Most people do not switch study apps because the AI is bad. They switch because they were charged money they did not expect, or because the app summarised half a chapter without saying so. This guide covers nine apps for school and university: what each does well, which level it actually suits and where it lets you down.
First: what level are you studying at?
This is the question that matters most, and almost every comparison skips it. An app that is excellent for year 4 is no use in Sweden's Mathematics 3c course, while a tool built for university exam preparation is the wrong thing to give a twelve-year-old. Before comparing features, work out where you fit.
- Primary school, years 1–6 in Sweden. This is about homework help and the basics. Gamification is useful here: it can determine whether the app gets opened at all. Albert is built for exactly this age range.
- Lower-secondary school. The transition years. National exams in year 9, and the first time a student needs to study systematically rather than simply do homework.
- Upper-secondary school. Course grades against Skolverket's criteria, national exams, a final project and, for many, the Swedish Scholastic Aptitude Test. Subject depth now matters more than gamification, and most international apps do not understand Swedish syllabuses.
- University and college. Exams, reading lists in English and volumes of text that no flashcard app can deal with for you. The ability to work with long sources matters more than anything else here.
Why do people switch study apps?
Let us be honest: most of the apps below are real products with many satisfied users. The feature itself is rarely the problem. The problem is three things that no comparison table shows.
The subscription you could not cancel. The most common type of complaint across this category. If you subscribed through the App Store, your agreement is with Apple, not the app, so deleting your account in the app does not stop anything. Several Swedish cases have reached ARN, the National Board for Consumer Disputes, with exactly this story.
The free trial that charged you immediately. You enter your card for a free week and get charged straight away, or for a whole year instead of a month. The rule that protects you is simple and a little cynical: never enter a card for a trial you have not already decided to pay for.
The summary that only read half the source. You upload a forty-page chapter and get polished, confident notes back. They cover the first fourteen pages. Nothing tells you this, and you discover it when the exam asks about the rest. This is the most dangerous failure in the category, precisely because incomplete output looks just like complete output. It hits hardest at university, where sources are longest.
How to choose: a quick checklist
- Can you cancel with one tap inside the app? If cancellation requires an email, you have your answer. Test it before you pay.
- Will you be told before you are charged? An email seven days and one day beforehand costs the company almost nothing. Leaving it out is a choice.
- Does the app tell you what it actually read? “Processed 12 of 40 pages” is worth more than beautiful notes that silently stop at page twelve.
- Is the free tier useful, or just a demo with a card form?
- Does the app understand your level? The difference is clearest before national exams and university exams, where the syllabus or course reading is the whole point.
- What happens to your material if you leave? Export it before you cancel.

The apps, one by one
1. plue: best for understanding, not just summarising
Level: primary school, secondary school, university and college.
Best for: anyone who has read an explanation twice and still cannot see why it works that way.
What it does well. Almost every other app starts with an upload box. plue starts with your screen. You select the concept that stopped you while reading, whether in a lecture PDF, a course page in Canvas, a textbook or a past exam question, press a key, and get an explanation built around that specific point, right where you are. When your material is scattered across a learning platform, a textbook and handouts, this removes the step where most apps lose the thread.
The other difference is the output. Most apps summarise. plue draws. Circuits are laid out and solved, so the current in the answer is calculated rather than asserted. Physics diagrams are constructed. Figures in biology and cosmology come from real reference material. When a topic is visual, such as a force analysis, an orbit or a cell, a paragraph describing the picture is a worse answer than the picture itself.
The range of levels is deliberate. The same approach works for a year 5 fraction problem and a thermodynamics derivation, because what is missing in both cases is someone showing the steps rather than summarising the result.
- Reads your screen rather than relying on uploads
- Drawn figures for physics, chemistry, biology and maths
- Step-by-step explanations instead of a wall of text
- A free tier without a card and one-tap cancellation
Things to consider. plue is newer than the established names, and its library of sets created by other people is smaller. If you want a ready-made set for your exact chapter, Quizlet still wins on choice.
Price. A free tier with no card required. A paid plan with notice before renewal.
2. Albert: best for primary and lower-secondary school
Level: roughly years 1–9 in Sweden, with an emphasis on younger children.
What it does well. Albert is Swedish, built around the Swedish curriculum and carefully designed for ages 3–16. It focuses mainly on maths, with animated lessons and clear game elements. For a child in the later primary years, it is one of the few thoroughly developed Swedish options. The game mechanics are not a gimmick: they determine whether the app gets opened on a Tuesday evening. There are also related apps for Swedish, English, geography and programming.
- Swedish curriculum, content and spoken language
- Animated lessons rather than walls of text
- Game elements that give children a reason to return
- Several subjects in the same family
Things to consider. It does not cover upper-secondary courses. If you are taking Mathematics 3c, Albert is the wrong tool, however good it is for its intended age group. There are also recurring complaints about cancellations and charges, including cases at ARN. Cancel through the correct channel and save the confirmation.
Price. A subscription after the trial.
3. Eddler: best for upper-secondary maths and physics
Level: upper-secondary school.
What it does well. Eddler is not an AI app and should not be judged as one. It is a digital learning resource built course by course around the Swedish syllabus, with text, video and automatically marked exercises, largely written by qualified teachers. For Mathematics 3c or Physics 2, its content is more closely matched than a general AI tool can manage, simply because someone who knows the course wrote it.
- Organised by course around the Swedish upper-secondary syllabus
- Automatically marked exercises with complete solutions
- Built by teachers, not generated
- Works in the browser
Things to consider. Its coverage is narrow: maths, physics and programming. If you are struggling with history, social studies or English, Eddler will not help. There is no app, only the website.
Price. A personal subscription, or a school licence if your school already pays. Ask your teacher before paying yourself.
4. NotebookLM: best when the answer needs to be accurate
Level: upper-secondary school and university.
What it does well. Google's tool answers from the documents you upload and cites the passage the answer came from. That constraint is its main value: it invents much less than ordinary chat because it is not supposed to go beyond your sources. For upper-secondary projects, essays and undergraduate dissertations, it is the strongest app on this list. It handles many sources at once, which is exactly what a reading list involves.
Things to consider. It is a research tool, not a study tool. It does not track what you have forgotten or make a schedule. You have to bring the sources yourself.
Price. Free with a Google account.
5. Hypocampus: for medical students
Level: university medical degree programmes.
What it does well. Hypocampus is built specifically for Swedish medical students, with content written by doctors and former students. It covers the programme from preclinical biochemistry through to the medical proficiency test. Within its niche, it has no real competition in Sweden. Its sister product, HypocampusCare, is aimed at health and social care education.
Things to consider. If you are not studying medicine, the app is irrelevant. The cheaper tiers have had minimum contract periods, so read the terms before subscribing.
Price. A subscription, with student tiers.
6. Quizlet: the largest collection of ready-made sets
Level: all levels, although the sets are usually American.
What it does well. Nothing in this category comes close to Quizlet's collection. For vocabulary, concepts and fact-heavy courses, a good set often already exists, making it a waste of time to build your own.
Things to consider. It has the longest history of payment complaints in this category, and features that were free for years are now behind a paywall. Sets are rarely written around the Swedish curriculum.
Price. A limited free tier. Quizlet Plus costs around US$7.99 a month or approximately US$35.99 a year.
7. Knowt: best free option
Level: upper-secondary school and university.
What it does well. Knowt was built in response to Quizlet putting previously free features behind a paywall. Learning modes, practice tests and review are free, and it imports Quizlet sets directly.
Things to consider. The AI side is weak: users report explanations coming back empty. The paid plan is not cheap, at around US$12.49 a month when billed annually.
Price. A generous free tier, with a paid Ultra plan on top.
8. Brainscape: best for focused review
Level: upper-secondary school and university.
What it does well. You rate how confident you were in each answer, and reviews are scheduled accordingly. That is a more honest signal than right or wrong. If you already have good material and need a tool that makes you review at the right intervals, this is the most thoughtfully designed app on the list.
Things to consider. The AI features are limited. At around US$19.99, its monthly price is the highest here. The annual plan works out closer to US$7.99 a month.
Price. A limited free tier and a paid Pro plan.
9. StudyFetch: quick notes, with caveats
Level: mostly university.
What it does well. It moves quickly from an upload to finished study material and works well for course reading in English. Its Trustpilot score is around 3.9 out of 5, so this is not a bad product.
Things to consider. Around 22 per cent of its reviews give one star and concern almost exclusively unexpected charges and difficult cancellation. Its terms say fees are non-refundable except where required by law. As a consumer in Sweden, however, you have withdrawal rights under the Distance Contracts Act, which is worth knowing.
Price. The free tier offers roughly 10 chats, one study set and two uploads. Base costs around US$7.99 a month and Premium around US$11.99 a month.
Which should you choose for your level?
Primary school. Albert if your child needs the basics and a reason to open the app. plue when the question becomes “but why does it work that way?” In other words, when homework help is no longer enough and understanding is what is missing.
Lower-secondary school. plue for understanding before Sweden's year 9 national exams; Quizlet or Knowt for vocabulary and concepts. Albert still works in the earlier years, but students can outgrow it quickly.
Upper-secondary school. Eddler if the problem is Mathematics 1–5 or Physics 1–2. First check whether your school already has a licence. NotebookLM for the final project. plue for anything you are reading without understanding the underlying mechanism, which is the most common reason for getting stuck at a C.
University and college. NotebookLM for essays and long sources, Brainscape if remembering is the problem, and Hypocampus if you study medicine. plue when the course reading explains something in a way you cannot follow, which happens at university more often than people like to admit.
Cannot afford another subscription? Between them, NotebookLM and Knowt have enough free functionality for a whole academic year, at the cost of switching between two apps.
How to switch without being charged twice
- Cancel first, then switch. Take a screenshot of the confirmation.
- Check where the subscription is held. If you subscribed through the App Store, cancel through Apple. Deleting your account does not stop anything.
- Export before you lose access. Several apps cut off access immediately when you cancel, not when the paid period ends.
- Only bring what is current. This term's material, not three years of archives.
- Rebuild one whole course before deciding. Ideally the one you are most worried about.
- Test your hardest document. Check that the last page was included.
- Put the renewal date in your calendar. Even for an app that promises to warn you.
Frequently asked questions
Which study app is best for Sweden's national exams?
It depends on the subject and school year. For upper-secondary maths and physics, Eddler is built around the Swedish syllabus and is therefore more closely matched than a general AI tool. In year 9, the gap is more often in understanding than in material, so an app that explains things step by step is a better purchase than another deck of cards. One rule holds across all years: start with past papers, not the app. The tool should help with the things you already know you cannot do.
Which app works best at university?
At university, the problem changes: material is longer, often in English, and nobody has made a ready-made set for you. NotebookLM is strongest on long sources and is the only tool here that consistently refuses to answer beyond them, which matters when an invented reference can undermine an essay. Brainscape is best if remembering before an exam is the problem. If you study medicine, Hypocampus has virtually no competition in Sweden. And when the course reading explains something in a way you cannot follow, what is missing is understanding, not more notes.
Is there a genuinely free study app?
Yes. NotebookLM is free with a Google account and strongest if you want to trust the answer. Knowt has the most generous free flashcard tier. plue has a free tier that does not require a card, something worth checking carefully: a free trial that asks for card details in advance is different from a free tier, even if both use the word “free”. Expect the limit to concern how much material you can process each month rather than which features you can access.
How do I cancel a subscription that keeps charging me?
First, find out who holds the subscription. If you subscribed in an iPhone app, it is held by Apple and you cancel in your phone's subscription settings. Deleting the app or your account does nothing. If you subscribed on the web, cancel with the company. If charges continue after cancellation, you can dispute them as a consumer in Sweden: contact the company in writing first, then your bank if payments continue, and report the matter to ARN if the company does not put it right. Save screenshots of confirmations, because they are what decides a dispute.
Is using AI to study cheating?
The distinction is between a tool that does the work for you and one that makes the work understandable. Generating flashcards from your own textbook is not cheating. Getting a derivation explained step by step is not cheating and is probably one of the best uses of this technology. Submitting generated text as your own is cheating, as is photographing an exam question to get the answer. At university, the rules are also written down and the consequences are formal. Read your course guidelines and choose a tool whose output you would be comfortable showing.
What matters most
If you take away one thing, make it this: in this category, the product is rarely what lets you down. The subscription is. All the apps above make reasonable flashcards from a lecture, and the differences are smaller than the marketing suggests. The differences in whether you get charged eight months later for something you thought you had cancelled are enormous.
So choose on the boring details. Can you cancel with one tap? Does it warn you before charging? Does it tell you when it has only read half the document? And choose for your level. The most common reason a study app does not work is not that it is bad, but that it was built for someone five years younger or older than you.
