thesaraharminta · x · 2026-11-04
Fennick is a free, local, private PKM notebook built for "you and your agent together." In a demo, Claude planned Thanksgiving dinner: it created the page and cover, added each dish as a recipe with properties and photos, and saved a table view of the menu.
- Claude's output is ordinary Fennick content — editable, taggable, queryable like your own notes
- Every change is marked as Claude's in the Op Log and individually undoable
- Notebooks stay as files on your own computer
