Mike (local-only fork)

A fully local fork of willchen96/mike — all credit to Will for the original project, which is genuinely awesome.

This fork swaps out the cloud dependencies (Supabase Postgres, Supabase Auth, Cloudflare R2) for local equivalents — a JSON file for state and the local filesystem for document storage. Nothing leaves your machine except calls to the LLM provider you configure.

Why? I'm a personal injury lawyer. I sometimes work with contracts, settlement docs, and client materials I'd rather not push to a third-party cloud bucket while I'm just experimenting with a tool. This version lets you kick the tires entirely on your own laptop. If you want the full multi-user / production setup, use Will's upstream repo — it's the right tool for that job.
