The notes app built for handwriting, Saber, is designed to be as simple and intuitive as possible while still delivering unique features that you'll actually use. Available across all your devices—large and small—Saber syncs between them seamlessly, ensuring your notes are always at your fingertips.

One of Saber's standout features is its ability to invert your notes when you're in dark mode. This allows you to write with white ink on a black background, making it much easier on the eyes in low-light environments, such as when the teacher turns off the lights during class. Images and PDFs are also inverted, so you can still use a digital printout or a textbook without any fuss.

Saber takes security seriously with a dual-password system that protects your notes from anyone but you, even if they have complete control over the server. You can safely store your notes on the official Saber server, another server, or even host your own! The app is completely open-source, allowing anyone to view the source code and understand exactly what it's doing and how it handles your data. Unlike many other note-taking apps that are closed-source and proprietary, Saber's transparency ensures you know exactly what you're dealing with.

For those who study mathematics, Saber addresses common frustrations with highlighting multi-line equations. Unlike other apps where the highlighter changes color when it overlaps itself, Saber's highlighter uses canvas compositing to render highlights consistently with—or better than—traditional paper. This means it handles overlaps perfectly and maintains color consistency, making your notes clear and easy to read.

Saber offers robust organization tools. Create folders inside folders inside folders to your heart's content with no limit on the number of nested folders. Even if a note is deeply buried within a nested folder, you can still access it easily, as your most recent notes are always available on the home screen.

Discover a whole new way to capture and organize your thoughts with Saber. Whether you're a student, professional, or creative mind, Saber is your trusted companion for digital handwriting. Download now and let your ideas flow freely!
