Who Stet is for

Legal AI startups have strong proof and say "AI agents". Not one opens on a contract cleared against the playbook, with one clause left for counsel.

Stet is an AI agent that checks incoming contracts against a company's own playbook, inside Word and the email thread. It lets every standard clause stand and sends counsel only the one clause that needs a lawyer. Its buyer is the general counsel of a company of 200 to 2,000 people.

The numbers behind it

  • 3.1 hrsis the average time an in-house legal team spends reviewing a single contract. LegalOn survey, 2026
  • 8.6%of a company's annual value is lost to poor contract management, on average. WorldCC, 2025
  • 26%of sales staff say contract review takes more than 10 days. Only 3% of legal staff say so. Lexion survey, 2023

How the brand answers

Two films on a lightbox: cyan is the playbook, magenta is their paper. Where they agree, the contract prints dark. Only the difference shows colour, and that's the clause for counsel.

  • Stet reads a contract: clauses settle in register, one splits open for counsel, the fallback is accepted

    The one clause, split open

    The AI will wave through a clause I'd never accept.

    Stet reads Northwind's MSA against the playbook, clause by clause. 41 of 42 settle. The liability cap splits into two bands: their draft on magenta with its three changes marked, the playbook on cyan beneath, and a card with the fallback and two choices, send to counsel or accept the fallback.

  • The general counsel's phone: Stet's reply in the contract's email thread, and the Stet app on the home screen

    It answers in the thread

    Another platform, and our lawyers won't leave Word.

    There's no new platform to open. The general counsel gets Stet's reply in the email thread the contract arrived in: 41 of 42 clauses settled, one needs you, with the clause and the fallback right there. One tap sends the redline back.
