Clause Compass
A structural-search engine for legal and financial documents that lets lawyers, compliance officers, and finance teams run pattern queries across large contract corpuses the way engineers run ast-grep across code, surfacing clauses that match a structural rule rather than a keyword.

- Structural search across uploaded contract corpuses (e.g., find "every change-of-control clause with threshold > 30% and a defined-term carve-out")
- Clause-level diff viewer for redlining versions of the same contract family across deals
- Taxonomy of clause types with risk indicators (auto-renewal, unilateral termination, IP assignment, etc.) so non-lawyers can self-serve common reviews
- Audit trail showing which clauses were reviewed, by whom, and the version timestamp, exportable as a diligence memo
The ast-grep Rust rewrite proves fast structural search on tree-shaped documents is now practical on real-world workloads; contracts, NDAs, MSAs, and regulatory filings are exactly the kind of deeply nested documents structural grep was made for, but the only tools that offer this (Kira, Luminance, Evisort) cost $50k+/year and remain out of reach for mid-market teams.
