- Worth noticing
- Notes stay local, with no account or cloud sync; the app itself is not an AI chat service.
Field notes
The homepage’s clickable prompts demonstrate sample task-list and progress notes without connecting an actual agent. In use, a connected agent writes or updates Markdown through the local CLI; users can edit, copy, color-code, resize, collapse, or link notes to files. The app stores notes locally, has no account or cloud sync, and the promised snapshot feature is explicitly still in preparation.
