Write on one side. Paint, watch, read and explore on the other. Free and offline, on your own computer.

Whatever you make, there’s room for it beside the note.

For artists

Paint beside your thoughts.

Some ideas arrive as colour before they find their words. Paint the feeling first, and let the writing gather around it when the words come.

  • Round, flat, filbert and dry-bristle brushes, a palette knife and blending
  • A colour corner that thinks in harmonies, with an eyedropper for the drawing
  • Layers, pan and zoom — and a window onto the painting inside your note
Paint beside your thoughts.

For visual learners

Learn from the screen. Keep it on the page.

Some things have to be seen to be understood: the hands, the diagram, the demonstration. Watch closely, and keep the moment it clicked within reach.

  • A playlist stays one row, named by the episode you stopped at
  • The list steps back while you type, and returns when you look over
  • Chapters imported from the page, a description or a comment
Learn from the screen. Keep it on the page.

For writers

Build worlds, not just documents.

Every story is bigger than the page it lives on. Its people, places and loose threads get a room of their own, so the draft can be what it is meant to be: the telling.

  • Meta marks: select a name, press Ctrl+M, and it becomes a character, a place or a scene with its own details
  • Sidenotes beside any paragraph, that keep their place as the draft changes
  • A fractal map of your story — go down into any node, with the notes attached
Build worlds, not just documents.

For students

Everything for the exam, in one notebook.

Understanding is built page by page. Read closely, keep what matters, and every source you learned from stays one step away from the note it became.

  • Search, outline and pins that take you back to the page
  • Clip a figure from the PDF straight into the note
  • A library that keeps the sites and videos you spent time on — and web search beside the note
Everything for the exam, in one notebook.

Is Duenote free?
Yes, all of it, on every system.
Where do my notes live?
On your computer, as .2nt notebook files. A notebook reaches this site only when you publish it to the web reader.
Does it work offline?
Writing, painting, the Library and your PDFs all work offline. Web pages and videos need a connection.
Which systems does it run on?
Windows 10 or later (64-bit), macOS on Apple silicon, and Linux x86_64 as .deb, .rpm or AppImage.
Do I need a drawing tablet?
A mouse or a trackpad is enough for every brush.
Why does Windows warn me when I install it?
The Windows build is not code-signed yet, so SmartScreen shows “Windows protected your PC”. Choose More info → Run anyway, or install with the one-line command on the install page.
Is there a phone app?
Publish a notebook to the web reader and read it — sidenotes included — in any mobile browser.
