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.
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.
