Turn any website into a stunning demo video
Wrap any site in a real device mockup, record it with your webcam and voiceover — or let the AI agent demo it for you — then add cinematic zoom. All without leaving your browser.
Everything in one extension
Record, narrate, and polish your demo — no extra tools, no exporting back and forth.
Real device mockups
Wrap any site in a pixel-perfect MacBook, iPhone, iPad, or Studio Display frame — with simulated iOS, macOS, and Windows browser chrome.
AI demo agent
Type a one-line brief and let the Gemini-powered agent click, scroll, and narrate the whole walkthrough for you — hands-free.
Webcam + voiceover
Drop in a draggable webcam bubble and record a microphone voiceover, all captured into one smooth HD video.
Cinematic zoom editor
Add non-destructive zoom anywhere the cursor moved, fine-tune it as keyframes, and export to MP4 or WebM.

Frequently asked questions
Everything you need to know about turning websites into demo videos with Screenlet.
What is Screenlet?
Screenlet is a Chrome extension that turns any website into a polished product demo video. Wrap the page in a real device mockup, record it with your webcam and voiceover — or let an AI agent demo it for you — then add cinematic zoom and export to MP4 or WebM, all without leaving your browser.
Do I need to sign up or install any software?
No signup and no desktop software. Just add the free Chrome extension and you can start recording right away. Mockups, recording, and the zoom editor all run inside your browser.
How does the AI demo agent work?
Type a one-line brief describing what you want to show. The Gemini-powered agent then browses the page on its own — clicking, scrolling, and speaking a voiceover — and records the entire walkthrough into a video for you, hands-free.
What's included for free, and what does the paid plan add?
Free gives you device mockups, recording, the zoom editor, webcam + voiceover at full 1080p, and 1 AI agent video (with a small screenlet.org watermark). The one-time $29 Lifetime plan removes the watermark, unlocks unlimited recordings and screenshots, includes 5 AI agent videos with affordable top-ups, and works on up to 3 devices — including all future updates.
Which devices and mockups are supported?
You can frame your site in a MacBook Pro 16, MacBook Air, Dell Latitude, Apple Studio Display, or iPhone 17 Pro Max — with simulated macOS, Windows, and iOS browser chrome — or use a wallpaper-backed floating screenshot.
What format are the videos exported in?
Videos export to MP4 or WebM at up to 1080p HD, ready to drop straight into landing pages, social posts, or app store listings.
Is my screen recording private?
Recording and editing happen locally in your browser using Chrome's tab capture — your video isn't uploaded to a server to be processed. The AI agent uses a single-use token to narrate, so your account credentials never leave the extension.
How do I get my license after paying?
After checkout, your license key is emailed to you. Paste it into the extension's settings to unlock everything instantly. Need more AI videos later? Top-up packs add credits to the same email you bought with.
Which browsers does Screenlet work in?
Screenlet runs in Google Chrome and other Chromium-based browsers that support Chrome extensions.
