UI. Both ship in-app with sample projects to open and study.
CoAnimator vs screen recorders like Loom or Screen Studio — which for demo videos?
Screen recorders are the right tool for quick, personal walkthroughs — recording yourself once and sharing fast. CoAnimator is for produced demos: an agent designs motion, narration, and pacing around your footage as an editable project you can revise release after release. Many teams use both; the produced launch-page demo is where CoAnimator earns its licence.
