Every puzzle is checked for exactly one solution, then analyzed using human-style solving logic so difficulty means more than a simple clue count.

  • Unique-solution verification before export
  • Logical difficulty evaluation and quality safeguards

Smart Book Builder

Plan an entire book instead of configuring sets one by one. Enter the quantity you need, choose your audience or progression, review the plan, and apply it in one step.

  • Balanced size and difficulty progression
  • Book presets plus a fully custom plan

Complete Font Studio

Browse installed fonts, explore the live Google Fonts catalog, or safely import an uninstalled font file—with instant previews before generation and PPTX export.

  • Font categories, search, keyboard navigation, and live preview
  • Preview digits, letters, and Roman numerals
  • Resilient fallback when internet or Google Fonts is unavailable
