Penpal, the AI assistant that lives in your inbox

Field notes

Penpal uses an email thread as both the interface and the conversation history: users send a question or forwarded message to hi@askpenpal.com, then reply to continue. The homepage demonstrates the pattern with a phishing check involving the lookalike domain netfl1x-billing.com and says the service can be used from Gmail, Outlook, restricted workstations, or older connected hardware. It states that three replies per day are free, with 50 more available for $5.
