BUILT ON HONESTY Claude clearly labels what it can and cannot verify. Claims requiring real-time data, breaking news, or post-training information are marked as "Unverifiable" rather than guessed at. This tool provides AI-assisted reasoning — not absolute truth. Always cross-reference with authoritative sources for critical decisions.
