Frequently Asked Questions
- Does Supernote support EPUB files natively?
- Yes. Supernote A5X and A6X2 support EPUB, PDF, MOBI, and TXT natively through the built-in reader. EPUB files open with reflowable text, adjustable font size (5 levels), and three text spacing options. Supernote does not run Android, so you cannot install third-party apps — all reading and annotation happens through the Supernote reader, which is clean and focused.
- How do I transfer an EPUB to my Supernote?
- Three methods: (1) USB — connect with the supplied USB-C cable, the Supernote appears as a drive; drag your EPUB to the Document or Book folder; (2) Supernote Cloud — sign in at supernote.com and upload via the web interface; files sync over Wi-Fi when the device connects; (3) Supernote Partner App (iOS/Android) — connect the app to your Supernote via the same Wi-Fi network and push files wirelessly.
- What makes the Supernote stylus unique compared to reMarkable and Kobo?
- Supernote uses a ceramic-tipped stylus (Heart of Glass) that wears against the screen surface over time to create increasing friction — mimicking the feel of pen on paper as you use it more. Unlike WACOM-based styli (reMarkable, Kobo Elipsa), no charging is required. The Supernote A5X stylus has a flat-back design for natural pen grip. The writing latency is very low and the feel is distinctive among e-ink writing tablets.
- Can I annotate EPUBs on Supernote?
- Yes. Supernote supports freehand annotation on EPUBs — tap the pen icon to enter annotation mode and write directly on the page with the stylus. You can also bookmark any page and add starred highlights to key passages. Annotations are stored within the Supernote book record and can be exported as a PDF with your handwritten notes embedded, via the Supernote app or cloud export.
- How does Supernote compare to reMarkable 2 for EPUB reading?
- Supernote A5X vs reMarkable 2: both have 10.3-inch e-ink displays (Supernote: 227 ppi; reMarkable 2: 226 ppi). Supernote has a frontlight; reMarkable 2 does not. Supernote supports EPUB natively without firmware updates; reMarkable 2 required firmware 3.0 (2023) for EPUB support. Supernote has a more focused, distraction-free OS; reMarkable 2 now has some smart features. Both have excellent stylus feel; Supernote's ceramic tip is distinctive. Price is similar (~£350–400).
