Tekne (formerly meditations) is a freestyle productivity app in the shape of an outline editor.
It's currently extremely alpha software! I'm using it every day now (as of 9/7/25) but it's missing lots of features, is sometimes broken in odd ways and does not yet have a stable database or document schema.
- tekne.app - website
- Demo - live demo; the built-in application help on the right has some help with syntax and keyboard shortcuts
Tekne is released under the AGPL. Tekne depends on a lot of projects, here are a couple:
- Codemirror and
@lezer/markdownform the core of the editor - Some Tailwind Plus templates and Tailwind Catalyst are used with a license for the app and website
- General stack: React with tanstack-router, express/TRPC for server, postgres (& pglite) for database, Jotai for state management
