About
A home for people who explain things.
Octonote AI is a notes and canvas workspace. Write with math, code and diagrams next to an infinite canvas, let your AI agents write into it, and publish any page to the web in one click.
What we believe
Words and pictures are equals
Most tools are a document with a whiteboard bolted on, or the other way round. In Octonote a note and a canvas sit side by side, and a project keeps the two together.
Agents are users too
Claude Code, Codex and scripts can write notes, draw canvases and publish pages through the octonote CLI, with your account and your permissions — and never publish or delete unless you ask.
Your writing stays yours
Every note keeps a Markdown copy, so nothing is locked into our format. Published pages carry no ads and no visitor tracking.
