VouchShot is a Chrome extension that captures screenshots with built-in cryptographic proof, making them publicly verifiable to combat fake screenshots and build trust with audiences.
What is VouchShot?
VouchShot is a Chrome browser extension that captures screenshots and cryptographically signs them to produce tamper-evident images and a public verification page. It takes a screenshot of any web page as input and outputs a verified image file alongside a unique verification URL (e.g., https://vouchshot.com/verify/VS-SVFF-JBH5-NN77). The tool is developed by Mnemo and is free to start with 10 verified screenshots per month.
Key Features
- Public verification page — Every screenshot gets a unique URL where anyone can audit capture details, including domain, timestamp, and cryptographic signature. See a live example.
- Proof analytics — Track views, unique visitors, and traffic sources for each verification page.
- Per-platform QR codes — Generate unique QR codes for different platforms (Twitter, LinkedIn, etc.) to track which channel drives verification traffic.
- Mutation report — Shows exactly what changed on the page during capture, so viewers can see no meaningful manipulation occurred.
- Beautify studio — Enhance verified screenshots with backgrounds and annotations after capture, without breaking the proof.
- Creator profile — All verified screenshots live at vouchshot.com/@you, building a public portfolio of auditable claims.
- Clean reload & DOM certification — The page is reloaded before capture, and the DOM structure is certified at the millisecond of capture.
- Hash & sign — Image, URL, and timestamp are cryptographically signed and stored on a public record.
