Certora AI Composer
Direct answerCertora AI Composer pairs LLM code generation with the Certora Prover so generated Solidity is checked against invariants before it is accepted. It is a secure-generation tool rather than a scanner, and the clearest example of LLM plus formal verification.

What Certora AI Composer does
The pattern, model proposes and prover disposes, is the same one better.codes and Clean use in the ZK world.
Where it is strong
- Proof-checked output.
- Open source.
Limits and caveats
- Alpha.
- Generation, not auditing.
- Invariants must be written.
When to choose it
Use when generating contract code that has formal specs.
