What is OwlU?
Owlu is a vertical-domain AI email assistant that delegates email handling to AI, returning results in real-time to the user interface. Its core mission is to provide solo pros with a completely free smart email assistant—no paid subscriptions required, and no hidden fees for any feature. Users can aggregate and manage all their accounts—including Gmail (23 messages), Outlook (89 messages), Naver Mail (147 messages), corporate email (31 messages), and custom domain email (18 messages)—all within a single interface. The inbox currently displays a total of 290 unread emails. The tool prioritizes security: it uses Google OAuth authentication and Apple Notarized installation packages, explicitly stating, “Your emails will never leave your control.” During login, only OAuth 2.0 authorization is used; the tool neither accesses nor stores email passwords.
Key features
Automatic categorization of newsletter emails: Automatically identifies and archives weekly newsletters from sources like Marketing Weekly, such as “[Newsletter] 5 marketing trends this week,” with one-click classification and archiving;
Smart extraction of meeting details: Automatically parses key information—such as time, location, and attendees—from meeting invitation emails and adds it directly to your calendar. For example, it can structurally extract details from emails like “Are you free for a meeting next week? Would Tuesday at 2 PM at our office work…” sent by Nathan Cole.
