Everything educators want to know before uploading their first chapter. If your question isn't here, email us and we'll add it.
Gridly accepts PDF, DOCX, and plain text (.txt) files. You can also paste content directly into the editor. During the beta there is no file size limit, though chapters under 50 pages produce the best results since the term extractor can focus on a coherent set of vocabulary.
Yes. Gridly has been tested across biology, history, literature, chemistry, geography, economics, psychology, and dozens of other subjects. The term extraction engine adapts to different writing styles and discipline-specific vocabulary. If the chapter contains identifiable terms and definitions, Gridly can build a puzzle from it.
Gridly supports content from elementary school through university level. When generating a puzzle you select a target grade band — K–5, 6–8, 9–12, or higher education — and the clue writer adjusts language complexity and hint style accordingly.
Our clue accuracy rate is currently 94%, measured by teacher review during the beta. Every clue is generated directly from the uploaded source material, not from general knowledge, so it reflects what your students actually read. You can edit any clue before exporting if you want to adjust the wording.
During the open beta, Gridly is completely free for all educators. There are no usage limits, no premium tiers, and no credit card required. After the beta we plan to keep a generous free tier for individual teachers. Pricing for school-wide or district licenses will be announced separately.
Uploaded chapters are processed to extract terms and generate puzzles, then deleted from our servers within 24 hours. We do not store, share, or use your content for any purpose other than generating your puzzle. See our Privacy Notice for full details.
Yes. After generation you can add or remove terms, rewrite clues, adjust the grid layout, and change the difficulty level. You can also regenerate the entire puzzle with one click if you want a completely different arrangement of the same terms.
Gridly exports puzzles as print-ready PDFs (student worksheet plus answer key), PNG images, and shareable digital links for online completion. The PDF is formatted for standard letter-size paper and prints cleanly on any copier or printer.
You can try Gridly without an account — just upload a chapter and generate a puzzle. Creating a free account lets you save puzzles to your library, track which chapters you've covered, and access your puzzles from any device.
No. Gridly is a teacher-facing tool. Students interact only with the printed or shared puzzle — no student accounts, no student data collection, no tracking. If a student completes a puzzle via a digital link, no personally identifiable information is collected or stored.
Gridly puzzles are designed as study aids and review activities, not formal assessments. While many teachers use them as low-stakes quizzes or homework assignments, the crossword format is best suited for vocabulary reinforcement and concept review rather than graded examinations.
