## Common questions

**Are these tools free?**

Yes. Every generator makes its page in your browser, with no sign-up and no watermark. It is free for classroom, home and personal use.

**Do the puzzles come with answer keys?**

Yes. Each puzzle prints as two pages: the puzzle on page one and a full answer key on page two, so it is easy to check. Journals and planners are page templates, so they have no answer key.

**Which tool makes journals and planners?**

Use the lined paper generator for lined, dot grid, graph and guided journal pages, and the printable calendar for planner months. The KDP cover calculator sizes the wraparound cover once you know your page count.

**Can I sell books made with these tools?**

The free tools make one page or puzzle at a time for personal and classroom use. To make a book you can sell on Amazon KDP, Publisher Studio generates hundreds of puzzles and builds journals and planners as print-ready 300 DPI PDFs.
