The only pairing on this site where neither tool is Google's and neither is ours, which makes it the closest thing here to a straight fight.
Studley AI generates study sets from your uploads and grades written answers for completeness.
Turbo AI records live lectures and turns them into notes, flashcards and a podcast.
They overlap on generated practice and diverge completely on where the material comes from.
Round by round
Five jobs, and which of the two does each one better.
Round 1
Knowing the price before you pay
Studley AI
Studley publishes $14.99 a month or $97.99 a year on its own site, and its App Store listing agrees. Turbo is $19.99 a month or $119.88 a year, but you will not find that anywhere on turbo.ai: it has no pricing page, and the three tiers named in its terms carry no prices, so the figures only appear at the paywall inside the app. Turbo is also the more expensive of the two by about $5 a month.
Round 2
Capturing a live lecture
Turbo AI
Uncontested. Turbo records the room, filters the conversation around you, and produces structured notes with chapters. Studley does not record anything at all: it works from material you already have. If your problem is that you cannot listen and take notes at the same time, this round ends the comparison.
Round 3
Grading what you wrote
Studley AI
Studley’s written test takes an open-ended answer and grades how complete it was rather than marking it right or wrong, and its paper grader assesses an essay against a rubric you supply. Turbo’s quizzes include short answer and fill-in-the-blank, which is more than most, but nothing in it assesses a paragraph of prose the way Studley does.
Round 4
Reliability of what comes out
Studley AI
Both have a specific failure mode and Studley’s is milder. Studley’s is incomplete notes, cut off mid-chapter, which is its main Trustpilot theme. Turbo’s is losing the recording entirely: reviewers describe a two-hour lecture failing to save, another capturing 25 minutes of two hours, and recording stopping if you leave the app. A truncated summary is recoverable from your source. A lost lecture is not.
Round 5
The free tier
Neither
Studley’s free plan is one study set, ever, and a failed generation still consumes it. Turbo’s free tier has unpublished caps tight enough to run out within days. Neither functions as a free plan; both are trials that do not say so. If a genuinely free tool is what you need, neither of these is it, and NotebookLM is.

Who should pick which
These diverge on where your material comes from, so the choice is usually settled before you compare a single feature.
Pick Studley AI if
- You already have the slides and readings
- You want written answers graded, or an essay assessed against a rubric
- You want to know what a tool costs before you reach a paywall
- You would rather have a truncated summary than a lost recording
Pick Turbo AI if
- You need live lectures captured and nothing else will do
- Most of your studying happens on a phone in short gaps
- You want a podcast of the lecture for the commute
- Your bottleneck is getting from audio to readable notes
A third option, and it is ours
Both of these generate material and then stop. Studley scores a written answer and tags the question; Turbo tracks a flashcard Memory Score. Neither works out why you got something wrong, and neither remembers it next week.
That is what Akono does instead, and it is ours, so weigh this accordingly. It builds a course from your material and runs sessions where a tutor asks the questions, reads what you wrote, and picks the next question from your answer. What you misunderstand stays on file until you can state it correctly, and the plan works backwards from your exam date.
Where it is honestly the wrong tool: it does not record lectures, so it does not replace Turbo's core feature. It has no photo solver and no essay grader, so it does not replace Studley's. It is built for exams weeks out rather than tonight. And there is no free tier: a 3-day trial, card required, then €11.99 a month or €59.88 a year.
