The Garden plan note in Marrow: a title, tags, properties, a paragraph with a highlighted word and links, a task list, and a panel of backlinks and a small graph.

Take a look around

Real screens from Marrow 1.8 on a computer. Pick one to see what it does.

Home, your own board

The first thing you see. Arrange cards however you like: what's due this week, today's note, a quick note box, recent notes, a calendar, sticky notes and more.

The same notes on every screen

Windows, macOS and Linux on computers. Android, iPhone and iPad on phones and tablets. Each one is a real app built for that device, not a web page in a box, and they all read the same folder.

Keep them in step with your own Google Drive, OneDrive, Dropbox, iCloud, a WebDAV server, or any folder that already syncs. Turn on end-to-end encryption if you like; your notes never pass through our servers.

Get the most out of Marrow

Nine habits that make Marrow pay off. Start with the first three; add the others when you need them.

  1. Keep everything in one folder

    Marrow works on a folder of notes, called a vault. Make one for everything: work, home, reading, ideas. Subfolders are fine, but don't spend long on them, because links and search do most of the sorting for you.

    Already use Obsidian? Open that folder; it just works. Coming from Notion or Evernote? Import notes in Settings brings your notes over, with step-by-step help.

    The sidebar: folders called Daily, Projects, Reading and Templates, with notes inside.
  2. Start each day in today's note

    Today's note is a page for the date with two parts: Log for what happens and Tasks for what to do. Write a line whenever something comes up. Over weeks it becomes a diary you can search.

    Try it: Ctrl D opens today's note. Ctrl Alt N drops a quick note into it from any app.

    Today's note for 4 November: a log with three timed lines and a short task list.
  3. Link as you write

    Type [[ and a few letters to link another note. Every link works both ways: the note you link to lists this one under Linked mentions. Link to a note that doesn't exist yet and it's waiting for you when you click.

    Unlinked mentions shows notes that name this one without linking it. One click links them.

    Try it: Ctrl + click follows a link while you edit.

    Typing [[Gar in a note shows a suggestion: Garden plan, in Projects.
  4. Tag lightly, and keep facts in properties

    Use a #tag for a theme you'll want to gather later, like #reading or #work. A few good tags beat dozens of rarely used ones.

    Put facts you'll sort or filter by, such as a status or a date, in the note's properties at the top. Databases can then show them as a table, a board or a calendar.

    The top of a note: tags garden and home, and properties for status, season and tags.
  5. Turn lines into tasks with dates

    Start a line with - [ ] to make it a task. Add a date with 📅 2026-11-05, and a reminder with ⏰ 2026-11-05 17:30 or the bell button. Your computer or phone tells you when it's time.

    Every task from every note gathers in Tasks, on the Calendar and on Home, so you can write tasks wherever they come up and still see them all in one place.

    The Tasks list: overdue, today and upcoming tasks, each with its note and date.
  6. Make Home your dashboard

    Tap Edit on a phone, or use Add and Customize on a computer. Show the tasks you care about: the next 7 days, one tag, one folder, or any dates you pick. Pin a sticky note, one section of a note, a countdown or a clock.

    Start from a template such as Week planner or Study. Save yours as a .marrowhome file to share; words on sticky notes stay out unless you choose to keep them.

    The Customize panel for a sticky note: style, colour, colour strength, text colour, font, size, alignment and corners.
  7. Draw when words aren't enough

    Type /drawing on an empty line, or use the Drawing button, and sketch right in the note: boxes, arrows, a quick map, a screen idea. On phones and tablets, draw with a finger or a pen; the hand tool moves and resizes what you've drawn.

    For the bigger picture, open a Canvas and lay out whole notes side by side.

    A drawing inside a note: boxes for screens, a diamond, a cloud and a cylinder joined by arrows.
  8. Find anything in two keys

    Ctrl K finds a note by name and runs any command. To look inside every note, use Ctrl Shift F. Search understands "exact phrase", -word to leave something out, tag:#garden and path:Projects.

    When you can't remember a word at all, open the Graph and follow the links, or ask your notes a question with Ask (bring your own AI key, or run one on your computer).

    The command palette with the letters re typed, listing notes and commands that match.
  9. Keep it safe and in sync

    Connect your own Google Drive, OneDrive, Dropbox, iCloud or WebDAV under Sync in Settings, and the same notes appear on every device. Lock private notes or whole folders with a password.

    Marrow keeps every version of every note: Version history compares and restores them, and the time machine shows your whole vault as it was on any past date, deleted notes included.
