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.
