Integration details
Description
FALCON Verify checks whether an AI's answer is supported by the evidence it was given — the document, the figures, the record it was written from — and says so claim by claim. Paste an answer and its evidence, or ask ChatGPT to verify what it just wrote against the facts you supplied; FALCON extracts the material claims, settles what it can deterministically (numbers, names, dates against the evidence), sends the rest to a judge model, and returns a verdict for every claim: supported, qualified, unsupported, contradicted, or more evidence needed. Every result carries a hash-chained record of the decisions that produced it, which a stranger can check. It verifies against the evidence given, never against the model's own beliefs. Free for 25 verifications a month; Starter, Personal and Team plans after that. Nothing to install: sign in with Google, connect, and ask.
