About Knowbotic
Knowbotic is a USMLE Step 1 question bank aimed specifically at international medical graduates, and its entire positioning is price. The established Step 1 banks cost several hundred dollars for a subscription window; Knowbotic sells the same shape of product — 20,000+ exam-style questions across 32 specialties, each with a full worked explanation rather than just a correct-answer flag — at $19 a month or $190 a year. The study loop is browse by exam, then subject, then topic, filter by difficulty and question type so you only see what is on your blueprint, answer with instant right/wrong plus the reasoning behind it, and then convert any topic into a timed, scored, exam-style test that reports a percentage and what you missed. Seen-question tracking runs across the whole bank, so sets stay new until the entire library is worked through, which is a meaningful detail in a category where accidental repetition inflates practice scores. An AI question generator supplements the fixed bank — the free trial includes ten generations a day — so a weak topic can be drilled beyond the bank's coverage. The free tier is a genuine trial rather than a teaser: twenty real bank questions with full explanations, no card, plus access to the public library. Paid access is metered in bank questions per month (1,000 on the yearly Exam Pro plan) rather than sold as unlimited, which is the main thing to check against your own study volume before committing. Support is email, prioritised on the paid tier. There is no claim of official USMLE affiliation.
