Formal verification

Turing

Platform

How Turing works

Turing is a prover agent for teams shipping high-stakes software. It reads your contracts, drafts a formal specification with you, and searches for machine-checked proofs that your code satisfies each approved property across every input and every execution.

Differentiation

Why the approach is different

Turing uses a pure-functional stack with Haskell, Scala, and Coq to support cumulative proofs. Instead of treating verification as isolated theorem work, it composes reusable proof assets over time. Compared with Lean-centered one-shot workflows, this keeps more verification value alive through refactors, reducing repeated audit effort and accelerating release decisions.

Workflow

1. Import and model

Bring in your contracts and implementation artifacts. Turing constructs a precise model scope.

2. Review the specification

Approve properties in plain language, pseudocode, and formal form before proof spend begins.

3. Prove continuously

Proof search runs under your budget cap and emits replayable artifacts for each solved property.

4. Re-check on every push

CI catches behavioral drift early so evidence keeps pace with your shipping cadence.

Outcomes

Three outcomes per property

Proven

A replayable, machine-checked theorem your team and external reviewers can independently verify.

Refuted

A concrete executable counterexample that reproduces the failing path so fixes are immediate.

Not yet proven

A transparent report that a property was not solved under the current spend cap and constraints.
