Gridly reads your textbook content and generates publication-ready crossword puzzles in seconds — complete with answer keys, clue lists, and printable layouts. Study material becomes a game your students actually want to play.
No bloat. No feature creep. Just the tools teachers actually asked for.
Upload a textbook chapter in PDF, DOCX, or plain text. Gridly identifies key terms, definitions, concepts, and relationships — the building blocks of a great crossword puzzle.
Our algorithm arranges extracted terms into a properly interlocking crossword grid, writes contextual clues from the source material, and balances difficulty for your selected grade level.
Download your puzzle as a print-ready PDF with a clean student worksheet, a separate answer key, and an optional clue bank. Ready for the copier in under a minute.
The best review tool is one that doesn't feel like review. When students race to fill in a crossword grid, they're studying — they just don't know it yet.
We measure what matters: puzzles that actually get used.
Priya Sharma spent years creating review materials for her science classes — crosswords, word searches, matching activities — all by hand. Every new chapter meant hours of layout work that had nothing to do with teaching.
Gridly was born from a simple idea: if the textbook already contains the terms and definitions, a computer should be able to turn them into a puzzle automatically. It turns out it can, and teachers have been asking for exactly this.
Gridly is free during the open beta. Upload a chapter, generate a crossword, and print it before your next class. No account setup required to try it — just drag and drop.
