Knowable launches AI tutor Milo with camera-based, step-by-step hints

Knowable, an education app from developer Samuel Xu, is available on the App Store for iPhone, iPad, Mac and Apple Vision, requiring iOS 17.0 or later. Its AI tutor, Milo, uses the camera to read a problem and offers hints based on the user's current progress instead of giving the answer. The app includes a Test Prep mode that generates practice problems from uploaded course materials, with 1,000 free credits per month and 10,000 credits per month on subscription.

This product positions an AI tutor around in-process hints rather than replacing teachers or outputting answers, which is relevant for parents and teachers assessing the role of AI tutoring tools. Its progress-based hints and course-material-driven practice directly affect how students use it for self-study and exam prep, while the teacher shared link and parent-controlled sharing define the data boundary between classroom and home. The developer's statements about images not being stored and on-device voice processing are its own claims; the App Store page notes privacy information is not verified by Apple, so actual data handling still depends on the privacy policy and later independent checks. Students can receive step-by-step hints while working on paper, reducing answer-copying use. Teachers and parents can use the shared link and sharing controls to decide what learning content is synced.
