Hi. I can tell you what QuanterLab is, what you can do here without an account, and where to start. Ask anything.
The lab is a canvas of cards and wires, made for a desk. Send yourself the link and open it on a computer: every study you read on the site runs there, no account needed.

External Claude clients (Desktop, Code, claude.ai) that have an active OAuth connection to your QuanterLab account. Revoking forces the app to re-authenticate.
Heads-up: clicking "Disconnect" inside Claude.ai's own UI does NOT reach this server — the token survives on our side until you revoke it here or it expires (30 days). Use the per-row Revoke buttons or the "Disconnect everything" button below for a real disconnect.
