Content Proof - Backup & Verify – Save disappearing tweets with cryptographic proof

Summary: Content Proof is a Chrome extension that backs up tweets by creating a SHA-256 hash as cryptographic proof of their content and timestamp. It stores data locally, enabling users to verify deleted or edited tweets with immutable evidence. Users can search, export archives, and generate shareable proof pages.

What it does

It automatically hashes each tweet upon posting and saves the proof locally on the device. This process ensures an unalterable record of tweets for verification.

Who it's for

Journalists, analysts, and users needing reliable, verifiable backups of their tweets.

Why it matters

It solves the problem of disappearing or altered tweets by providing undeniable cryptographic evidence of their original content and timing.
