A local-first app reads Markdown notes, answers questions with citations, and maps recurring names into a clickable constellation.

Landing page captured for the 2026-09-15 issue.

Field notes

The app processes a user-selected Markdown folder locally, maintaining files, chunks, embeddings, and a recurring-name index. It chooses between vector retrieval for topic questions and full-mention reading for questions about a named person, then attaches citations to the answer. Its graph view links names that occur in shared notes, while new writing is saved back as Markdown and incorporated incrementally. The page illustrates the scale with 2,378 notes, 9,703 chunks, and 1,762 extracted names.
