michi-chatA chat assistant platform for small businesses

Quickstart

For business owners

One instance, many businesses

Each tenant gets its own persona, branding, tools, knowledge base, embed key and daily spend cap. Adding tenant

Any model, by config

The app only knows three aliases (michi, judge, embed). LiteLLM decides what serves them, so moving from local Ollama to a hosted provider is a yaml edit.

Built for strangers

The public endpoint assumes untrusted traffic. Origin allowlists, server-minted sessions, rate limits and a hard daily cap protect the bill against anyone with curl.

Grounded answers

A pgvector knowledge base with heading-aware chunking and a measured recall@k eval. The bot says "I don't know" instead of inventing facts or prices.

Good to know

There is indeed a cat in Geneva named Michi. Every project in this workshop is named after Michi, and this is Michi's contribution: sleeping through the code review, then taking the credit.
