TimeBinder
Prove your files existed before AI could rewrite them
TimeBinder launched on March 31, 2026.
What it does
AI is making document fraud and manipulation easier than ever. TimeBinder creates immutable proof that a file existed at a specific moment by anchoring its hash to the Bitcoin blockchain. Files (any file type/size) are hashed locally in your browser and never uploaded. Choose low-cost pooled TimeBinds or ASAP TimeBinds for totally independently verifiable timestamps on Bitcoin. Each TimeBind generates a Proof of Time Certificate with all verification data needed to prove authenticity.
Create independent, blockchain-verified proof of when files existed. TimeBinder timestamps documents, photos, and records to protect against AI tampering, forgery, and backdating.
TimeBinder creates verifiable proof that a file existed at a specific time by anchoring its SHA-256 hash to the Bitcoin blockchain. Files are hashed locally in your browser for privacy and can be independently verified at any time. Your file is hashed locally in your browser. TimeBinder never uploads or stores your file. TimeBinder submits your file’s cryptographic hash for anchoring on the Bitcoin blockchain. This creates an independent timestamp that can be verified later. You receive a Proof of Time Certificate showing the blockchain proof details needed for independent verification. Immutable proof for every industry that depends on trust, compliance, and verifiable integrity. A growing…from timebinder.io
