The editor
One text, three views
A note is Markdown. How you look at it is up to you, and you can switch at any time without converting anything.
- Rich — headings, bold, lists, checkboxes, tables, links and code blocks, with a formatting bar
- Plain — just the text, for when formatting gets in the way
- Code — line numbers, syntax highlighting, a minimap, word wrap and go-to-line
- Switching view never rewrites your text
Organise
Projects, tags and deadlines
Structure appears when you need it and stays out of the way when you do not.
- Projects with their own colour, created and renamed from the Explorer or the note itself
- Tags for topics that cut across projects — filter from the sidebar or search
#tag - Due dates with badges that turn amber within three days and red once late
- Upcoming, Overdue, Today and Favourites views built in
Search
Find anything, fast
⌘K opens one box that searches note titles, their contents, tags and projects, and shows the matching line as a snippet.
- Regular-expression find and replace, in one note or across all of them
- Quick open by file name when you are working in a folder
- Go to line, keyboard shortcuts and every menu command from the same box
Claude & MCP
Claude works in your notes
GlissNotes is an MCP server as well as an app. One click in Settings adds it to Claude Desktop or Claude Code.
- Tools: list and search notes, read, create, append, update, and save prompts
- Prompts you save appear in Claude’s own prompt list
- Runs locally over stdio — nothing is uploaded anywhere
- Notes Claude changes appear in the app as soon as it regains focus
Files
A real code editor when you need one
The engine behind the code view is built for large files: a piece table keeps edits fast whether the file is ten lines or a hundred thousand.
- Line operations: duplicate, move, join, sort, dedupe, trim, change case
- Tabs, a folder tree, quick open, recent files and reopen-closed
- Encoding and line endings shown in the status bar, with conversion
