Hi. I can tell you what QuanterLab is, what you can do here without an account, and where to start. Ask anything.
Manage your account and subscription.
If you created this account with Google, it has no password yet. To set one, sign out and use Forgot your password? on the login page; the link comes to this address.
We'll send a confirmation link to the new address — your email changes only after you click it.
A once-daily summary of your live paper trades. You can also unsubscribe from the footer of any digest email.
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.

To connect a new client, see Connect to Claude.
The Agent lens inside Quantin uses a server-side connection to call QuanterLab MCP tools on your behalf. This is independent from any external Claude client you've connected above. Pause it here to disable the Agent lens for your account — the MCP cell in the Quantin footer goes red "Unavailable".

Quantin runs on Haiku for free across every lens (paid by QuanterLab). To use Sonnet or Opus in any lens, paste your own Anthropic API key — tokens are then billed to your Anthropic account, not the platform.
Important: this is an Anthropic API key from console.anthropic.com, NOT your Claude.ai login. The two are separate billing surfaces — a Claude.ai Pro subscription does NOT grant free API access.

Deleting your account locks you out immediately and stops all live paper trades and emails. Your data is then permanently erased within 30 days. To confirm, type your email address below.
