Leave a trail — free AI practice test maker
Every student walks into an exam like walking into a forest. Upload a PDF, Word file or photo of your study guide or past exam, and AI turns it into an online practice test — auto-graded, shareable, free forever. The test you leave behind becomes a path for someone in your school next year.
University students use it to prep for finals — Philosophy, Political Economy, Macroeconomics… Teachers use it to turn paper exams into digital ones. Every test stays public, searchable, and free.
Making quizzes with AI — what you gain, what you lose
What you gain with LOSAN
- ✓ Quizzes from your own material: Lecture notes, study guides, slides — AI writes questions scoped to the course you are about to sit
- ✓ Automatic grading: Online exams grade multiple-choice and even essay answers instantly
- ✓ Share by link: Send the link to classmates and revise together, on any phone
- ✓ Images preserved: Diagrams, graphs and formulas are kept intact by AI
What you face with the old way
- ⚠ Rereading the study guide: It feels familiar, until the exam shows you what you actually got wrong
- ⚠ Entry mistakes: Hand-typing slips questions, miskeys answers, loses diagrams
- ⚠ Exams stuck on paper: Paper exams cannot be taken online or auto-graded
- ⚠ Not reusable: An exam authored once and never stored as a reusable bank
Tips for better AI quizzes
1. Shoot clear, well-lit photos
Sharp photos help AI read every question and formula correctly.
2. Check before saving
Preview the built exam and fix any slips before saving and sharing.
3. Use the source file when possible
An original Word or PDF file gives more accurate results than a photo.
Why make practice tests with AI?
Testing yourself is the most effective way to revise, but writing questions from a study guide takes an afternoon. AI does it in seconds, so you spend your time on what matters: answering, seeing where you slipped, and revising exactly that.
