Testing vs. verification.
Ship faster and focus on the details that matter in the age of AI-generated code.
Input coverage
With testingChecks only the inputs your tests and fuzzers run.
With Theorem VerificationProves the required behavior for every class of input your specification covers.
Checking a rewrite
With testingTests tied to the old implementation may need rewriting. Gaps in coverage can remain.
With Theorem VerificationKeep the requirements. Get a new proof that the rewritten code meets them.
Checking an optimization
With testingTests catch an unintended change only if they trigger it.
With Theorem VerificationProve the optimized code still meets the same requirements, including for edge cases.
Reviewing changes
With testingReview every code change and the tests intended to catch regressions.
With Theorem VerificationReview only the specification. A change that still satisfies it needs no further review.
What you get
- Clear requirementsA readable specification that states exactly what we’ll prove about your code.
- Proof you can checkA proof assistant validates each proof independently of the AI that produced it.
- Bugs uncovered during verificationWe share the bugs we find while proving your code meets its requirements.
- Evidence you can shareGive customers, auditors, and procurement teams checkable proof that your code meets its stated requirements.
