Lay out notes, diagrams, and code on one open canvas. There is no account to create, and your work stays in your browser.

The Barrio Notes canvas with an example board of colored notes and, on larger screens, a flowchart and a code block. The canvas on a phone, with two notes and a touch toolbar.

Keep the why next to the how.

A list makes you pick one order too early. Here a question can sit beside the flowchart it affects and the code that answers it, so you see the whole problem at once.

Start before you feel ready.

Open the canvas and write. You do not sign up, and the canvas does not send your board to a server. It saves as you work, in this browser.
