Mike

Mike is an open-source legal AI platform for law firms. It is built for teams that want to run, inspect, and control their own legal AI system, with documents kept inside their own infrastructure.

The platform includes a chat interface that reads documents, gives grounded citations, researches case law, runs multi-step workflows, and drafts and edits contracts end to end. It supports matter-scoped workspaces, called projects, where users can upload credit agreements, SPAs, leases, and diligence packs, and the assistant keeps full context across conversations and documents. Mike also offers spreadsheet-style tabular review for extracting information across hundreds of documents in parallel, with each cell cited back to a page and a quote. Saved workflows can be reused for tasks such as CP checklists, credit agreement summaries, and change-of-control reviews, and the site also lists workflows for areas including e-discovery, supply agreements, SPAs, NDAs, commercial leases, limited partnership agreements, shareholder agreements, and employment agreements.

Mike is delivered as open-source software and can be used through a cloud-hosted version or by deploying the source code. The product is self-hostable by design, and the page says documents never leave the user’s perimeter. It is described as working with Claude, Gemini, or OpenAI using the user’s own keys, and it can be extended with practice-specific workflows, document management system integrations, and a custom citation engine. The site says the codebase is open, with auditability for prompts, citations, and data flow.

The pricing model is described as having zero license cost and no per-seat pricing; users pay only the model API costs. The page also states that the software is open source and that firms can fork it and extend it.
