Why Studio
Built for the print pipeline.
Studio isn’t just a puzzle generator. It ships every artefact a real production workflow needs — from KDP-safe layouts to a manifest your build process can read.
- KDP-safe layout presets — KDP 6×9, 8.5×8.5, A4, Letter, or custom dimensions
- Manifest JSON with every puzzle's ID, settings, and license info
- Custom puzzle ID format (e.g. PZL-001, BOOK-1-A)
- Print-ready PDF, PNG, and SVG — bundled in one ZIP download
- Optional answer-key PDF in matching layout
- Configurable typography — separate digit + text font sizes, margins, gutter, bleed
- 1, 2, 4, or 6 puzzles per page
Choosing the right tool
How Studio compares.
Studio is built specifically for self-publishers and small publishers who need professional output without the design overhead. Here’s where it fits in the landscape.
| Alternative | Strength | Where Studio fits |
|---|---|---|
| Dedicated desktop generators (e.g. Crossword Compiler) | Comprehensive, established crossword tooling | Studio is web-based with no install, focused on Sudoku and Nonogram, modern UX, and ships SVG plus a manifest JSON out of the box — better suited to self-publishers who want professional output without the learning curve of full-featured desktop software. |
| Free online generators | Free, easy to find | Most free generators have unclear or restrictive commercial licensing, no batch generation, and produce PNG-only output. Studio is purpose-built for publishers: royalty-free commercial license, batch generation, KDP-safe layouts, and SVG for print. |
| DIY (Python scripts, custom code) | Full control, no cost beyond your time | Studio replaces the engineering work — no code to write, no edge cases to debug, no PDF layout to wrestle with. Production-ready output in minutes instead of weeks of iteration. |
| Manual layout in Word, InDesign, Canva | Familiar tools, full design flexibility | Studio handles puzzle generation, layout, and matching answer keys automatically. Use Studio for the puzzle interior and a design tool of your choice for the cover, or wait for Studio's upcoming cover designer. |
