Amazon's Kindle line looks increasingly lonely between updates. While e-readers are far from the favored consumer electronics trend of yesteryear, retail powerhouse hasn't lost its focus on the category either: after all, according to estimates, Amazon controls more than 80% of the U.S. market.

Alongside the much-awaited color Kindle, Amazon has announced a refresh across the line. Among those are updates to the base Kindle, Kindle Paperwhite, and the stylus-enabled Kindle Scribe.

It was only a matter of time before Amazon added AI to the line, and so the first recipient of honors is the Kindle Scribe. Building on the largest Kindle's note-taking features, Amazon is adding text summaries, thanks to a new notebook tab. The device will automatically clean up messy text scribbled using the Premium Pen stylus while making it legible but appearing like script.

The Scribe's design language has undergone a bit of an evolution, with white borders but a resolution that reads 300 ppi. The device will gain a new feature on its side panel: the ability to write and hide notes when needed.

The new Scribe will run $399 — that's a $50 premium over its predecessor's already steep price tag.

The bestselling Kindle Paperwhite sees a jump in display size from 6.8 inches to a full seven inches. Meanwhile, the process is increasing in speed with Amazon promising 25 percent faster paper turns. Amazon says the battery life of the device is rated at a substantial three months on charge, even with the thinner design.

The reader is getting the same new oxide back pane found in the Colorsoft device, which allows for those faster page turns, while increasing overall battery life.

The regular Paperwhite includes 16GB of storage and runs $160. For a further $30, you can get the Signature Edition, including 32GB of storage, wireless charging capabilities, and an auto-adjusting front light.

The second change brings the base Kindle inline with the Paperwhite set to max: it enables faster page turns, a better contrast ratio, and a 25 percent brighter front light. It comes in several colours, including a new "matcha" green. The entry-level reader will cost $110.
The entry-level Kindle reader and Kindle Paperwhite are up for order today, with the Scribe arriving December 4.
