Libraro

Libraro is a British publishing and manuscript screening platform where authors upload sample chapters, readers read and rate them in a crowd-review format, and the platform turns reading behaviour, completion rates and scores into demand signals publishers can use. Manuscripts are encrypted on submission and timestamped on-chain to evidence date of creation and integrity, and the company says the underlying methods cover more than 16 blockchain patents.

In practice an author submits the first three chapters plus an outline, readers unlock chapters in sequence, and a manuscript that clears a rating threshold enters a publisher recommendation pool; publishers filter by genre, reader profile and feedback keywords, shortening the path from submission to contract. The platform takes a 20% service fee on concluded rights deals, and editors at Hachette UK, Simon & Schuster UK and Bonnier Books UK have publicly commented on the value of its reader feedback data. Manuscripts entering the recommendation pool come with reader profiles and chapter completion curves, which publishers use to judge genre fit and the size of the target readership.
