Local. Private. Designed for a real relationship with you over time — not just chat.
Mugi runs entirely on your Mac. It has a real personality system you control (PERSONA.md, USER.md, etc.). Background processes quietly pay attention to patterns and connections — then surface what they’ve noticed in clear, reviewable places.
You can accept, reject, or correct anything. Nothing happens behind your back.
The heart of Mugi: long-term relationship, not one-off chats. Background processes observe patterns across your conversations, notes, and activity. Insights surface as reviewable proposals in the You pane or as concrete work in Kanban.
Capture thoughts, voice memos, research snippets, and project notes directly in the app. Mugi helps organize them with projects/folders and a live knowledge graph.
Feed Mugi folders, documents, codebases, or research collections. It digests them into a durable, queryable expert knowledge base with synthesis, sources, entities, contradictions, and a graph.
Unlike generic RAG, Mugi compiles a real “expert” version of your material with explicit synthesis, provenance, and graph relationships. You can query it conversationally and the results feed back into the personal noticing layer.
See the Knowledge Library and Settings → Knowledge panes for corpus management, progress, and search.
Not a finished product. A serious attempt at something new, released so real people can tell us if the direction is worth pursuing.
The latest public preview is available directly. The app includes automatic updates via Sparkle once installed.
A proper user manual written for everyday people (with power-user sections) is already available, including dedicated coverage of the Vault and Knowledge Base.
