Compiled October 2026 from Hidden Gems's public pricing and documentation. Features and prices change - verify current details on their site before deciding.
Hidden Gems asks you to book a date, holds it with a non-refundable deposit, and warns that its calendar fills months in advance. With ArcRoster you send to your own team when the book is ready - useful when a release date moves.
A 50-reader Hidden Gems order is $140, and you pay again for the next book. ArcRoster is a flat plan - Free, then $7, $17, or $39 a month - and every reader on your roster can be invited to every launch.
Every reader you approve keeps their history in your CRM, with a reliability score from how often and how promptly they review. Each launch starts from readers you already know rather than a new team.
Hidden Gems matches your listing to readers who like your kind of book, across most commercial genres plus several nonfiction categories. If you don't have readers yet, that matching is real value ArcRoster doesn't offer.
Hidden Gems states plainly that it does not guarantee review counts or star ratings, and bills only for readers who actually sign up. It publishes an average review rate of over 80%, and in one documented romantasy launch about 60% of its readers reviewed.
ArcRoster is in public beta, and there's a free plan to start on. Bring your reviewers, run your next campaign, and see who actually shows up.
