Mike

Mike (MikeOSS) is an open-source legal AI platform for document review, drafting, and legal research.

It combines a Next.js frontend, an Express backend, Supabase Auth/Postgres, and Cloudflare R2-compatible object storage.

Features

• Chat with legal documents and open matters
• Review documents and apply suggested edits
• Run reusable assistant and tabular-review workflows
• Organize projects, folders, and a document library
• Verify citations and research US case law with CourtListener
• Work from Microsoft Word with the task-pane add-in
• Run supported language models locally through Ollama

Quick start

The included Docker Compose stack runs Mike, Supabase, RustFS object storage, and local email capture without requiring managed infrastructure.

1. Copy the local environment templates:

   cp .env.example .env
   cp backend/.env.example backend/.env
   

2. In backend/.env, set DOWNLOAD_SIGNING_SECRET and USER_API_KEYS_ENCRYPTION_SECRET to separate values generated with:

   openssl rand -hex 32
   

3. Add an Anthropic, Gemini, or OpenAI API key to backend/.env, unless you plan to use Ollama exclusively.

4. Start the stack:

   docker compose up --build
   

5. Open http://localhost:3000 and create an account.

To stop, run npm run stack:down rather than docker compose stop: stopped containers are never removed on their own and keep images and volumes in use. See "Stop and clean up" in docs/local-development.md.

The bundled credentials and infrastructure are intended for local development only. See Local development for service endpoints, authentication behavior, Ollama setup, and first-run guidance.

Telemetry

Mike sends scrubbed error reports (no document content, user identities, or request data) to the project's Sentry by default. Set SENTRY_DISABLED=true to opt out, or set SENTRY_DSN to use your own. See the observability guide for the exact policy, per-runtime variables, and the Sentry data audit.
