Messaging-App AI Intern Assistant

Sell solo founders an AI intern that lives in WhatsApp—voice notes become tasks, CRM updates and drafts.

In plain English

Solo founders can message an AI helper in WhatsApp, iMessage, or Telegram the way they would message an intern. A voice note or a text can become a task, an update to their customer records, or a draft such as a newsletter. They can start free and move to a paid yearly plan when they want more, because a founder still needs those chores captured. The AI does most of the message reading, the record updates, and the billing. The person running the product still does a real share of the work, connecting other tools, helping users, and talking with founder communities.
