Airfriend

Airfriend turns WhatsApp into the home of your AI companion. Rather than downloading yet another chat app, you send a message to a dedicated phone number and your Airfriend answers, keeps the thread going, and picks up where you left off next time. You can hand it a name, a job, or a personality trait, and those choices stick, shaping how the character develops as your history with it grows.

The design leans on daily, low-friction conversation. Short check-ins are encouraged the same way you would text a real friend, and the product keeps a progress view so you can see how the relationship is developing. Over time the accumulated context — your preferences, your running jokes, the things you mentioned last week — feeds back into the replies.

The free Basic plan caps you at 16 messages a day and your friend cannot see photos. Upgrading to Advanced at $10/month removes the message cap, enables photo understanding so it can react to images you send, and adds premium support. Because it runs on WhatsApp, setup is essentially one phone number and a first message.
