Portend has no chatbot of its own — instead, it plugs into the AI you already use. Connect once and your assistant can log predictions, revise your odds as your view shifts, and check your calibration with you.
Your connector URL

Claude (claude.ai, desktop, or mobile)
Go to Settings → Connectors → Add custom connector, paste the URL above, and click Add. Then enable it in any chat from the + menu.
Other assistants
Any client that supports remote MCP connectors works — look for "connectors," "integrations," or "MCP servers" in its settings and paste the same URL.
Your AI will open a Portend authorization page. Sign in with the same account and click Approve. That's it — your assistant only ever sees your predictions, and you can revoke access from your AI's connector settings anytime.
Tip: in Claude, the connector also adds ready-made prompts — look for Capture a prediction and Calibration review in the + menu.
