Worksheet Cleaner vs Exam Creator

Worksheet Cleaner turns a photo of your worksheet into a clean blank original — ready to print, practice, or solve again. HOW IT WORKS 1. Photograph the sheet, scan it, or import a PDF 2. The app crops the sheet automatically 3. Tap "Clean" 4. View the result, save, print, or export as PDF THE SHEET STAYS THE ORIGINAL • No generative AI image model. The sheet is never redrawn — printed text, lines, boxes and illustrations stay pixel-for-pixel intact. That is exactly what redraw-style apps cannot do. • Every pen colour is detected, not just pencil: ballpoint, felt tip, marker. • Export the result as PDF, print it, share it, or keep it in the archive. HOW DETECTION WORKS • To find the handwritten areas, the app sends a downscaled copy of the sheet to our server. Only coordinates come back — no text, no edited image. • The removal itself runs on your device. • The copy is not stored; we do not pass it on for AI training. • Cleaning therefore needs an internet connection. Viewing, printing and exporting sheets you already cleaned works offline. EXTRAS • Multi-page scan into one document • Subject auto-detection from worksheet content • Textbook recognition via ISBN scan • Student profiles (multiple kids, separate histories) • Choose where files are stored: on the device or in any folder you pick, including iCloud Drive • Spotlight search across all saved documents • iPhone, iPad, and Apple-Silicon Mac PRIVACY • No login, no account, no ads, no tracking • Cleaned sheets and student profiles stay on your device or in the folder you picked yourself • Only the downscaled image copy is transmitted, for detection — no name, no account, no advertising ID • Full privacy policy in the app and at https://www.worksheet-cleaner.com/legal/cleaner-datenschutz.html SUBSCRIPTION • 2 free pages within a 5-day window per installation • Then Premium: up to 100 pages per month on the monthly plan, up to 300 pages per month on the yearly plan (fair use) • Apple shows the current local price before purchase • If Apple shows an introductory offer, it is available once per Apple ID • Auto-renews, cancel anytime via your Apple ID • Required Apple disclosures at the bottom of this description PLEASE NOTE Detection can miss handwritten areas or mark too much.

An exam-writing and typesetting tool for STEM teachers — and for students building their own practice papers. The questions, the exam paper and the PDF are all produced on your iPhone or iPad. Typesetting Is Built In The app carries a complete LaTeX typesetting engine and the fonts it needs, so it still sets a paper as an A4 PDF in airplane mode. Equations, tables, answer grids, headers and footers, a long proof that runs across a page break — the typesetting engine lays all of it out. Nothing here is a web page printed to PDF. A Question Bank You Reuse Questions live in the bank, filed under six levels: domain, subject, course, chapter, section, topic. Filter them by difficulty, question type, tags, source, academic year, or which paper they have already appeared on. This year’s paper is next year’s starting point: duplicate it, swap out a few questions, leave the rest. Questions From Your Own Material Paste your key points, import a PDF, or photograph the board or your own handouts. PDFs and photos are sent once, at import, to the AI service you chose, which reads them; the app then splits the text that comes back into passages on the device, retrieves what fits, and writes questions from that. Each question records the document and the page it drew from, so you can check it on the spot. Solutions Generate solutions only for the questions that do not have one, or redo a single question on its own — changing one question does not mean paying for the whole paper again. The solutions can be in a different language from the paper, and you can add a standing instruction of your own, such as “end each one with the mistake students usually make”. Sixteen Languages Traditional Chinese, Simplified Chinese, English, Japanese, Korean, German, French, Spanish, Portuguese, Italian, Dutch, Polish, Russian, Turkish, Vietnamese, Indonesian. The header wording printed on the paper follows. Before export, the app checks that the fonts can actually draw every character on the paper. If one is missing, the export stops and names the character and the question it sits in. It does not print blanks. Handoff to AI Grader Pro The exported PDF carries four alignment squares and a QR code on every page, and the answer region coordinates are measured while typesetting and written into the file. AI Grader Pro crops straight to them and grades. Your Data Stays Yours No account, no cloud sync. The AI features use your own API key, and the key is kept in the system Keychain on this device. You can also point the app at an Ollama or LM Studio you run yourself, in which case nothing leaves your own network. Without AI, nothing needs a network: picking from the bank, writing your own questions and typesetting the PDF all happen on the device. Only the AI features go online — importing material sends the PDF or photos you attach, and generating sends the request for questions. Subscription Writing questions, the question bank, typesetting, and the full preview are free and unlimited. The only thing that needs a subscription is taking the finished paper out — saving it as a PDF, printing it, or sharing it. The subscription comes with a 14-day free trial. Pro Monthly · Pro Yearly Your local price is shown in the app and on this page. The subscription renews automatically until you cancel it in your App Store account settings. Renewal is charged within 24 hours before the period ends. Questions are still generated with your own API key, and the provider bills you for that directly, as it always has. The subscription does not cover those charges. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
