Saber

Saber is a cross‑platform note‑taking application designed for stylus input and typed text. It lets users import images and PDF files into their notebooks, and it stores notes in a hierarchical folder structure that can be nested without limit. The app includes a highlighter that avoids overlapping strokes and changes color when retraced, while rendering beneath the text for clear readability.

All notes are encrypted end‑to‑end, ensuring that only the user can read them; the synchronization service can the data across phones, tablets, and computers without exposing the content to the server. A cohesive dark mode extends the dark theme to the note canvas itself, reducing eye strain when working in low‑light environments.

Saber is released under an open‑source license, with its source code publicly available on GitHub. It is listed as stable and intended for individuals who need handwritten or typed notes that can be organized, highlighted, and securely synced across multiple devices.
