Show HN: Duffel – search centric LLM friendly workspace (github.com)

Duffel is a local-network markdown workspace for human + LLM collaboration.

It provides Web UI for browsing and editing notes & Lightweight CLI for search-first retrieval (using qmd).

I've found it to be very helpful for projects that require agents to have a lot of data in certain situations and they are actually quite fastidious about recording learnings and keeping everything tidy.
