Verification Layer
TPMN Checker
Verification for AI reasoning. Analyze AI outputs and detect reasoning violations before they reach production.
What TPMN Checker detects
Instead of blindly accepting AI output, TPMN Checker audits the reasoning itself. It identifies problems that are difficult to catch because the reasoning sounds plausible.
TPMN Checker transforms AI usage from guess-and-trust into verify-then-use.
