Partly: Turbo AI has a free plan for notes, flashcards and quizzes, but it publishes no limits and has no pricing page. You find the cap by hitting it. The paid plan is $20 a month or $120 a year, with no refunds.
Stay on the free plan if you turn the odd PDF or short recording into notes and flashcards, and can live with not knowing where the cap is.
Pay if you record lectures every week, and take the annual plan only if you are sure, because the $120 is charged at once and is not refundable.
Skip it if you study mostly from readings and slides, since NotebookLM takes 50 sources per notebook free of charge and tells you so in writing.

| Pro | not published | Named as a tier in the terms. No price or feature list on any public page |
The free plan covers the core job. Turbo AI's FAQ says it includes note generation, flashcards and quizzes, and that upgrading unlocks "unlimited features". There is no table of limits anywhere on turbo.ai.
The figures review sites print, such as 2 hours of lectures and 1 PDF a month, appear on no official page, so we do not repeat them as fact. What we could confirm is that a cap on lecture hours exists, because the site's own upgrade prompt says so.
Turbo AI states its price in its own blog posts from July: $20 a month billed monthly, or $10 a month billed annually, which is a single $120 payment.
The App Store listing is messier. It shows ten in-app purchases for the same Unlimited plan: monthly at $19.99 and at $14.99, yearly at five prices from $19.99 to $119.99, a weekly option at $9.99 and a "50% Off Forever Monthly" at $7.49. Nothing says who is offered which. Read the price on your own screen before you confirm.
On the web, open your account settings and choose Manage Billing or Cancel. The terms say to do it at least 24 hours before the term ends to avoid the renewal charge. If you subscribed inside the iPhone app, Apple bills you, so cancel under Settings, your name, Subscriptions.
Do not count on money back. The terms call all fees non-refundable, with one exception: a technical fault Turbo AI cannot fix.
Yes, on the same terms, because it is the same product. TurboLearn renamed itself Turbo AI, turbolearn.ai redirects to turbo.ai, and the rebrand page lists pricing as unchanged.
Not one it advertises. No trial is listed on turbo.ai, in its FAQ or in the store listings. If checkout offers you one, the terms say you are charged when it ends unless you cancel first.
It is the same free plan for everyone, with no student plan on any official page. The terms set the minimum age at 16, with a parent's consent if you are 16 or 17.
Yes. It is a real product from TurboLearn, Inc. of Frisco, Texas, with 33K ratings on the App Store and over a million downloads on Google Play. Know the terms before paying: no refunds, individual arbitration, and getting permission to record a lecture is on you.
