Demoscope Recorder

Record browser interactions with screenshots and export as demoscope capture bundles

Demoscope turns anything you do in your browser into a shareable demo. Click record, walk through your product, and Demoscope captures every click, keystroke, scroll, and page change — each with a screenshot — then hands you an in-browser editor to turn it into a polished video or a written guide. No Playwright, no CLI, no server. Because it records what you actually see, it works on pages behind a login. ▸ TWO OUTPUTS FROM ONE RECORDING • Video — an auto-edited MP4 or GIF with smooth cursor motion, animated clicks, auto-zoom on the action, subtitles, and annotations. • Step-by-step document — an editable, numbered guide with a screenshot per step. Copy as Markdown, download Markdown + images, or print to PDF. ▸ HIGHLIGHTS • One-click recording of clicks, typing, scrolling, key presses, and navigation. • Works behind auth — it records your real session, so gated and internal pages just work. • In-browser timeline editor — trim, cut, split, auto-zoom, subtitles, annotations, and crop. • Recording library — recordings are stored locally; reopen, rename, or delete anytime. • Keyboard shortcuts and a guided tour to get moving fast. ▸ PRIVACY Everything happens locally in your browser. Demoscope has no server and no account — your recordings never leave your machine. It does not collect, transmit, or sell any data. ▸ HOW IT WORKS 1. Open the page you want to demo (including anything behind a login). 2. Click the Demoscope toolbar icon and Start Recording. 3. Interact with the page — every step is captured with a screenshot. 4. Click the icon again and Stop & Preview to open the editor. 5. Edit and export a video, or generate a step document. MP4 export uses the browser's WebCodecs encoder. GIF and WebM export work everywhere.
