A developer built a journaling/note-taking app that combines handwritten thought structuring with Claude interactions. Users create notes by handwriting on a tablet, and Claude writes back on the page to explore ideas together. It supports PDF/ebooks annotation, allowing Claude to generate notes from selections and discuss or quiz the user. The app will be released soon, runs on Android tablets with a stylus, and can be ported to iPad.
