FAQ
Q: How does the Smart Dark Mode function during writing sessions?
A: The Smart Dark Mode is designed to be visually comfortable by allowing you to write with white ink on a dark, eye-friendly background. It intelligently adjusts your workspace so that you can switch between lighting environments without experiencing eye strain or needing to manually change your pen colors.
Q: Will my imported documents look strange when I switch to dark mode?
A: Not at all, because Saber utilizes dynamic inversion. This technology automatically detects imported PDFs and images and adjusts their appearance to match your dark background, ensuring that your reference materials are as legible and comfortable to read as the notes you write yourself.
Q: How does the highlighting feature avoid the messy overlapping colors found in other apps?
A: Saber utilizes advanced canvas compositing to ensure a premium experience. This technique mimics real-world stationery, meaning your highlights will never fade or create messy, opaque color overlaps.
