Getting lost in a long novel because you can't remember who a minor character was or when a certain key detail was mentioned is quite common. Until now, the quickest solution was usually to open your browser, search for the character's name, and cross your fingers that you didn't stumble upon a massive spoiler in the first line.
With that scenario in mind, Amazon has begun rolling out a new AI-powered reading assistant on Kindle called “Ask This Book .” Its goal is simple yet ambitious: to allow readers to ask questions about the book they are reading and receive an instant answer, without leaving the app and, above all, without revealing events that haven't yet occurred in the story.
A reading assistant who knows the book (and your progress) in detail
Amazon's proposal is based on a very specific concept: each compatible title has its own specialized reading assistant . This isn't a generic chatbot like those used on the web, but a tool focused exclusively on the content of the book you have open on your Kindle.
The company describes it as having an expert on the work in front of you, available at any time to answer your questions. This “digital expert” understands the plot, characters, setting, and main themes of the text, and can answer both general and very specific questions, always within the limits of what you have already read.
The key to the system is that the artificial intelligence strictly respects your reading progress . Even though it has access to the entire book to analyze it, it only generates responses based on the chapters and pages you've already read. If you're still on chapter three, it won't tell you what happens in chapter ten, even if you ask it indirectly.
According to Amazon, this "spoiler-free" behavior is designed precisely to avoid one of the most common problems with external searches: discovering plot twists or endings ahead of time when trying to clarify a seemingly innocent doubt.
In addition to tracking your current position, the assistant takes into account the immediate context of what you're reading. This allows it to offer explanations that fit the current scene , rather than simply providing generic definitions or summaries detached from the narrative.
What can you ask "Ask This Book"?
The range of queries this function supports is quite broad. The idea is that you can use it when you get lost in a series , when you pick up a book again after months of not reading it, or when you need to clarify details about the setting or relationships between characters without having to reread entire pages.
Among the examples that Amazon itself provides and the most common use cases are questions such as:
- About the plot up to the present point: “What happened in the last few pages?”, “Why is the protagonist angry with his brother?” or “In what era does the story take place?”.
- About the characters and their relationships: “Are Oliver and Amy married?”, “How do these two characters meet?” or “What is this character’s relationship to the protagonist’s family?”.
- About the world and the context"What was happening in the world when this story takes place?" or "What historical conflict is mentioned in this chapter?"
The answers, the company explains, must meet three basic requirements: they must be immediate, stay within the context of the book, and not include spoilers . It's not an external encyclopedia, but rather an explanation anchored in the text you've already read.
A practical example Amazon uses to illustrate how it works is a novel that includes the phrase "Mr. Collins' offer." If the reader doesn't remember exactly what that offer referred to, they can select the phrase and click "Ask ." The system will then suggest a question—for example, "Explain this"—and, upon accepting it, will generate an explanation of the offer based on previous chapters.
From there, the reader can continue conversing with the assistant: the tool allows for follow-up questions related to the same scene or character, turning the experience into a kind of contextual chat about the book, without disconnecting from the reading.
How to access the function within the Kindle app
In practice, access to "Ask This Book" is integrated into the Kindle app in two different ways. First, you can access the assistant from the book's menu , where the specific option for this feature appears. From there, an interface opens where the reader can freely type their questions.
Alternatively, and perhaps more naturally, the function can be activated by highlighting a confusing section of text . After selecting a phrase or paragraph, the user sees the option to ask the AI, which often includes predefined query suggestions (“What does this mean?”, “Remind me who this character is”, etc.).
Once the conversation begins, a history of questions and answers is generated and remains associated with that book and that reader . It is not a public forum or a shared space: the clarifications remain on the device and are intended as personal support, not as content that can be freely distributed.
Amazon also emphasizes that responses cannot be copied or exported directly from the app. This is intended to prevent them from becoming automated summaries that could be distributed outside the Kindle environment, which would be particularly problematic in terms of copyright.
Regarding supported titles, the company mentions "thousands of books" in English that already have this assistant active. Not all eBooks in the store have the feature, as the system requires a specific preparation and review process for each title to ensure reasonably reliable performance.
Current limitations: territory, language, and devices
Currently, "Ask This Book" is in a limited rollout phase. The tool is only available in the United States , specifically within the Kindle app for iOS devices. This currently excludes both Kindle e-readers and those using the app on Android phones and tablets.
Amazon has announced its intention to bring the assistant to other platforms over the next few years . Its roadmap specifically includes the move to Kindle e-readers and the Android app, which the company anticipates will happen around 2026. If these timelines are confirmed, the result would be a more seamless experience across devices.
Regarding Europe and countries like Spain, there is currently no official date or detailed communication . Everything suggests that Amazon's initial priority is to consolidate the feature in the US market, refine the quality of the responses, and expand the catalog of compatible books in English before moving into other languages.
For the feature to be meaningful in Spanish, the company will have to adapt its AI models to Spanish-language books and work with European and Latin American catalogs. It's not just a matter of translating the interface, but also ensuring that the responses respect cultural nuances, idiomatic expressions, and specific narrative styles found in works by Spanish-speaking authors.
Until then, Spanish readers can only follow the assistant's development from afar. Many are wondering to what extent it will change the way they approach long sagas, fantasy novels with dozens of characters, or dense technical books , where any extra help to avoid losing track is usually welcome.
A useful feature for readers, but controversial for authors and publishers.
From a purely user's perspective, the tool might seem almost perfect for those with a terrible memory when it comes to long books : contextual help, quick answers, and no major spoilers. However, the reception in the publishing world has been considerably cooler.
The main reason is a decision by Amazon that has generated concern: authors and publishers cannot opt their works out of "Ask This Book." Company spokespeople have explained to specialized media outlets, such as Publishers Lunch, that the feature is activated by default for compatible titles and that there is no opt-out mechanism.
From the company's perspective, this policy aims to maintain a consistent reading experience across the entire catalog: if a reader becomes accustomed to using the assistant in several books, it wouldn't make sense for a specific book to suddenly not offer the same assistance. However, for much of the publishing industry, this means that book content is being used to feed an AI system without the rights holders having any say in the matter.
The debate comes at a particularly sensitive time. Several media outlets and organizations have sued artificial intelligence companies for the way they use copyrighted works to train language models. Without going into technical details, Amazon's initiative adds another layer to the discussion: to what extent is it acceptable to process entire books to offer a reading assistant, even if the responses are limited to what the reader has already purchased or rented?
The company attempts to alleviate some of these concerns by reminding users that access to the feature is restricted: only those who have purchased or borrowed the book can use the assistant, and always within the closed Kindle environment. Furthermore, the answers are based on specific passages from the book and cannot be shared directly, which, in theory, limits the risk of the system becoming a substitute for the book itself.
Even so, many observers see this decision as yet another example of how major tech players tend to deploy AI applications first and debate their legal implications later . In this case, the balance between reader convenience and creators' control over the use of their texts is once again being tested.
Kindle recaps: summaries to keep up with the sagas
Alongside the "Ask This Book" assistant, Amazon has introduced another tool designed for those who devour lengthy sagas or book series and need a refresher before continuing. These are Kindle Recaps, which generate summaries of previous installments to make it easier to revisit the story.
The idea is similar to the classic "previously on..." feature in television series: before starting a new volume, the reader can consult a recap of the plot, character arcs, and key events from the previous book. This reduces the need to reread individual chapters or jump from page to page looking for clues.
To use these Kindle recaps , users simply access the series' page in their Kindle library and tap the "View Summaries" button. From there, they can view the summaries generated for each title in the collection. This feature is available on Kindle devices and the iOS app, and is planned to expand to other platforms.
With this approach, Amazon aims to support the reader at two key moments: first, by helping them remember the essentials just before resuming a saga , and then, while progressing through the new book, with the timely help of "Ask this book" when something doesn't quite fit.
However, the company urges caution: as with any AI-generated content, inaccuracies or nuances may appear that aren't fully reflected in the summaries. In fact, Amazon has previously been forced to remove an automated "Video Recaps" feature due to quality issues, suggesting that it will continue to refine these text tools based on real user feedback.
These new features paint a picture of a more interactive and algorithm-driven e-book , but without replacing traditional reading. Those who prefer can completely ignore these functions, while those who easily get lost among characters, plots, and subplots now have extra support to avoid abandoning complex stories due to disorientation.
Between readers who appreciate having a "book expert" just a tap away and a publishing industry uneasy about the use of its catalogs in AI systems, the new Kindle assistant occupies a complex middle ground. What is clear is that, if it eventually arrives in Europe and is adapted to Spanish, it will change the way many readers interact with their eBooks , while simultaneously forcing a rethink of how rights are managed and how authors and publishers participate in these types of tools.
