Frequently Asked Questions
Is PuzzleForge really free for KDP publishing?
Yes — 100% free with no watermarks, no account, and no restrictions on commercial use. You can publish puzzles generated here on Amazon KDP or anywhere else.
How do I save my puzzles as a PDF for KDP?
Click "Save PDF" after generating. A clean print window opens — in Chrome or Edge choose "Save as PDF" as the printer. The PDF saves at the exact KDP page size you selected.
How does the AI word generation work?
PuzzleForge uses a Bring Your Own Key (BYOK) model. You supply your own API key from a provider like Google Gemini, OpenAI, or Anthropic Claude. Your key is stored only in your browser's memory for the current session and is permanently deleted when you close or refresh the tab. You are responsible for your own API usage and costs. If you don't have a key, the built-in word bank works great.
How many puzzles can I generate at once?
Up to 50 unique puzzles per session. All export in one PDF with answer keys at the back — ready for KDP upload.
What KDP page sizes does PuzzleForge support?
8.5×11 inch (standard letter), 6×9 inch (digest — most popular for activity books), and 5×8 inch (small format). Select before generating.
How is PuzzleForge different from BookBolt?
BookBolt is a paid subscription. PuzzleForge is completely free with no subscription and no watermarks. PuzzleForge runs entirely in your browser — nothing is sent to our servers and your content stays private on your device.
Do I need an account to use PuzzleForge?
No account required. Open the page, configure your puzzle, and generate. No email, no sign-up, no login.
Can I use my own word lists?
Absolutely. Paste any words into the custom word box, one per line or comma-separated. Or choose from 20 built-in categories with 600+ curated words. Mix both if you like.
