Technical explainers
Write the explainer. Draw the diagram. Publish both.
System design, algorithms, machine learning: the best explanations mix prose, equations and a drawing. Octonote AI keeps them side by side and publishes them as one page.
How it works
Start a project
A project is one note and one canvas in a split view — writing on the left, drawing on the right.
Drag figures into the text
Group shapes into a figure and drag it into the note by its title. Edit the drawing later and the note updates.
Publish and share
One click gives you a public page with your byline, a heading minimap, upvotes and view counts. Readers can switch between note, split and canvas.
Real examples
Questions
Who is this for?
Engineers, educators and creators who explain technical topics on YouTube, LinkedIn, newsletters or blogs and want one link that holds both the write-up and the diagram.
Can my AI agent write the first draft?
Yes. With the octonote CLI, Claude Code or Codex can create the note from markdown and draw the canvas from a Mermaid flowchart, then you edit and publish.
Do readers need an account?
No. Published pages are public and read-only; signing in is only needed to upvote.
