Question: I'm looking for a smartpen that can digitize my notes and sync them across multiple devices.

If you want a smartpen that can digitize your handwriting and synchronize it across multiple devices, Livescribe is a great choice. Its smartpens record handwritten notes and accompanying audio with an infrared camera and special dot-patterned paper. The Livescribe+ app synchronizes notes across devices, converts handwriting to text, and supports multiple cloud services for sharing. It's great for taking notes in meetings, lectures and brainstorming sessions.

Another contender is XNote, which uses a special notebook and smart pen to digitize your handwriting. The system integrates with ChatGPT for conversational dialogue with notes, has AI-powered task detection with reminders, and works in 53 languages. It also has cloud storage, sharing and export abilities, making it a full featured tool for note-taking and organization.

If you prefer a more app-based approach, Goodnotes offers a more natural handwriting experience with AI-powered features like spell check and word completion. You can combine handwritten and typed text, edit PDFs and record audio, and search to find specific notes. It's a flexible tool good for students, teachers and professionals trying to improve their note-taking productivity.
