Is ChatGPT AI for WhatsApp messages by MailMagic safe?

Clean risk

ChatGPT AI for WhatsApp sends your chat text and the other person's name to MailMagic's servers to draft an AI reply.

When you use the AI reply feature, the extension reads the currently open WhatsApp Web chat: the visible message text, the contact's name, and your own profile name/email. It sends this to MailMagic's backend, which forwards it to an AI model to generate a suggested response, and separately archives the conversation context and generated reply on MailMagic's servers tied to your account.

Shared hosts - 3 hostnames

Hostnames hardcoded in this extension that few other listings call. That can mean one operator behind both, and it can equally mean a small shared vendor, so it is context rather than a conclusion. Hosts that many listings call are left out: they are services, not connections.

Where it sends data

Destinations our analysis observed WhatsApp AI contacting. Sending data somewhere is not a finding on its own - an extension that syncs your settings has to talk to its own server - but it is where your data can go, and who else it goes to.
