Questions & Answers

As answered by people managing Diffee and FlexLearnAI.

How would you describe the primary audience of your product?

FlexLearnAI's answer:

Exam-focused students and self-learners who study from their own notes and textbooks — 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.

What makes your product unique?

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 — 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.

Why should a person choose your product over its competitors?

FlexLearnAI's answer:

• No manual setup — it builds questions from your material instead of making you create decks (Quizlet, Anki) • Adapts to you: finds your level in ~5 questions and targets your actual weak spots, unlike static question banks • Spaced repetition built in, so you retain instead of cram-and-forget • Free to start, Pro just $20/mo — cheaper than most exam-prep tools
