ProofChain AI

Verify mathematical proofs and suggest completion strategies

Research AIFreemium

ProofChain AI checks formal and semi-formal mathematical proofs for logical gaps, unstated assumptions, and incorrect inferences. It interfaces with proof assistants like Lean and Coq while also accepting natural-language proofs and identifying where formalization would catch potential errors. Mathematics researchers use it as a verification companion that catches subtle reasoning errors before peer review.
