You don't want a free alternative to Turbolearn. You want a tool whose questions don't score 57.8 out of 100.

Turbolearn's free plan caps out at roughly 2 hours of lecture audio, 5 quizzes, 1 PDF upload, and 10 chat messages per month, depending on which marketing page you read. Most students hit that ceiling inside the first week of a normal courseload and the plan converts into a $5.99 to $8.99 monthly Pro subscription. Trustpilot complaints document multiple users being charged when they thought they were on a 3-day trial; the company has acknowledged the checkout wording was unclear. So the honest framing is: the free plan exists, but it is calibrated as a sample, not as a working tier. If you came here from that ceiling, you are looking for something free enough to actually drill on every lecture, not the next 1-PDF trial.

Sign up with email on app.jungleai.com, no credit card. Upload a lecture deck, PDF, textbook chapter, or paste a YouTube lecture URL. You get 200 multiple-choice questions in roughly 60 seconds, plus the same source span turned into free-response, case-style, and image-occlusion flashcard formats. You can run a spaced repetition queue, see your weekly league standing, and grow a tree per deck. There is no auto-renewing card on file, because there is no card on file. The paid tier removes a per-account deck cap and adds the Anki .apkg export, but most students never hit the cap.

By running a held-out eval. We picked three documents the generators had not been trained on (a microbiology lecture, an internal medicine deck, and a pharmacology PDF), generated questions from each with the four major slide-to-quiz tools in the market, and scored every output blind on four criteria: factual correctness, clarity, distractor quality, and question-type coverage. The exact same three documents and the exact same rubric for every tool. Studyly came out at 81.3 of 100. Unattle scored 78.0. Gauntlet scored 68.0. Turbolearn scored 57.8. The full breakdown is in Jungle's internal admin Quality Comparison panel (April 2026). Numbers on a screenshot are not a benchmark; held-out eval scores are.

Most of the gap is on distractor quality and question-type coverage. Turbolearn tends to generate stems that are factually fine but pair them with distractors a competent student rules out in one read (a synonym of the right answer plus two obviously wrong items), so the question stops being a discrimination task. It also leans heavily on one or two question shapes per document instead of mixing recall, application, image-occlusion, and case-style stems. The pre-output gate that catches both failure modes is what Studyly's generator runs before any question is shown, and what raises the rubric average from the mid-50s to the low-80s.

Read the Trustpilot reviews for the specific tool you are considering, sorted by lowest rating, and look for the words 'trial' and 'charged'. The pattern that hit Turbolearn users was a checkout flow that read as a 3-day trial but billed at signup. The pattern that hit several other tools in this category is a free plan that silently expires into a paid one. Studyly's free tier does not collect a card, so neither failure mode is reachable. Paid is opt-in by going to the upgrade screen and entering a card yourself.

Yes for PowerPoint, Keynote, PDF (lecture handouts, scanned textbook chapters, study guides), and YouTube lectures. The transcript step on a YouTube lecture takes a minute or two longer than a slide deck. Raw mp3 lecture audio is the one format we are slower on, an upload is fine but the transcript step adds time. For class recordings, students typically grab the YouTube version of a recorded lecture instead.

Zero, with one footnote. Your Turbolearn-generated quizzes do not transfer (Turbolearn does not export); you regenerate from the same source documents on Studyly, which takes 60 seconds per deck. The footnote: if you were on a paid Turbolearn plan, cancel before the next billing date. Studyly does not import a card and does not auto-renew because there is no auto-renew on a free tier with no card.

Two honest ones. First, if you only need note generation from a single audio recording per month and that's it, the free plan is enough for the demo use case. Second, if Turbolearn has shipped a specific feature you depend on that Studyly does not have (a specific integration with a school LMS, a specific chat-with-document UX), use Turbolearn for that workflow. For 'I want to drill practice questions out of my professor's slide decks for the semester', the eval is the eval; Studyly is the call.

When a Studyly question reappears in a study session, the stem is reworded by an LLM pass and the four options are reshuffled before it is shown. The underlying fact and the topic-pin stay the same. The point is to stop you from pattern-matching the first three words of a question on the second pass, which is the failure mode of every free flashcard app once you've seen the deck twice. Turbolearn's quizzes do not reword on revisit; the same stem with the same options is what you see on the third encounter, which is roughly the moment lazy memorization wins over real retrieval.

Studyly is the marketing surface for Jungle (jungleai.com), the underlying app where the question generator, spaced repetition queue, weekly leagues, and tree-per-deck visualizer live. Jungle has over a million active students across med, dental, nursing, pharmacy, vet, and PA programs, with roughly 7,000 new student signups per week. The product was founded in February 2023 by David Glass and Julian; the MCQ generator and gamified trees shipped in spring 2024.
