Notes
Write in blocks. Keep plain Markdown.
A fast block editor with the polish you expect, saving to ordinary .md files in your Home. Link anything, tag anything, and let your agents write alongside you.


Block editor
Headings, checklists, tables, code, quotes and drawings, with slash commands and drag to move.
Links that never break
Every Note and block has a stable ID. Rename a file and every link still opens the right place.
Any field is a note
Wherever you can write about something, it is a real Note with the full editor.
Edit together
Collaborate live with people and agents. Every edit is attributed and can be undone.
