There are three major players in the digital notebook space—Boox, reMarkable, and Supernote—but this year, a new challenger popped up and quickly emerged as a contender: Viwoods. With the help of a kickstarter, the startup launched its first product earlier this year, the Viwoods AiPaper, a 10.65-inch e-ink notebook that touted itself as an AI-forward productivity device.

I was skeptical—nothing pings my radar quite so much as selling your product solely on its AI features—but I came away impressed. Right out of the gate, Viwoods produced one of the best digital notebooks on the market, and right now, you can pick one up for $80 off for Black Friday.

Great specs and smart software

The AiPaper has a Carta 1300 display, the most recent e-ink screen and the same one you’ll find on a Kindle Paperwhite, with a resolution of 2560 x 1920 and 300ppi. The matte screen has a slightly textured quality that makes the writing experience feel pleasantly tactile with the recently upgraded Viwoods EMR stylus.

The device is powered by an unspecified 2GHz “octa-core” processor with 4GB or RAM and 128GB of onboard storage, which is on par other e-ink notebooks. The 4,100mAh battery should last about a week with regular use. At 4.5mm thick and weighing around 370g, it’s easily portable without feeling flimsy or insubstantial.

Actually useful AI integration

The AiPaper has a little “Ai” button on the bottom bezel. Press it, and you can start a conversation with ChatGPT. Each native app also has an onscreen version of the same button that offers several options:

• “Analyze content” sends a screenshot of whatever is onscreen to ChatGPT, which will describe or summarize it.

• “Generate an email” will attempt to turn whatever is onscreen into a message that you can then copy into your linked email app of choice with a tap.

• “AI text conversion” will turn your handwriting into copyable text and describe any images along the way

• “AI assistant” opens the chatbot and attaches a screenshot of whatever is on the display

• “Customize” allows you to craft your own frequently used AI prompts so you don’t have to type them every time

I’m pretty impressed with the way Viwoods has implemented its AI integrations. Dropping the AI into every program makes it much simpler and more cohesive to use, assuming you are the kind of person who likes to use AI for everything. (I’m not.)

E-reading and apps, too

App integration means you can also use the AiPaper as an e-reader, either using the native document reader or your reading app of choice—with a little setup, you can load most any app from the Google Play store. The crisp, responsive screen makes it a pleasant Kindle alternative, and the large display shows off black and white comics and manga quite nicely.

How long do Black Friday deals really last?

Black Friday sales officially begin Friday, November 28, 2025, and sales run throughout “Cyber Week,” the five-day period that runs from Thanksgiving through Cyber Monday, December 1, 2025. But Black Friday and Cyber Monday dates have expanded as retailers compete for customers. You can get the same Black Friday sales early, and we expect sales to wind down by December 3, 2025.

Does Amazon have Black Friday deals?

Yes, Amazon has Black Friday sales, but prices aren’t always what they seem. Use a price tracker to make sure you’re getting the best deal, or refer to guides like our live blog that use price trackers for you. And if you have an Amazon Prime membership, make the most of it.

Are Black Friday deals worth it?

In short, yes, Black Friday still offers discounts that can be rare throughout the rest of the year. If there’s something you want to buy, or you’re shopping for gifts, it’s a good time to look for discounts on what you need, especially tech sales, home improvement supplies, and fitness tech. Of course, if you need to save money, the best way to save is to not buy anything.
