Comparison
Fabulè vs Kindle's Ask this Book
In short: Ask this Book is built into the Kindle iOS app and, by default, answers using information up to your current reading position, though you can also ask about the entire book. Fabulè, instead, limits the context to the text you have already read. If you read eligible English ebooks on Kindle for iOS in the United States, Amazon's feature may be all you need. For print books, other formats or other languages, Fabulè is the alternative.

02
The biggest constraint: the book has to be in the right place
Ask this Book lives inside the Kindle ecosystem: it uses the app's reading position to answer within the context you choose. It is convenient if the eligible book is already on your Kindle. Fabulè separates how you read from how it accesses the text: you can search for the title in the archive, scan the QR code on participating books or upload your own EPUB. If you read in print or in another app, you type the last four or five words you read; if you read directly in Fabulè, your reading position is detected automatically.
03
What changes for authors and publishers
With Fabulè, publishers decide whether to make their titles available in the archive. An EPUB uploaded by a reader stays for personal use: the text is not distributed to other readers or used to train models. Participating publishers receive aggregated, anonymous reading data. For Ask this Book, by contrast, the Authors Guild reports that authors and publishers cannot opt their titles out of the feature.
04
Why not just use ChatGPT
ChatGPT, like other general-purpose assistants, does not automatically know the actual text of the edition you are reading or how far you have got. Unless you give it both, an answer about the plot or characters may be inaccurate or reveal something you have not reached yet. Fabulè uses your reading position to limit the context to the text you have already read.
