What are the best tools for making coloring, puzzle and other low-content books for KDP?
Book Bolt combines niche research with KDP-sized cover and interior design and puzzle generators. Tangent Templates is a $59 one-time alternative for interiors and covers, Puzzle Maker Pro builds puzzle books in volume on Windows, and Inkscape is a free way to draw line-art pages. AI coloring generators such as ColorCraft also work, but KDP requires AI images to be disclosed.

- States a commercial license that covers books sold on KDP
- Price published on the vendor's page

Considered, not picked
- KDPEasy: Covers and interiors in one place, but its Chrome extension saves drafts inside your KDP account, which carries terms-of-service risk.
- Book2Color: Free-tier images cannot be used commercially, and the service is new (domain registered January 2026).
- KDP Coloring Book Studio: Its cost claims come from a comparison page the vendor publishes about itself; we could not verify them independently.
