It's week three. You've uploaded the first two lectures to a study app, the flashcards look decent, and then week three's slides won't go in without an upgrade. That's the moment most people end up comparing Knowt and StudyFetch, so I'll answer it the way that matters: how far does each free plan carry you?
Knowt's free plan can get you through a whole unit, as long as flashcards and practice tests are how you like to study. The study modes are free and the limits sit on the AI extras. StudyFetch's free plan is closer to a trial. Reviews describe it as roughly 10 chats with its AI tutor, one study set and two uploads, which runs out before week two. StudyFetch is built around chatting with an AI about your material, and that's the part it charges for.
I build The Study Mill, which competes with both, so weigh my take accordingly. I've tried to be specific about where each one is better than what I make.
What each free plan gives you
At the time of writing, third-party reviews and pricing trackers mostly agree on this:
| Knowt (free) | StudyFetch (free) | |
|---|---|---|
| Flashcards | Unlimited sets, make your own or generate from notes | About 1 study set |
| Study modes | Learn, matching, practice tests, spaced repetition | Quizzes and cards from that one set |
| AI from your files | Yes, with a monthly cap | About 2 uploads |
| AI tutor chat | Kai, capped on free | Spark.E, about 10 chats |
| Lecture recordings | Notes from videos | Paid plans only |
| Imports Quizlet sets | Yes | Not advertised |
Neither app publishes its free limits as clearly as I'd like, and StudyFetch's pricing page is hard to read without signing up. Treat the numbers as approximate and check inside the app.
Knowt: a deck app with a generous free tier
Knowt started as the free answer to Quizlet's paywall, and that still shows. Learn mode, practice tests, matching and spaced repetition all work without paying, and it pulls in your old Quizlet sets so you don't start from zero. If your unit is heavy on terms (pharmacology drug classes, anatomy, legal definitions), you can study a full semester on the free plan. I covered the Quizlet side of this in Quizlet vs Knowt.
Where it costs money is the AI. Generating cards from PDFs is capped each month on free, and unlimited chat with Kai, its AI tutor, is on Ultra. Reviewers put Ultra at around US$12.49 a month billed yearly, and roughly double that if you pay monthly. That's more than most students expect from "the free one".
Where Knowt is better than StudyFetch: a free plan you can live on, a big shared library, and a familiar flashcard workflow.
StudyFetch: an AI tutor first, cards second
StudyFetch is built the other way round. You upload course material and the centre of the app is Spark.E, an AI tutor that answers questions about it. Flashcards and quizzes come out of the same upload. On paid plans it also handles lecture audio and video, and the top tier adds a live lecture assistant.
The trouble is that the free plan only lets you sample that. About 10 chats and one study set covers one lecture, maybe two. Reviews put the Base plan at around US$7.99 a month, with a higher tier that lifts the caps. Annual pricing is reported inconsistently across reviews, so I won't quote a number.
Where StudyFetch is better than Knowt: if you learn by asking "but why?" over and over, a tutor that has read your slides is more useful than a deck. On paid plans it also works from lecture audio and video.
The question underneath the question
Comparing free plans hides a bigger difference. Knowt helps you remember things. StudyFetch helps you understand things by talking about them. Most units need both, and most exams lean on the second one more than students expect.
There's a trap with chat-first tools, though. Asking an AI questions feels like studying, but you're the one asking, not the one answering. Memory gets built when you have to pull an answer out of your own head, which is why testing yourself beats rereading in study after study. The research on that is some of the most reliable in learning science. A tutor is brilliant when you're stuck. It isn't a substitute for being quizzed.
So the honest framing is:
- Mostly definitions and terms? Knowt's free plan, no question.
- Mostly "explain" and "apply to this case"? You need something that makes you write answers, not just read the AI's.
Where The Study Mill fits
This is the one I build. You upload a week (slides, PDF, Word, notes, a photo of handwritten notes, or a lecture recording) and it becomes short lessons with analogies, flashcards, a quiz that mixes multiple choice with written answers marked by AI, notes, a tutor you can ask, and Walk & Learn, where Milli and Luke teach the week as audio and ask you questions you answer out loud. Daily review brings back the questions you missed.
The free plan is 2 classes, with as many weeks in each as you need. It doesn't include everything: Pro (A$7.99 a month or A$49 a year, half price with a .edu or .edu.au email) adds unlimited classes, exam mode and cram sheets. For one or two units, though, the free plan is meant to last the semester, not a week.
Where Knowt beats it: a shared library and Quizlet import. The Study Mill only studies what you upload. Where StudyFetch beats it: the live lecture assistant during class, if that's how you work.
Side by side
| Knowt | StudyFetch | The Study Mill | |
|---|---|---|---|
| Free plan lasts | A unit, if you're card-based | About a lecture | 2 classes, all weeks |
| Built around | Flashcards | AI tutor chat | Your week's lecture |
| Marks written answers | No | Partly | Yes |
| Audio lessons with questions | Not a focus | Not a focus | Walk & Learn |
| Shared library | Large | No | No |
| Paid from | Around US$12.49/mo yearly | Around US$7.99/mo | A$7.99/mo, A$3.99 for students |
If StudyFetch's caps are what sent you here, I went through more options in StudyFetch alternatives. If it's Knowt's AI limits, try Knowt alternatives.
Try both on the same lecture
The fairest test is one lecture, three apps, the same evening. Upload it to each, study for twenty minutes, and see which one you open again the next day. If you want The Study Mill in that test, it takes about a minute and no card.
