A note-taking app that digitizes handwriting on paper. Reborn as the dedicated application for Neo Smartpen: Neo Studio 2! Experience the improved Neo Studio 2 with a more convenient and streamlined note-taking environment, expanding the handwriting paradigm. #Introduction of Main Features [Page View] Now you can scroll through the timeline with a single page view. You can easily check your handwritten notes without entering a detailed page. [Text Extraction] The previous 'Handwriting Recognition' function has been renamed to 'Text Extraction.' It has also been changed to a button at the bottom right of the handwriting detail page, allowing you to instantly convert your handwritten content into text. [Lasso Tool] In the handwriting detail page, you can select specific areas with the Lasso Tool for text extraction or to share only the selected area. [Split] Now overlapping handwriting is automatically separated. This addresses the issue of choosing the right time of overlapping notes, allowing you to isolate them and then automatically separate into the same notebook as the first writing. [Connect Only This Pen] If other smart pens are on, they may automatically connect to the app, but now you can focus on one pen, adding this feature to boost concentration. [Synchronization] Synchronization is now done in real-time without manual intervention, so you can log in with your existing account on any device, and your handwritten data will be reflected automatically.
