01

Markdown, natively

Headings, lists, quotes, tables and code fences. Your notes are plain text, readable anywhere, forever.

02

Notebooks & sheets

One notebook per project, as many sheets as it needs.

03

Find anything

Search every sheet in every notebook. Titles rank first, with a snippet in context.

04

Share a sheet, not your notebook

Every sheet has its own public link. Readers see just that sheet, never the rest of your notebook, and they don’t need an account.

05

Code that looks the part

Fenced code gets syntax highlighting and line numbers in the reading view.

06

Saved as you type

Edit in two places at once and OpusNote warns you instead of overwriting your work.

How it works

Three steps. No manual.

  1. Write

    Open a sheet and start typing. Plain markdown, a rendered view one click away, and your words saved as you go.

  2. Organize

    Group sheets into notebooks. Every sheet has its own address, so you can bookmark it or link straight to it.

  3. Share

    Send one sheet to anyone with its public link. They get a clean reading view, and no sign-up wall.

The app

Calm by design.

Notebooks on the left, sheets beside them, your writing in the middle. Nothing to configure and nothing in the way.

The OpusNote app: a list of notebooks, the sheets in the selected notebook, and a rendered recipe with a highlighted code block.
