The open standard: Lemma

Lemma was created by the founders of LemmaBase.

Lemma is a standard language for business rules. It allows organizations to write down pricing, commercial terms, product features, tax codes and even law, in a clear and readable way, for every stakeholder to understand. Machines and AI agents can evaluate them exactly, with complete insight and explanatory traces for every outcome.

For Lemma to work as the global, interoperable standard for rules across nations and organisations, it has been released as free and open source software, supported by LemmaBase.

  • Readable by every stakeholder

    Skip translations to computer code. Avoid ambiguity.

  • Every answer comes with an explanation

    Lemma explains which rules applied and why.

  • Accountability without expiration

    Past and future rules are as important as today's.
