Prose drifts. The moment there's a branch, the AI improvises and loses the thread, and you're never sure it ran the way you meant.

One diagram, one source of truth. Hit ▶ on a process and paste the prompt into your AI. It starts at the start, follows the arrows, and takes the right branch every time.

Yours, in every sense.

How it works

The same diagram a person reads, an AI runs. Here's a real one on the canvas:

A 1canvas process named Analysis: Start, then read a document on notion.com, then compare it to a document on google.com, then a diamond asking 'is it the same?'. Yes leads to End; No leads to a step that sends an alert message on slack.com.

Your first runnable process is minutes away.
