Demofy: AI Product Demo Video Maker

Let AI turn the page you're on into a finished, narrated product demo video, with nothing to record and no account needed.

Turn any public web page into a finished, narrated demo video — made by AI, not by you. Click the Demofy button on the page you want to show, say in one line what the demo should cover, and Demofy's AI explores the app in a real browser, films it with smooth zooms and adds a voiceover. • AI does the filming. You never record your screen: an AI explores the page the way a person would and Demofy films the flow it finds. • Narrated and zoomed. The camera follows each click and a voiceover explains what is happening. • One click from any public web page. The page's address is filled in for you — nothing to copy and paste. (A page behind a sign-in needs a saved connection in Demofy first.) • Free to start. There is no signup wall. • Yours to use. Download the finished video as an MP4 or share it. How it works. 1) Open the page you want a demo of and click the Demofy button in your toolbar. 2) Demofy opens in a new tab with that page's address already filled in. 3) Write one line about what the demo should show and press Create demo. 4) Watch the build log as Demofy explores, films and narrates, then download or share the video. What the extension itself does — and does not. It is only the shortcut in step 1. It reads the address of the tab you clicked on, at the moment you click, and opens a Demofy page with it. It does not run on the pages you visit, it does not read what is on them, it records nothing and it keeps nothing — there is no account, no login and no setting inside the extension. The permission, in plain terms. It asks for one: activeTab. Chrome grants that only when you click the button, only for the tab you clicked on, and takes it back as soon as you navigate away. It is the reason installing this shows you no permission warning at all. It does not ask to read your browsing history, and it does not ask for access to any site. After you click. The extension stops there. When you press Create demo on Demofy, the page address and your one-line request are handled by Demofy's service and sent to the AI model provider that plans the demo (DeepSeek), and the narration text goes to its voice provider (VoiceLabs).
