A Smart Pen is a digital writing tool that captures handwritten notes and drawings. It typically uses special paper or a digital surface to record what you write in real-time. The pen often connects to devices like smartphones or tablets via Bluetooth, allowing users to save and share their notes easily. Many Smart Pens come with features such as audio recording, which syncs with your notes, making it easier to review lectures or meetings. Some popular brands include Livescribe and Moleskine, which offer various models tailored for different needs, from students to professionals.
