Formel combines generative AI with formal verification using the Lean 4 theorem prover to ensure that model outputs are logically consistent and adhere to encoded regulatory, legal, or business constraints. The platform automatically generates provable proofs and traceability logs for each response, enabling auditability and consistency checks across large document sets while reducing computational costs. It targets regulated industries that require trustworthy, compliant AI for document generation and decision support.

Problem
Enterprises that rely on generative AI face frequent hallucinations, difficulty enforcing regulatory or business constraints, and limited transparency, which can lead to non‑compliant outputs and costly errors. Traditional large language models lack formal guarantees of logical consistency, making it hard to audit decisions across large document sets or ensure adherence to legal requirements.
Solution
Formel integrates generative AI with formal methods, using the Lean 4 theorem prover to verify model outputs against mathematically defined constraints. By embedding formal verification into the inference pipeline, the system eliminates reasoning hallucinations even over long chains of thought and makes it impossible for the model to violate specified regulatory, legal, or business rules. All generated content is accompanied by provable traceability, allowing users to audit decisions and prove consistency across thousands of documents. This approach delivers reliable, transparent AI while reducing computational overhead compared with conventional large language models.
Target Audience
Primary customers are regulated industries such as finance, legal, insurance, and compliance‑heavy enterprises that need trustworthy AI for document generation, policy enforcement, and decision support.
