Lehvel / Labs

We test AI on real work and write down what held up.

Each entry records the question, what we built, what the evidence shows and where it falls short. Failed tests are published too.

Systems and experiments

Software we built to run Lehvel or deliver client work.

  • Sales Desk

    Our client sites run on checked facts, so our sales record does too. One system carries a customer from first conversation into delivery.

  • How Lehvel's AI systems hand work to each other

    We got tired of carrying prompts and status between AI systems by hand. So we built a shared system that does it, with GitHub as the record.

    Running experiment

Bounded tests with one question and a measured result.

  • Audit Lab

    Audit Lab is a website check that ties every finding to something it measured, and says could not check when it could not. In October 2026 one report broke that rule.

    Running experiment

  • What if the expensive AI is doing the wrong job?

    We are testing whether a small AI model can handle the many small judgments around big-model work, without being allowed to act.

    Running experiment

  • Running operations by voice

    Owners do not update forms. We are testing whether an owner can say what changed and have it become a change to the business record.
