Major Differences

Kindle Unlimited is an independent digital reading subscription service provided by Amazon, which allows readers to access its extensive library of millions of books with a monthly subscription fee. In contrast, Prime Reading is simply one part of the Amazon Prime membership, which means it is not exclusively designed for online reading, and the number of accessible books is much less than the Kindle Unlimited. However, you must keep in mind that, the list of titles is rotating every month, new titles will be added to Prime Reading and some titles will be gone, which you will not get bored of the same materials.
