Ship a Kanban board to production.

The 20-minute tutorial that converts the most readers into power users. You describe a board, the agent provisions Postgres, builds drag-and-drop with optimistic state, wires up auth, and deploys to your own subdomain. Ends with a real URL you can share with your team before lunch.

The fastest learners are already shipping.

A handful of readers who took a tutorial and turned it into something they actually use.

The Kanban tutorial was my first real touch with the agent. By minute 18 I had a working board with drag-and-drop. I forwarded the URL to my team before I closed the tab.

I picked up the Universal Key tutorial during lunch and replaced four provider SDKs in our backend by the end of the day. The drop-in OpenAI compatibility is the whole pitch.

I am not a developer. I followed the internal-ops tutorial and replaced our scheduling spreadsheet with a real app over the weekend. My team thinks I went to a bootcamp.

The agent works best with a real idea. Skip the tutorials, ship your project, come back when you need a specific recipe.
