Circles

What is Circles

Circles is a connector that links your personal WhatsApp to AI assistants like Claude, ChatGPT, Instinct, and any AI that supports MCP or an API. It allows your AI to read, search, and reply in the chats you choose, similar to how you might already connect your email to an AI. Circles works by connecting as a linked device to your WhatsApp account, without requiring any software installation on your phone.

How to use Circles

1. Connect your WhatsApp: Type your number, then scan a QR code or enter a code in WhatsApp's Linked devices (like WhatsApp Web). Confirm from the one message Circles sends to that WhatsApp.
2. Connect your AI: Link Claude, ChatGPT, Instinct, or another AI in one step each.
3. Ask your AI about WhatsApp: Ask questions as usual. Your AI will read, search, and reply in the chats you allow.

FAQ

Do I need a credit card?
No. Your first 14 days include every chat, then 2 chats are free until 3 months from linking. A card is only required when you choose Plus or Pro.

What happens when Free ends?
Your AI stops reading, and your chats are retained for 14 more days. Choose a plan to restore full access.

How much history does my AI see?
All available history in the chats you allow, on every plan: what WhatsApp shares when you link, and everything that arrives after.

Will my AI send messages as me?
Yes, in chats where writing is enabled. You can turn off writing in any chat, and every message sent by your AI is logged in your activity log.

Which AI does it work with?
Claude, ChatGPT, Claude Code, Instinct, and any AI that connects through MCP or the API.

Can WhatsApp disconnect my number?
Circles connects as an unofficial linked device, which WhatsApp's terms do not authorize, so disconnection is possible. Circles mitigates this by never broadcasting, sending one message at a time, and using a dedicated IP for each account.
