The Cliff Walk at Pourville by Claude Monet

Features

Everything the incumbents ship, in an open codebase your firm owns.

Assistant

A chat interface that reads your documents, cites verbatim, runs multi-step workflows, and drafts and edits contracts end-to-end. Plug in your own Claude or Gemini keys, and keep full control of the models you use.

Projects

Matter-scoped workspaces. Upload credit agreements, SPAs, leases, and diligence packs into a project; the assistant keeps full context across every conversation and every document.

Tabular review

Spreadsheet-style extraction across hundreds of documents in parallel. Every cell is verifiably cited back to a page and a quote, with no hallucinated answers or dead links.

Workflows

Save proven prompts as reusable workflows, including CP checklists, credit agreement summaries, and change-of-control reviews. Create firm-wide templates your juniors can run in one click.

Why open source

Your firm’s AI, on your own terms.

Zero license cost.No vendor lock-in. No per-seat pricing that rises every year. You pay only the model API costs. Use Claude or Gemini with your own keys.Self-hostable by design.Deploy inside your own infrastructure. Documents never leave your perimeter. Compliance, residency, and privilege stay under your control.Fork it. Extend it.Add practice-specific workflows, integrate your DMS, wire in your own citation engine. The codebase is yours to shape.Audit every line.No black boxes around how prompts are built, how citations are parsed, or how data flows. Open code, open prompt-engineering.

Start in the cloud. Or clone the repo.

A working substitute for Harvey and Legora, available as a hosted product or to self-deploy from source.
