# Your demo re-shoots itself when your product changes. Self-maintaining demo videos Paste a URL and one line of intent — Demofy films your app into a narrated demo, records behind your login, and shoots it again when your UI moves. - [Claude Code](https://demofy.io/agent-setup/claude-code) - [Codex](https://demofy.io/agent-setup/codex) - [Cursor](https://demofy.io/agent-setup/cursor) - [OpenCode](https://demofy.io/agent-setup/opencode) The output ## Every beat is a decision A demo is not a screen recording with a mouse wandering across it. It is a shot list: where the camera sits, when it moves, and what made it move. A real Demofy demo — Wikipedia, 17.7s, nothing cut.

Demofy's are plans it can shoot again — on your word, or on its own when a capture finds the app has moved. 1. 01 ### A plan is recorded 2. 02 ### Your app moves 3. 03 ### The capture stops 4. 04 ### It re-shoots itself Automatic, and once per demo — never a retry loop. The old version is never overwritten, so a link you already sent keeps playing. - 01 ### Re-shoot it when the UI moves One button sends Demofy back through your app from scratch — same URL, same intent, today's interface — and films it again. - 02 ### A dead beat heals itself When a capture cannot find an element it recorded, Demofy says which one in plain English and re-shoots the demo automatically, once. - 03 ### Every re-shoot is a version The old video is never overwritten. The versions sit in one chain on the job page, and a link you already sent keeps playing. - 04 ### It records behind your login Sign in once in a browser Demofy drives, save the session, and it films the product a logged-out visitor never gets to see. - 05 ### No signup, no card, nothing to install Paste a URL on this page and the first demo starts. An account is for keeping a library — it has never been the price of making a video. Where that pays off, job by job: [product demo video use cases](https://demofy.io/use-cases) How it works ## Four phases, and you watch all of them Demofy streams every phase to your job page as it happens, so a long render reads as work rather than as a hang. 1. 01 ### Discovery A model reads your app one screen at a time and writes the plan — the only half that calls one. 2. 02 ### The recording is a file you can re-run Every click, every line of narration and every camera move is written down. That written-down demo is the thing Demofy keeps — so it can make the video again without planning a single step again. The file is demoscript.json: discovery writes it, and the second half only replays it. 3. 03 ### Your finished video never depends on an AI service Only the planning half reads your app with a model. Filming replays the plan in a container, so the same plan gives the same video — today, and the day an AI provider has an outage. No model and no API key in the render path, enforced by a lint rule and a CI check. Two halves that never call each other. The plan is the only thing that crosses — which is why a re-render costs no model spend and never re-plans. 1. queued — job accepted, quality tier locked for the run 2. discovering — a numbered digest of every interactive element on the page 3. discovering — shot list written: which controls to touch, in what order, what to say 4. capturing — a real browser replays that plan, with no model in the loop 5. capturing — typing at 45ms per keystroke, filmed for a 60fps cut 6. compositing — camera beats resolved from the pointer’s measured arrivals 7. compositing — motion blur on the moves only, never on a held frame 8. compositing — narration and captions muxed onto the timeline 9. uploading — final.mp4 to object storage 10. done — ready to watch The phases above are the real state machine, in order — queued and done are its bookends, and the work between them is what your job page prints live, with elapsed time, as your demo is built. The same job by hand, step by step: [how to make a product demo video](https://demofy.io/how-to-make-a-product-demo-video) Why it looks right ## A camera language, not a zoom effect The camera goes where the pointer goes, and it only moves because the pointer moved. Watch the rig below: the frame chases the cursor, and it re-anchors only once the cursor has left the dead zone. - 1.00×1.35× camera framefollow dead zone - 01 ### Every move is motivated No drifting, no breathing, no fidgeting. A hold with nothing to look at rests genuinely still. - 02 ### 1.8× is a hard ceiling One zoom per beat, every beat clamped, and a return to a full uncropped 1× when the subject is done. - 03 ### Smooth, cinema-style camera moves When the camera moves, the frames blur the way a film camera blurs them. When it holds, they stay perfectly sharp — so nothing smears and captions stay readable. A 180° shutter, velocity-gated: below a threshold of travel a frame renders at a single instant. - 04 ### Re-renders replay the plan The plan is a stored artifact. Re-rendering a finished demo replays its steps with no model call; only a re-shoot explores the app anew.
