Contract Radar

Reviews a contract against a company playbook and ties every risk to the exact clause it comes from.

Phase 2Node + TS · Size L

What a visitor does Reviews a contract and jumps to each risky clause

Problem

Small companies sign supply and wholesale agreements without legal review, and an AI summary without sources can’t be trusted.

Open the sample wholesale supply agreement or upload a contract. Read the risk radar across liability, termination, renewal, payment and IP. Click a finding to jump to the highlighted passage, then generate a redline.

Engineering highlights

The same pdf.js text layer runs on the server and in the browser, so citation offsets land on the exact characters.
Every finding must quote the contract verbatim, and the server checks each quote against the source text before showing it, so an invented clause never reaches the screen.
It flags missing clauses too, such as no liability cap. The playbook is editable data kept outside the prompt.
