Viwoods AiPaper: Specs, Features, Pros & Cons
Viwoods left the front light out of the AiPaper, and that one decision shapes who should consider it. The 10.65-inch Carta 1300 screen reads well in daylight or under a desk lamp and not at all in a dark bedroom. Supernote made the same call on its large writing tablet: one fewer layer between the pen tip and the ink, in exchange for a device you cannot use with the lights off.
The AiPaper is the largest of four Viwoods devices. The AiPaper Mini adds a light on a smaller screen, and the two AiPaper Reader models are pocket readers for books. Viwoods is a young Hong Kong brand, so buying one is a bet on a small company's software team as much as on the hardware.
What separates it from the closed writing tablets is the software. It runs Android with the Google Play Store, so third-party reading apps and cloud drives such as OneDrive can sit next to Viwoods' own notebook, planner and meeting apps. A dedicated AI key below the screen opens an assistant that takes a spoken or typed request, and it can work from the current page, a text selection or a circled drawing.
The box includes the magnetic stylus and a folio case. Some rivals sell the pen separately, so the bundle closes much of the gap to cheaper tablets once their pen is added, and the AiPaper sits with the upper-middle e-ink note tablets on price.
Besides the light, it gives up clarity about the pen. Viwoods lists no pressure-level or latency figures on its own site, and its specification page there carries at least one typo, so the manual and the product description are the documents to trust.

Editor’s note
The missing front light is the first thing I would weigh. If most of your writing happens at a desk, in meetings or on a train in daylight, it costs you nothing. If you read in bed, this is the wrong tablet, and the AiPaper Mini, which has a light, is the Viwoods to look at instead.
The hardware is well judged for the size. At 4.5 mm and 370 g it is closer to a paper notebook in the hand than to a 10-inch Android slate, and a 300 PPI panel is as sharp as monochrome e-ink gets in this class. Battery life is the soft spot. Viwoods itself quotes about a week at two hours a day, which is modest for e-ink and reflects the Android system underneath. If you write every day, plan on a weekly charge.
The AI assistant leads Viwoods' marketing, and I would treat it as a bonus rather than a reason to buy. It runs on outside models (the manual names GPT-4o and DeepSeek), so it needs a connection and your page leaves the tablet when you use it. Viwoods says there is no fee for it. A small company can change that, and the AiPaper still has to earn its place as a notebook without it.
Android 13 is an older base by now. Play Store access keeps the door open for reading apps, but I would not count on major version upgrades from a maker this size.
Against the Supernote Manta, the choice is Viwoods' Android flexibility and bundled pen versus Supernote's quieter, closed system and longer record of updates. I would buy the AiPaper for PDF markup and meeting notes in good light, and pass on it for reading at night. The 60-day trial and 14-month warranty make the gamble on a young brand smaller.

The bottom line
The Viwoods AiPaper earns a VS Score of 44, below the median of the 13 E Ink note e ink tablets it is measured against (a score of 50 is level with that median).
- Who it’s for
- Someone who marks up PDFs, takes meeting notes and keeps a planner at a desk or in daylight, and wants Android apps next to the note software without buying the pen separately.
- Who should look elsewhere
- Anyone who reads in bed or in dim rooms, because there is no light of any kind. Look elsewhere too if a long software track record matters, since Viwoods is a young brand.
- The trade-off that matters
- Dropping the light keeps fewer layers over the ink, but it makes the AiPaper a daylight and desk-lamp device, which rules it out for many evening readers.
- The main alternative
- Supernote Manta, a large unlit writing tablet with a closed, distraction-free system, for people who want notes without Android or AI features.
