| Software update 5.20.2 introduces "Ask This Book," which acts as an interactive reading companion. |
Amazon has officially begun rolling out Kindle software version 5.20.2, and it's packing a feature that many users have been waiting for since last December. The headline addition is "Ask This Book," an AI-powered reading companion that has been available on the Kindle iOS app for nearly a year, but is now finally making its way to dedicated e-readers.
For those unfamiliar, Ask This Book acts as an interactive assistant that can answer questions about plot points, characters, and other details from the book you're currently reading. The feature is accessible through the search function or by highlighting a word or passage. Once activated, you can ask questions and even follow up on previous answers, making it feel like a conversation with a well-read friend who's always up to speed on your current read.
One of the smarter aspects of this feature is its spoiler-control functionality. When starting a new chat, users can choose between "reading so far" or "full book" mode. The former restricts answers to content you've already covered, keeping you safe from accidental spoilers. The latter, as you might expect, opens up the entire book and comes with a note warning that insights may include spoilers.
A Massive Download
According to Notebookcheck, the 5.20.2 update is among Amazon's largest firmware files to date, weighing in at approximately 643 MB. That's a hefty download, so if you're on a limited data plan or slow connection, you may want to plan accordingly.
How to Know If Your Book Supports It
Not every Kindle book is compatible with Ask This Book just yet. According to The eBook Reader Blog, the feature only works with selected Amazon-published or distributed ebooks. If you want to check whether your current read supports it, simply open the book and look at the search icon in the top menu. A small "+" symbol will appear on top of the search icon when Ask This Book is available.
The Limitations You Should Know About
Before you get too excited, there are some important caveats. First and foremost, an internet connection is required to use Ask This Book—it's not an offline feature. Second, sideloaded titles and Send-to-Kindle documents are not supported, which means your personal library of non-Amazon content won't benefit from this functionality. Finally, not all Amazon books are supported yet, so you'll need to check on a book-by-book basis.
Rollout Details and Compatibility Questions
The 5.20.2 update is currently being pushed out automatically to compatible devices. Interestingly, Amazon hasn't listed the download on its official Kindle Software Updates page yet, and no release notes have been published. This lack of transparency has left some compatibility questions unanswered, particularly for 2024 models like the Kindle Scribe. However, users of the recently launched 2026 Kindle models should receive the update without issue.
The absence of the update on Amazon's software page is part of a concerning trend. As noted by The eBook Reader Blog, the last three Kindle updates haven't appeared on the official update page, and Amazon still hasn't added any of the new 2026 models to that page—despite the new Kindle being out for nearly a month. This has led to speculation about whether Amazon plans to stop offering manual downloads and updates altogether.
Community Reaction
Over on the r/kindle subreddit, users have been discussing the update and its implications. Some, like a user named CJ, expressed skepticism about whether it's worth updating a jailbroken device, noting that recent Scribe updates haven't offered much in the way of useful features. Others, like retired IT professional Charles, take a different view: "I always do the updates as there are always security patches that protect the devices."
For those looking to pick up a new Kindle or check out compatible accessories, you can browse Amazon's Kindle selection to see the latest models and recommendations.
What's Next?
With Ask This Book now on dedicated e-readers, Amazon continues to blur the line between traditional reading and AI-assisted interaction. Whether this feature proves genuinely useful or remains a novelty will likely depend on how well it handles the nuances of different books and genres. For now, if you've received the 5.20.2 update, it's worth trying out on your next read—just make sure to select "reading so far" if you're spoiler-averse.
