Hi everyone — I’m the solo founder behind this extension. I built it because tweets disappear constantly, and screenshots just aren’t reliable anymore. Journalists, analysts, and everyday users need a way to capture tweets with proof, not just pixels. I’d love your feedback — bugs, ideas, feature requests, anything. Thank you for checking it out and supporting the launch.
Content Proof - Backup & VerifySave disappearing tweets with cryptographic proof
Content Proof is a Chrome extension that automatically
backs up every tweet you post with cryptographic
verification. The moment you tweet, it creates a
SHA-256 hash—an immutable mathematical proof of
exactly what you posted and when. Everything is stored
locally on your device (privacy-first, no servers).
If a tweet gets deleted, edited, or disputed, you have
undeniable proof it existed. Search your entire tweet
history, export verified archives, and generate
shareable proof pages.
