Every TrustCheck assessment can generate a Proof Receipt — a timestamped record of the credibility check. Each receipt includes a Proof ID, claim hash, source domain, timestamp, judgement, and verification status.

Proof Receipts let you keep a record of what was checked, when, and what the assessment concluded — without requiring an account or database.

Private API prototype now available for early testers.

Build credibility checks into AI apps, research tools, browsers, and digital workflows.

The TrustCheck API analyzes claims and returns structured credibility signals including claim type, risk level, external verification status, recommended checks, and Proof Receipt metadata.

TrustCheck does not claim to prove truth. It helps platforms identify when claims need further verification before users trust, share, or act on them.

TrustCheck is building credibility and provenance infrastructure for the AI internet. The roadmap includes proof receipts, source reputation, human review layers, APIs for publishers, and eventually tamper-evident proof anchoring — so that credibility assessments become a durable part of how information is evaluated and shared online.

Beta note: TrustCheck is currently in private beta. Results may be imperfect.
Disclaimer: TrustCheck provides credibility analysis and proof records. It does not independently prove that every claim is true.
