The problem

Freelancers, tenants and small businesses sign one-sided contracts because they can't afford a lawyer for every agreement, and the risky clauses are written to be hard to spot.

How it works

  • Each clause is matched against 32 market-standard benchmark clauses with pgvector similarity search and placed in a risk tier that doesn't rely on colour alone.
  • A redline view shows exactly what to strike and what to add, with the reasoning, and an attorney dossier packages the questions worth paying a lawyer for.
  • Names, addresses and account numbers are redacted in the browser before any text reaches the model.
  • Keyboard navigation, screen-reader landmarks and a read-aloud mode come built in; every view states that it informs rather than advises.

The result

Turns a dense agreement into a risk score, the clauses that matter most, and ready-to-send counter-proposals, without sending personal details to the model. Built for PromptWars Exclusive, open only to the top 400 from the first four challenges, where it earned 1,000 points in the AI-judged submission test.
