Conversion Lab

Local document conversion, bound to a verifiable receipt.

The Lab runs heavier conversion engines than the main AINumbers.co site carries. Every conversion still happens entirely in your browser: nothing is uploaded, and each tool computes an input and output digest with WebCrypto so you can attach a provenance receipt to what you produced.

What a receipt proves, and what it does not.

A receipt binds the digest of what you fed in, the digest of what came out, and the identity of the engine that ran. It is evidence of this run, independently re-verifiable by anyone. It is not a claim that the same engine version will always produce byte-identical output; conversion engines are not guaranteed to be bit-stable across releases.
