An exam-writing and typesetting tool for STEM teachers — and for students building their own practice papers. The questions, the paper and the finished PDF are all produced on your device.

WORKS WITHOUT A NETWORK
The LaTeX typesetting engine is inside the app. No connection, no desktop, no LaTeX installation. The sample paper typesets in about three seconds, so a finished exam takes minutes — on a train, in a staffroom, anywhere. (Writing questions with AI, or importing material, needs a connection.)

A QUESTION BANK THAT LASTS
Save every question you write into a categorised bank: domain, subject, course, chapter, section, topic, difficulty, type and tags. Search it, re-open a question, edit it, and reuse it. Next year you do not start over.

REAL MATHEMATICS
Write mathematics as LaTeX and see it rendered as you type. Fractions, integrals, matrices, AMS symbols, tables and figures all typeset properly, in a serif face made for print.

A PAPER THAT LOOKS LIKE A PAPER
Set the masthead — school, course, exam name, date, marks. Choose per-question answer space in centimetres. Print questions and answer space together, or split the paper into a question sheet and a separate answer sheet that students hand in on its own.

EXPORT AND SHARE
Preview the PDF, then save it to Files, print it, or share it. Solution keys export as PDF and as LaTeX source. Papers and question banks export as a portable file you can carry to another device.

AI IS OPTIONAL, AND USES YOUR OWN KEY
Writing an exam needs no AI and no key at all — the bank, hand-written questions and PDF typesetting work as they are. If you do want AI to draft questions or write worked solutions, you supply a key for a provider you already have an account with: OpenAI, Google Gemini, any OpenAI-compatible endpoint, or a model you run yourself with Ollama or LM Studio. Requests go from your device straight to that provider. We never see your key and never proxy your content, and that provider bills you separately.

Always review generated questions and solutions before giving them to students.

YOUR WORK STAYS YOURS
No account, no sign-in, no server of ours. No analytics, no crash-reporting, no advertising and no tracking. Your question bank and papers live on your device.

HANDOFF TO AI GRADER PRO
Every page carries alignment marks and a QR code, and answer regions are measured while the paper is typeset — so AI Grader Pro can crop straight to each answer when it grades.

SIXTEEN LANGUAGES
The interface follows your device. The paper's language and the solution language are chosen separately, so an English class can still get solutions in another language.

FREE AND SUBSCRIPTION
Writing questions, typesetting, previewing and the bank are unlimited — make as many papers as you like. A subscription is for the last step: saving, printing or sharing the PDF, and the first fourteen days are free. The subscription does not include AI usage.
