The problem
Every major AI system carries a disclaimer: "I can make mistakes." But the answers sound authoritative. People act on them — in medical decisions, financial choices, legal situations.
The problem isn't that AI is always wrong. It's that you can't tell when it is — until it's too late.

Our standard
We tell you what we know, what we found, and what we couldn't verify. Transparency isn't a feature — it's the only way trust is built.
Trust is built slowly, through validation, track record, and never being wrong in a way that damages someone.
Confirmed by authoritative sources with citation
Directly conflicts with verified source material
No authoritative source found to confirm or deny
For everyone
