ReaderScout is a free Chrome add-on developed by ReaderScout. It falls under the category of Browsers and is classified as an Add-ons & Tools program. With ReaderScout, users can receive notifications when Amazon books receive new reviews or undergo price changes.

This program offers several useful features for book enthusiasts and authors. It displays the follower count of an author and provides the current ABSR (Amazon Best Sellers Rank) of each tracked book. By checking for updates on Amazon every twenty-four hours, ReaderScout ensures that users are quickly alerted to any changes found.

Using ReaderScout, users can save time by avoiding the need to regularly check books for updates. The program allows users to react promptly to negative reviews, take advantage of price opportunities, and stay informed about new positive reviews as they arrive in the store.

Please note that ReaderScout is currently limited to 50 books per author due to operational costs. However, the goal is to keep ReaderScout free so that more authors can benefit from its services and protect themselves against Amazon spammers.

ReaderScout is currently available only for Amazon US, but the development team is actively exploring options to make it available in international markets in the future. For more information and help with setting up ReaderScout, users can refer to the tutorial provided on the ReaderScout website.
