Plan from the tab too
For a site the server cannot browse, the popup plans the script from your tab: the planner’s reasoning stays on the server and only the browser commands run here. Keep the tab visible; screenshots come from the active tab.

Record product demos in your own browser.
DemoBot Recorder is a Chrome extension that records a demo in the tab you pick: your login, your network, your tabs. Localhost, VPN-only tools and sites with bot protection become recordable, and DemoBot still adds the narration, captions, encoding and hosting afterwards.
Free · Chrome 116 or newer · Manifest V3
— when you need it
For the sites the cloud can’t reach.
The web app records in a browser on DemoBot’s servers. That works for most public sites and most logins, but not for a build on localhost, an internal tool behind your VPN, or a site whose bot protection blocks automation. The extension moves the capture into your Chrome, where you are already signed in, and uploads the recording to your workspace.

- Internal tools behind a VPN
- Sites that block automated browsers
- Pages inside your own logged-in session

upload, then narration and subtitles on the server
— how it works
Three steps, then the usual pipeline.
The extension captures; everything after the capture happens in your DemoBot account as it would for a cloud recording.
1 · Install and link
Add it from the Chrome Web Store, open the popup and link your DemoBot account, or paste an API key from Account, then API keys.
2 · Prepare the tab
Open the page, sign in, dismiss any cookie banner once. Pick a script you planned in the app, or plan a new one from this tab at short, medium or long.
3 · Record this tab
Chrome shows its debugging bar while the steps replay and the tab is captured. The video uploads to your workspace, where narration, subtitles and hosting are added.
Nothing runs in the background. The extension acts only after you start a session, only in the tab you chose, and reads no history and no cookies. Every permission, and why, is in the privacy policy.
— what else it does
Plan there, cancel freely.
Cancel refunds
Closing the tab, detaching the debugger or pressing Cancel aborts the run and refunds it. A capture left unfinished is refunded by the server after 30 minutes.
The same output
Narration, music, subtitles, intro and outro cards and the hosted player are all added server-side. An extension recording ends up as a normal DemoBot video in your library.
— known limits
What it doesn’t do yet.
Consent banners stay
The cloud recorder sweeps cookie banners off camera; the extension does not. Dismiss them once yourself, and your browser usually remembers.
No credential typing
Steps that type a login are filtered out of extension recordings on purpose. Record inside the session you are already signed in to.
Viewport is approximate
The window is nudged toward the script’s resolution preset and the capture is scaled to its bounds, but exact pixel sizes are not guaranteed the way the server’s fixed viewport is.
Re-record from the extension
Per-step re-recording and the pre-flight check need a server-side replay, which these sites do not allow. To redo an extension capture, record it again from the popup.
— faq
What people ask before installing.
Which browsers does it support?
Google Chrome 116 or newer. The extension is built on Manifest V3 and is installed from the Chrome Web Store.
What does it capture?
A video of the one tab you selected and a timing manifest of the scripted steps it replayed. During a planning session it also relays screenshots of that tab to the planner. Nothing from other tabs, no browsing history, no cookies.
Does it see my passwords?
No. Steps that would type a credential are left out of extension recordings by design; you record inside a session where you are already signed in. The only things stored on your device are your DemoBot app origin and your API key.
Where does the recording go?
Over HTTPS to your own DemoBot workspace, authenticated with your key. The server adds narration, music and subtitles, encodes the MP4 and hosts it on Cloudflare Stream, exactly as for a cloud recording.
Your browser records. DemoBot does the rest.
Plan the script in the app, record it in the tab that only you can reach, and get back a narrated, captioned MP4.
