KDPEasy has no write-up on Specifiction yet; its figures are above.

Librava.ai is a web platform for creating print-ready activity books, educational materials, and low-content books, with files prepared for KDP download. Its book tools cover coloring books, journals, planners, children’s storybooks, covers, and custom interiors. Puzzle generators include Sudoku, word search, crosswords, mazes, Kakuro, Numberlink, and Bridges/Hashi. Librava says generated puzzles are validated before export, and listed logic puzzles are checked for exactly one solution. Exports include PDF and TIFF, with print dimensions and title-text tools. The pricing page advertises commercial licenses and no-watermark paid exports, while the FAQ says users retain commercial rights and may sell books through KDP, Teachers Pay Teachers, Etsy, Gumroad, or their own site. Users download files and upload them to KDP themselves. The service works in modern browsers, including mobile. A free plan allows five watermarked exports monthly; paid plans are billed annually at $122, $163, or $345. Trial duration is described as two or three days in different pricing materials.
