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.

- 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

The included Docker Compose stack runs Mike, Supabase, RustFS object storage, and local email capture without requiring managed infrastructure.
-
Copy the local environment templates:
cp .env.example .env cp backend/.env.example backend/.env
-
In
backend/.env, setDOWNLOAD_SIGNING_SECRETandUSER_API_KEYS_ENCRYPTION_SECRETto separate values generated with:openssl rand -hex 32
-
Add an Anthropic, Gemini, or OpenAI API key to
backend/.env, unless you plan to use Ollama exclusively. -
Start the stack:
docker compose up --build
-
Open http://localhost:3000 and create an account.
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.
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.

Gmail and Calendar are separate, optional connections in Settings → Connectors. Google SSO never connects them automatically. Choose any permitted Google account for each service, including a different account from your Mike login. Read access is the default; write permissions require a separate consent flow, and every send/edit/delete proposal requires explicit approval of its exact contents. See setup, technical approach, limits, and manual acceptance tests.
