You can't fix what you can't see.
The most dangerous feeling before an exam is confidence you haven't earned. You've read the chapter, reviewed your notes, and everything feels familiar — but familiarity and mastery are not the same thing. Until you try to explain a concept from memory, you don't know if you actually know it.
Learnlo makes the invisible visible. A 10-minute AI-graded practice exam reveals exactly where your knowledge holds up and where it falls apart — concept by concept, before the real exam finds out for you.

Frequently Asked Questions
How does Learnlo identify knowledge gaps?
After you take a written-answer practice exam, the AI grades each answer against the concepts it extracted from your material. Each concept gets a mastery percentage. Concepts below ~60% are flagged as gaps.
Is this just a quiz with right/wrong answers?
No. Learnlo generates written-answer questions — the kind you actually face in exams. The AI grades your answers with partial credit and gives specific feedback on what was missing from each response.
How is this different from just testing myself with flashcards?
Flashcards test recognition (seeing the card and saying "I knew that"). Learnlo's written-answer exam tests recall — producing an explanation from memory, which is a much stronger signal of real mastery and closer to actual exam conditions.
Can I retake the exam after studying my gaps?
Yes. Plus and Pro plans include adaptive follow-up exams that specifically target the concepts you scored lowest on. It's a targeted re-test, not a repeat of the same exam.
What subjects work best for this?
Any subject with concepts that can be explained in writing: sciences, medicine, law, history, social sciences, computer science, and more. The AI adapts to the vocabulary and structure of your specific material.
Does it work with handwritten notes?
Yes. Upload an image of your handwritten notes and Learnlo will extract text, identify key concepts, and build the practice exam from your actual notes.
What is the difference between Free and Plus for knowledge gap analysis?
Free users see a summary of their weak topics. Plus users get the full concept mastery breakdown with percentages, specific feedback per concept, and adaptive follow-up exams that target the gaps.
