Saber is a free, open-source, cross-platform notes app built for handwriting with a stylus or finger. It offers encrypted note sync across devices, PDF annotation, a non-overlapping highlighter, and dark-mode note inversion.

Use cases

• take handwritten notes on a tablet
• annotate pdfs with a stylus
• sync handwritten notes between phone and laptop
• read notes comfortably in dark mode
• organize notes into nested folders
• encrypt notes so even the server can't read them
• highlight text without the highlighter changing color

When to choose

• you want a free, open-source alternative to OneNote or GoodNotes
• you need handwriting notes across Android, iOS, Linux, Windows, and macOS
• you want end-to-end encrypted note sync or self-hosted sync
• you annotate PDFs and lecture slides by hand

When to avoid

• you need plain-text or markdown note-taking with wiki links
• you require collaboration or real-time multi-user editing
• you need OCR or handwriting-to-text conversion
• you want a web-only app without installing anything
