LacQuiz: AI Exam Prep & Quiz

Upload a PDF, snap a photo of your notes or just type a topic, and AI builds a practice test with explanations in seconds. Free questions every day, no account needed.

LacQuiz is an AI quiz maker for exam prep: it turns your notes and PDFs into practice tests in seconds.

Upload a document, paste your notes, snap a photo of a page or simply type a topic. Choose how many questions you want, the type and the difficulty, and AI writes a test based on exactly what your material covers.

FOUR WAYS TO START

• Documents: PDF, Word, PowerPoint and text files, including scanned PDFs • Photos: take a picture of your notebook, the board or a book page (up to 20 pages) • Pasted text: copy notes from anywhere and paste them in • A topic: type something like "Photosynthesis – Biology grade 12" and practice without any document

KEY FEATURES

• Six question types: multiple choice, true/false, fill in the blank, short answer, 4-statement true/false (the format used in Vietnam's national high school exam) and mixed sets • Easy, medium and hard difficulty • Practice mode at your own pace, or a timed mock exam scored out of 10 • Every question has a short explanation that points back to your material • Results come at the end, so you can focus on answering first • My mistakes: questions you got wrong are saved so you can practice them again on their own • History: every question set you create is saved so you can retake it later • Edit, delete or regenerate a single question • Print a worksheet with the answer key on its own page, or export a CSV file for flashcard apps like Anki and Quizlet • Available in 13 languages; questions are written in the language you choose, even if your material is in another language • Light and dark mode • Free to use with no account: open the app and start

FREE EVERY DAY

You get 20 free questions on your first day and 10 free questions every day after that, renewed automatically. Need more? Credit packs are one-time purchases right in the app, never a subscription; each credit creates one question.

WHO IT'S FOR

• High school students preparing for final exams and end-of-term tests • College students studying for midterms and finals from slides and textbooks • Self-learners who want to check what they remember after reading

PRIVACY

Free to use with no account; we do not collect your name, email or phone number. The camera and photo library are used only when you choose to add photos. Purchased credits are tied to your device; the recovery code in Settings lets you move them to a new phone. The documents and photos you send are processed only to create questions and are not stored long term. Your questions and study history are saved on your own device and can be deleted at any time in Settings.

PLEASE NOTE

Questions are generated by artificial intelligence. They are checked automatically, but they can still contain mistakes. Tests made from a topic come from general knowledge, not from your own textbook, so check anything that looks wrong. You can report any question right in the app so we can improve quality.

An internet connection is needed to create questions.
