Mike

Mike, published as MikeOSS, is a legal AI platform covering document review, drafting and legal research. It brings the assistant to the matter rather than the other way around, letting a firm keep documents, matters and models inside infrastructure it operates.

The application combines a Next.js frontend, an Express backend, Supabase for authentication and Postgres, and Cloudflare R2-compatible object storage. Language models come from Anthropic, Gemini or OpenAI through an API key, or run locally through Ollama for teams that prefer nothing leaves the building.

The feature set follows the shape of legal work.

• Document chat: ask questions across open matters and the document library.
• Review workflows: reusable assistant and tabular-review workflows suggest edits you can apply.
• Citation checking: verify citations and research US case law through CourtListener.
• Word add-in: a beta task pane brings the assistant into Microsoft Word.
• Project structure: projects, folders and a shared library organize what a matter accumulates.

A bundled Docker Compose stack runs Mike, Supabase, RustFS object storage and local email capture without any managed service, so a first look costs one command. Those bundled credentials are for local development only, and a real deployment starts by generating your own signing and encryption secrets.
