Creating Notes
A new blank note
Click New Note in the sidebar footer, or ask the AI to create one. The note opens in edit mode with a title field at the top.
Give it a title and start typing. That's it.
Daily notes
Coeus has a built-in daily note. When you click New Note or ask for "today's note," Coeus creates (or opens) a note titled with today's date. If you write something small that doesn't need its own file, this is a good place to put it.
You can also append to today's note directly from the AI chat: just say "add this to my daily note."
Note types
When Coeus looks at your notes folder, it groups notes in the sidebar by type. The type is determined by the type field in the note's frontmatter: but you don't have to set it manually. Coeus guesses the type from the title if you use a template.
The types are:
| Type | What it's for |
|---|---|
| Tasks | Your to-do list |
| Journal | Daily notes and entries |
| Logs | Running logs of things (workouts, decisions, etc.) |
| Sources | Web pages, articles, books you've saved |
| People | Notes about people |
| Meetings | Meeting notes |
| Projects | Project notes |
| Books | Book notes |
| Concepts | Ideas, definitions, things you want to understand |
| Other | Everything else |
Note frontmatter
Every note can have a YAML block at the top between --- lines. This is called frontmatter. Coeus reads it for metadata.
---
title: My Note Title
type: project
tags: [work, q2]
---
You don't need frontmatter. Coeus works fine without it. But if you want tags or a specific type, that's where they go.
Editing a note
Click a note in the sidebar to open it. It opens in read mode. Click Edit (top right of the note panel) to switch to edit mode.
Edit mode has:
- A title field at the top
- A type field (optional)
- A tags field (optional, comma-separated)
- The editor below
Coeus saves automatically as you type. There's a 1-second debounce: it waits until you stop typing for a second before writing to disk.
Renaming and archiving
In read mode, the Rename button lets you change the title and filename without breaking any links to that note.
Archive moves the note to an _archive/ folder inside your notes directory. It disappears from the main sidebar but stays in search results. Nothing is deleted.
Notes are files
Your notes are plain .md files in the folder you chose during setup. You can open them in any text editor, move them around, back them up, or put them in Dropbox or iCloud. Coeus picks up any changes automatically.
