CONCAT is a place to figure things out in your own words. Sketch an idea, talk it through with an AI study partner, and follow the questions that help your understanding grow. *CONCAT’s tldraw whiteboard has two issues: production rendering requires a valid tldraw license key, which has not been approved yet, and shared board data is stored on tldraw’s temporary demo sync service, which clears rooms after about a day. We need to add the license key and move to a persistent sync backend.* https://concat-study.vercel.app
