Optim API
FlexLearnAI is an AI-native study coach that converts your own material into adaptive practice. Upload a PDF, textbook, notes doc, or EPUB and it extracts the concepts, generates practice questions, and calibrates your level in the first 5 questions. From there it targets difficulty to your ability, tracks which concepts you've actually mastered, and schedules spaced-repetition reviews so nothing slips before your exam. Unlike static flashcard apps, every quiz is generated from your source material and adapts in real time. Students use it for SAT and ACT prep, NCLEX, professional certifications (PMP, CPA, AWS), college exams, language learning, and technical training. Free to start โ upload a document and run your first practice session without paying. Meet Flexo, the coach that studies with you.

FlexLearnAI's answer
Exam-focused students and self-learners who study from their own notes and textbooks โ nursing students (NCLEX), high schoolers (SAT/ACT), college students, and professionals earning certifications (PMP, CPA, AWS). Time-pressed learners who want study time that actually sticks.
FlexLearnAI's answer
Most study apps make you build flashcards by hand (Quizlet, Anki) or drill a generic, pre-made question bank. FlexLearnAI turns your OWN notes, PDFs, or textbook into practice questions automatically โ then adapts to you: it pins down your level in about 5 questions, keeps targeting the concepts you actually keep missing, and uses spaced repetition to resurface weak spots right before you'd forget them. It's a tutor's adaptivity built on your material, not someone else's deck.
