Connect Instinct to your WhatsApp

Instinct can read your chats, and reply if you allow it. You do not paste a password. You sign in in the browser and pick your number.

Each WhatsApp number is 8 USD a month.

  1. 1Copy the message below.
  2. 2Send that message to Instinct.
  3. 3When it asks you to sign in, a Relay.chat page opens. Use the email on your account.
  4. 4Choose your WhatsApp number, and whether the assistant can only read or also send. Then tap Allow.
  5. 5On a phone, ask the assistant for a pairing code. It shows the code in the chat. Then: WhatsApp, Linked devices, Link with phone number. The code lasts about a minute. On a computer, scan the QR on the Relay.chat page.
  6. 6You can disconnect it later from My account. The same limits still apply: no lists, and a cap on new conversations.
