Calibro Sketch: Excalidraw Diagrams for Confluence

Describe a system in a sentence — “a React frontend talks to a Python API, using Postgres and Redis” — and Sketch draws it: real, editable Excalidraw elements, laid out and wired up. The drawing is saved as real content in your Confluence site, and the AI runs on Atlassian-hosted Claude models — nothing leaves your site.

Quick start:

• Pick Sketch in a space’s sidebar. Describe what you’re building and AI draws it — or start blank. It saves as you go.
• Refine from the command bar — add a service, rename a store, put a queue between two boxes. Undo works on everything.
• Click Atlassian object to add live Confluence page cards that read their state at view time — they never go stale.
• One diagram, edited once, current everywhere — embed it on any page by typing /sketch
• In English, German, Spanish, French and Portuguese

Pricing: free for up to 10 users, the whole app, no time limit. From the 11th user, US$0.25 per user per month, billed by Atlassian with your Confluence subscription.
