TurboLearn vs Turbo AI: is it the same app?
Yes. TurboLearn AI shortened its name to Turbo AI and moved to turbo.ai. Its rebrand page says accounts, data, mobile apps and pricing stayed the same, and old turbolearn.ai links redirect automatically. Reviews and videos that mention TurboLearn are describing the same product, so everything on this page applies to both names.
Is Turbo AI (TurboLearn) free?
You can start for free, but we cannot quote its paid prices. Turbo AI's website invites you to start for free and did not list plan prices when we checked on August 3, 2026; paid plans are shown inside the app. Check the offer there before you rely on the free tier for a whole semester.
QuerySpark publishes its numbers: a 3-day Pro trial with no card, then a free plan with 1 study session, 20 questions, 20 flashcards, 10 PDF pages and 1 YouTube video a month. Student is $9 a month, or $7 a month billed yearly. See the full plan comparison.
Recording lectures vs uploading what you already have
This is the biggest difference. Turbo AI is built around an AI notetaker that listens to your lecture and writes notes, which you can then review with quizzes and other activities. It also takes PDFs, YouTube videos and your own notes.
QuerySpark does not record class for you. You upload the recording afterwards (audio or video up to 25 MB, transcribed for you), or add the PDF, slides, a photo of your notes or a YouTube link. If you want to turn a lecture recording into a quiz after class, QuerySpark handles it; if you want your phone to take notes during class, Turbo AI is the better tool.
Inside QuerySpark
Start from whatever your course gives you
Upload a file, paste notes, or add a YouTube video, a web article or a lecture recording. QuerySpark turns it into questions, flashcards and a study guide.
Practice questions and remembering what you studied
Both generate quizzes from your material. Turbo AI's site shows multiple choice, fill-in-the-blank and open-response questions and promises practice "until it clicks". QuerySpark makes multiple choice, true/false, short answer and essay questions, explains every answer, and on most questions shows the passage from your material the question came from.
Where they differ is review. QuerySpark schedules flashcards with spaced repetition, brings back missed questions and scores practice tests. Turbo AI's website does not describe a spaced repetition schedule, so if timed reviews matter to you, check inside the app before committing.
Turbo AI vs StudyFetch, NotebookLM and Quizlet
People comparing Turbo AI usually look at these three as well. In short:
- StudyFetch is the closest match: it also records lectures and generates notes, and adds an AI tutor, flashcards with a spaced learning hub and an iOS app. See QuerySpark vs StudyFetch.
- NotebookLM is Google's source-grounded notebook. It is strongest at answering questions across many sources and making audio overviews, rather than taking notes in class. See QuerySpark vs NotebookLM.
- Quizlet is a flashcard platform with a large library of sets made by other students and mature mobile apps. See QuerySpark vs Quizlet.
When to choose each
Choose QuerySpark if…
- You want exam-style question depth. QuerySpark writes multiple choice, true/false, short answer and essay questions at the cognitive level you choose, each with an explanation.
- Retention is the priority. Flashcards are scheduled with spaced repetition and the questions you miss come back, so material sticks past the next lecture.
- You want a published monthly price. QuerySpark publishes a $9 monthly Student price. Turbo AI did not show plan prices on its website when we checked, so compare its in-app offer directly.
- Your inputs are documents, not live audio. If you study from PDFs, notes and slides rather than recording lectures, QuerySpark's document-first workflow is a faster fit.
Choose Turbo AI if…
- Lecture note-taking is your primary need. Turbo AI listens to your lectures and takes notes for you. If that is the core job, it is purpose-built for it and QuerySpark is not.
- You want notes, flashcards and quizzes in one pass. Turbo AI generates several study activities from a single lecture, which is convenient for class-heavy schedules.
- You study on your phone. Turbo AI has a mobile app that stays synced with the website. QuerySpark runs in the browser and has no mobile app.
- You want ready-made AP material. Turbo AI offers a library of pre-made AP study guides and books. Its website does not document Bloom-level targeting or LMS exports.
