Every shot exists in both appearances. Use the appearance control in the menu bar above to switch — HelloNotes itself does the same, following your Mac or pinned in Settings.


Your notes, your files
The sidebar is a view of a real folder on your Mac. Collections, folders, tags and bookmarks — over ordinary Markdown files you can open in any other app.


Maths and diagrams, rendered inline
LaTeX maths and Mermaid diagrams are drawn natively in the editor as you type — no browser engine, no export step, no round trip.


Callouts, properties and rich Markdown
Collapsible callouts, hidden comments, and front matter presented as a typed, editable Properties panel rather than raw YAML.


See how your thinking connects
The graph view maps links between notes, with arrows for direction and focus tracing to follow a thread through the collection.


Ask your library
Ask a question in plain language and get an answer grounded in your own notes, with citations back to the sources — running on-device.
