Local-first personal knowledge management with first-class structured and geospatial (GIS) data. Your notes, contacts, appointments, tasks, locations, and tracks live as plain, human-readable files (Markdown / JSON) and are exposed over standard sync protocols.

What it does

PKM core — Markdown notes, linkable to everything else.
Structured records — contacts, events, tasks with defined base schemas.
Standard sync — CardDAV (contacts) and CalDAV (events + tasks), so existing clients work directly against your data.
GIS — store coordinates and GPX tracks; view collections of geo data on a map.
Extensible — add custom fields and types on top of the built-in primitives.

Principles

Local-first — works offline, data stays with you, sync is additive.
Open & readable — everything is plain Markdown / JSON on disk; no lock-in.
Extensible core — built-ins can be extended without breaking the standard CardDAV/CalDAV mappings.

Status

Early / greenfield. Tech stack to be decided.
