Ledger lookup

Is this already on the record?

Paste any AI output and search 23,000+ recorded works — the whole ledger, not a recent slice. If something like it is there, you'll see who recorded it first.

Compares your text by meaning against the whole ledger, so a rewrite or a changed line still matches. Your text is sent to the server to be compared — it is never published, never certified, and not kept.

DEUSPROOF records existence and time — it does not, by itself, adjudicate authorship. You draw the conclusions.
