Studyh vs Anki: which is better for studying?
Short answer
Anki is the most powerful, free, and flexible spaced-repetition tool out there — perfect if you love full control and don't mind building your own decks. Studyh wins when what you really want is to save time: its AI turns your PDFs, text, and audio into flashcards, quizzes, summaries, and mind maps, with active recall, spaced repetition, and the Feynman method already built in, plus a Portuguese and ENEM focus. In short: Anki for control and being free; Studyh for speed, a ready-made method, and zero setup.

What is Anki?
Anki is a spaced-repetition flashcard program first released in 2006 that has become a gold standard among medical students, language learners, and anyone who needs to memorize a lot for the long term. It is open-source and free on desktop (Windows, macOS, and Linux), on Android (via AnkiDroid), and on the web through AnkiWeb, which also syncs your decks across devices. The only paid version is AnkiMobile, the official iPhone and iPad app, which is a one-time purchase that helps sustain the project.
Anki's strength is its algorithm. For years it used SM-2, derived from SuperMemo research, and today it also offers FSRS, a more modern algorithm that tunes your review intervals more precisely to your actual performance. Add a huge ecosystem of add-ons, fully customizable card templates, and community-shared decks, and you get a tool with almost endless possibilities.
That power comes at a cost: Anki was never designed to be pretty or beginner-friendly. The interface is utilitarian and dated, the initial setup can be intimidating, and syncing between phone and computer sometimes takes patience. Most importantly, Anki does not create content for you. Every flashcard has to be written by hand or imported from a shared deck — there is no built-in AI that reads your PDF and generates the material automatically.
What is Studyh?
Studyh is an AI study platform built on the cognitive science of learning. The core idea is simple: instead of spending hours assembling material, you let the AI do it from your own content. You upload a PDF, paste text, or add an audio file (which is transcribed automatically), and Studyh generates ready-to-study flashcards, quizzes, summaries, mind maps, and Feynman-style exercises.
Underneath that automation are the techniques research shows to be most effective: active recall (actively retrieving information instead of rereading), spaced repetition (reviewing at the right intervals to lock things into long-term memory), and the Feynman method (explaining in your own words to expose gaps in understanding). The method is baked in, so you don't need to know how to configure anything to study the right way.
Studyh is Portuguese-first and oriented toward the ENEM and other Brazilian admissions and civil-service exams, though it works for any subject. It runs as a web app, has a free plan to get started, and paid plans priced in Brazilian reais up to around R$69.90. The trade-off is the opposite of Anki's: you give up some granular control in exchange for speed, convenience, and a method that's already in place.
Where they overlap
Despite their different philosophies, Studyh and Anki share the same scientific foundation. Both believe real learning requires retrieval effort: you have to try to remember, get things wrong, correct them, and review at increasing intervals. Both use active recall and spaced repetition as their main engines, and both were designed to fight the illusion of competence that passive rereading creates.
They also both work for any subject, from language vocabulary to anatomy, math to history. And in both, daily consistency beats marathons: a few minutes of review every day outperforms hours crammed the night before an exam.
The differences that matter
The number-one difference is who creates the content. In Anki, it's you — always. That guarantees cards perfectly tailored to what you want to learn, but it costs time and discipline. In Studyh, the AI generates the material from your sources in seconds, which is a game-changer when you have a lot of content and little time.
The second difference is control versus convenience. Anki offers absolute control over the algorithm, card types, and behavior via add-ons. Studyh hides that complexity and makes the good decisions for you, prioritizing a frictionless experience. The third is language and context: Studyh was born in Portuguese and targets the ENEM and Brazilian exams, whereas Anki is neutral and expects you to adapt everything yourself.
Pros and cons
Anki
Pros: free and open-source on most platforms; powerful spaced-repetition algorithm (SM-2 and FSRS); highly customizable with add-ons; works offline; a massive community with ready-made decks.
Cons: steep learning curve; dated, utilitarian interface; you must create cards manually; no built-in AI to generate material from your content; setup and syncing can be fiddly; the iPhone/iPad version is paid.
Studyh
Pros: the AI generates flashcards, quizzes, summaries, and mind maps from your PDFs, text, and audio; zero setup; the method (active recall, spaced repetition, and Feynman) is built in; Portuguese-first with an ENEM and exam focus; a free plan to get started.
Cons: less fine-grained control over the algorithm than Anki; needs a connection since it's a web app; no giant add-on ecosystem; advanced plans are paid.
Who each one is best for
Choose Anki if you're a committed self-learner, you like tuning every detail, you want something completely free and offline, and you don't mind investing time building or importing decks. It's the classic choice for medical and language students who think in terms of years of use.
Choose Studyh if you want to turn your own material into effective study without spending hours making cards, you prefer a tool that's simple and polished, you study in Portuguese and aim for the ENEM or Brazilian exams, and you value having the study method ready out of the box. It's ideal for beginners or for anyone with a lot of content to cover in a short time.
And it doesn't have to be one or the other: many students use Studyh to generate and practice quickly, and Anki for very long-term memorization. The two complement each other well.
The verdict
There's no absolute winner — there's the right tool for your moment. If you want raw power, a free price tag, and total control, Anki is hard to beat. If you want to turn your PDFs and notes into study material instantly, with a built-in method and a Portuguese focus, Studyh was made for you. The best way to decide is to try it.
Frequently asked questions
Is Studyh better than Anki?
It depends on your goal. Anki is more powerful, free, and works offline, making it unbeatable if you want total control over spaced repetition. Studyh is better if you want to save time: the AI generates flashcards, quizzes, and summaries from your own PDFs, text, and audio, with a study method built in and a focus on Portuguese and the Brazilian ENEM exam.
Is Anki really free?
Mostly, yes. Anki is free and open-source on desktop (Windows, macOS, Linux), on Android (AnkiDroid), and on the web through AnkiWeb. The one exception is iPhone and iPad: the AnkiMobile app is a paid, one-time purchase that helps fund the project.
Does Studyh have spaced repetition like Anki?
Yes. Studyh uses spaced repetition and active recall as the core of its method, alongside the Feynman technique. The difference is that Anki gives you granular control over the algorithm (SM-2 and FSRS) and add-ons, while Studyh automates those decisions so you can focus on studying instead of configuring.
Can I turn my PDFs and notes into flashcards automatically?
In Studyh, yes: upload a PDF, paste text, or add audio, and the AI generates flashcards, quizzes, summaries, mind maps, and Feynman-style exercises. In Anki you have to create cards manually or import shared decks, because it has no built-in AI that generates material from your own content.
Which one is best for exams and test prep?
Studyh shines when your source material maps directly to an exam, especially in Portuguese for the ENEM and Brazilian admissions tests, since the generated content comes out in the right language and context. Anki works very well for exams too, but you have to build or find the decks yourself, which takes more upfront effort.
Is it worth using both together?
For many people, yes. You can use Studyh to quickly turn your sources into study material and practice with a ready-made method, and Anki for highly customized long-term memorization. They complement each other: speed and automation on one side, control and depth on the other.
