What does 'Only returned X of Y requested items' mean?

The AI sometimes returns fewer words, pages, or questions than you asked for — often to avoid duplicates or keep content kid-safe. The results you get are still fully usable: edit them in the preview, add more manually, or run Generate again.

What do Easy, Medium, and Hard cryptogram presets do?

Easy reveals 8 letters and shows the substitution key. Medium reveals 3 letters with the key. Hard reveals no letters and hides the key table. You can also override revealed letters (0–26) manually.

How does the AI cryptogram generator work?

Type any topic — like 'friendship', 'history quotes', or 'Christmas' — and AI instantly creates themed quotes ready to encrypt as a cipher puzzle.

What kind of cipher does the puzzle use?

A classic substitution cipher — each letter is consistently replaced by another. Solvers crack it using letter frequency and pattern recognition.

Are the cryptograms printable as PDF?

Yes. Download a print-ready PDF in A4 or US Letter with a substitution key and answer page. Black-and-white friendly and ink-saving.

Can I edit the AI-generated message?

Yes. Every quote is editable before export — perfect for tailoring to your event or unit.

Can I create a multi-page cryptogram pack?

Yes — generate up to 20 themed pages at once for full puzzle books and party packets.

Does it work on mobile and Chromebook?

Yes. The cryptogram maker runs in your browser — no app required.

Is this worksheet maker really free to use?

Yes — start without a credit card. Manual mode is always free to use and does not spend AI word credits. On the free plan you get 5,000 lifetime AI words (one trial per network), up to 10 PDF downloads per day, and a subtle eduzuma.com watermark on exports. Basic, Pro, and School plans remove the watermark, lift daily limits, and include a commercial resale license.

Do my PDF downloads have a watermark?

Free-plan and guest PDFs include a small eduzuma.com footer watermark. Paid plans (Basic, Pro, School) deliver 100% watermark-free PDFs — the upgrade most teachers and KDP publishers choose.

Is there a daily download limit?

Free and guest users can download up to 10 PDFs per day (tracked in the app). Paid plans include unlimited daily downloads.

Can I sell worksheets or puzzle books commercially?

Classroom and personal use are included on the free plan. Selling on Teachers Pay Teachers, Amazon KDP, Etsy, or similar requires Basic, Pro, or School — each includes a royalty-free commercial license and watermark-free PDFs.

Does using AI cost anything?

Manual mode never spends AI word credits. AI generation uses credits from your plan — 5,000 lifetime words on the free trial, then monthly refills on paid plans.

Can I download multi-page worksheet packs on the free plan?

The free plan exports one page per generation. Basic supports up to 5 pages per click; Pro and School support unlimited multi-page packs — ideal for workbook sets, puzzle books, and full classroom packets.
