A local-first notebook for engineers who want to capture ideas, meeting notes, and diagrams — without sending data to a server.
Built for engineers who document as they build. Local-first, customizable, and keyboard-driven.
Toggle a weekly view that groups entries by ISO week with signifier breakdowns, top tags, and entry previews. Collapsible week cards auto-expand the most recent. Filter by tag, text, or signifier — all filters work in review mode.
Start entries with structured sections. Decision Log, Debugging Session, Meeting Notes, Learning Log, and End of Day — each with pre-filled headings and auto-tags.
Mark entries that matter: decisions worth remembering, open questions, ideas to explore, or milestones to celebrate. Most entries need no signifier — that's by design.
Type [[ to link between entries. A "Referenced by" panel below each entry shows all backlinks — auto-maintained as you write.
Pin important entries to the top of your stream. Save tag + text filter combinations as named presets for one-click access in the sidebar.
Local storage by default. Optionally sync across devices with end-to-end encryption — entries are encrypted before leaving your browser. Use the default server or self-host your own.
