FAQ
Everything about Studyh.
Active recall, spaced repetition, the Feynman method, pricing and more. Short, direct answers.
What is Studyh?
Studyh is a study platform that helps you learn more actively instead of just rereading your material. It combines active recall, spaced repetition using a scheduling heuristic inspired by SM-2, an AI-guided Feynman technique, an ENEM-style question generator, flashcards, mind maps, and review scheduling. The idea is simple: you follow a cycle of learn, review, and prove what you know, which may support access to the material over time. Studyh was built with Brazilian exam students in mind, with native Brazilian Portuguese as its main focus, while the English version is currently in beta.
How does active recall work?
Active recall means closing your material and trying to remember the content from memory, instead of just rereading or highlighting. That effort of pulling information out of your head, even when you get it wrong, can be more useful for learning than passive review. In Studyh you practice this regularly: you answer questions, explain concepts, and test yourself before checking the answer. It is the same mental muscle you use on the actual exam, so training it from the start can help you prepare more directly than just feeling like you know the material.
What is spaced repetition and SM-2-style scheduling?
Spaced repetition means reviewing content at increasing intervals instead of all at once. Recall can fade after learning; reviewing after a delay can help keep information accessible for longer. Studyh uses a scheduling heuristic inspired by SM-2: review intervals are adjusted based on reported performance, with items that are easier to recall generally returning after longer gaps and difficult items returning sooner. It is a product heuristic, not a prediction of an individual's exact forgetting.
What is the Feynman technique and how does Studyh use it?
The Feynman technique means explaining a topic in simple words, as if teaching it to a beginner. If you get stuck or fall back on vague terms, you may have found a gap in your understanding. In Studyh, Feynman practice uses AI to guide that explanation: you teach the concept, and the AI can point out where it was unclear or incomplete. This turns rote memorization into a more active comprehension exercise. The AI-guided Feynman technique is part of the Studyh subscription, available on the Monthly and Annual plans.
Does Studyh work for exams and competitive tests?
Yes. Studyh was designed for Brazilian exams, so it includes an ENEM-style question generator and native Portuguese context, but the method can also be applied to any large body of content that requires long-term retention. That covers university entrance exams, the ENEM, and public-service competitive exams. You use active recall and spaced repetition to reinforce the material, practice with questions, and review at an appropriate interval. It can support both people starting from scratch and those doing final-stretch revision, because the learn, review, and prove cycle can be adapted to different types of content.
How is artificial intelligence used in Studyh?
AI can make studying more active and personalized. It runs the Feynman technique: you explain a concept and the AI points out gaps, mistakes, and confusing parts, helping you correct them. The AI also generates ENEM-style questions and flashcards from your content, and supports building mind maps. Instead of just handing you ready-made answers, it prompts you to think and recall the information yourself. The AI features require an internet connection, since the processing happens online.
Is Studyh better than Anki?
It depends on what you want. Anki is a very powerful, free, and generic spaced repetition system (SRS), but it requires you to build everything manually and has no exam context. Studyh adds the AI-guided Feynman technique, an ENEM-context question generator, and a native Brazilian Portuguese experience on top of spaced repetition. If you just want configurable flashcards and already know Anki well, it does the job. If you want a more guided flow, with AI correcting your understanding and questions in the real exam style, Studyh tends to save you time.
Studyh vs Quizlet: what is the difference?
Quizlet focuses on flashcards and memorization games, which can be useful for reviewing terms and definitions. Studyh takes a broader active-study approach: it encourages active recall and uses AI to provide feedback on your understanding through the Feynman technique, not just to flip a card. It also offers spaced repetition with a heuristic inspired by SM-2, an ENEM-style question generator, and mind maps, all in native Portuguese. If you only want quick flashcards, Quizlet may be enough; if you want a more guided learning flow with feedback, Studyh may be a better fit.
Studyh vs RemNote: which should I choose?
RemNote is strong as a note-taking and personal knowledge management (PKM) tool, blending notes and flashcards in one place. It is designed for building a connected knowledge base. Studyh has a different focus: it is an active-study platform for exams, with an AI-guided Feynman technique, ENEM-style questions, a review heuristic inspired by SM-2, and native Portuguese. If your goal is organizing lots of interlinked notes, RemNote may suit that workflow. If your goal is practicing recall and receiving AI-assisted feedback for entrance or competitive exams, Studyh may be a more direct fit.
How much does Studyh cost and what are the plans?
Studyh is subscription-only, with no free plan: you need to subscribe to use the platform. In US dollars, the plans are Monthly at US$6.99 and Annual at US$59.99 (in Brazilian Reais, there is also a Quarterly plan at R$20.99). You can pay by credit card, which sets up a recurring subscription that renews automatically, or, for Brazilian Reais plans, via PIX, a one-time payment with no automatic renewal that unlocks access for the length of the plan, with an email reminder near the end of the period if you want to reactivate. No plan has a lock-in contract, so you can cancel whenever you want, with no penalty. The annual plan usually works out cheaper per month than paying monthly.
Does Studyh have a free plan?
No. Studyh does not have a free plan or a free trial: you need to subscribe to one of the paid plans (Monthly or Annual, plus a Quarterly option in Brazilian Reais) to use the platform. You can subscribe with a credit card, which sets up a recurring charge that renews automatically, or, for Brazilian Reais plans, pay via PIX, a one-time payment with no automatic renewal that unlocks access for the length of the plan, with an email reminder near the end of the period if you want to reactivate. Either way, there is no lock-in contract, so you can cancel whenever you want.
Do I need a credit card to use Studyh?
Not necessarily. Besides a credit card, which sets up a recurring subscription, Studyh also accepts PIX for plans priced in Brazilian Reais: a one-time payment with no card and no automatic renewal, where you pay once and access unlocks for the length of the plan you chose. Near the end of that period, you get an email reminder to reactivate if you want to keep going. Whichever payment method you choose, there is no lock-in contract.
Can I cancel anytime?
Yes. Studyh's paid plans have no lock-in or minimum commitment, so you can cancel at any time. There is no cancellation fee. If you subscribed to a monthly or annual plan and decide to stop, you just turn off the renewal. The idea is that you stay with Studyh because the method is helping you, not because you are stuck in a contract. If you have any questions about canceling, you can reach the team by email at contact@studyh.tech or on Instagram at @studyh.tech.
How does Studyh generate questions and flashcards?
Studyh uses AI to turn PDF, TXT, Markdown, pasted text, or a typed topic into ENEM-style questions and active-recall flashcards. From the material you want to study, the AI creates questions that ask you to retrieve information from memory rather than just recognize it. The flashcards can then enter your spaced repetition routine with a heuristic inspired by SM-2, returning at intervals adjusted to reported performance. The ENEM-style question generator is one of the features included in a Studyh subscription. The AI features require an internet connection to work.
Does Studyh create mind maps?
Yes. Mind maps are part of Studyh's features and help you visually organize the connections between the concepts in a topic. They are useful for getting an overview of the material and seeing how ideas link together, which complements active study with questions and flashcards. Along with active recall, spaced repetition, and the Feynman technique, mind maps are part of the learn, review, and prove cycle. This way you do not just memorize isolated pieces, but can also build a clearer picture of the content as a whole, which may make recall easier later.
How does review scheduling work?
Studyh's review scheduling organizes what you need to review and when, based on spaced repetition and a heuristic inspired by SM-2. Instead of guessing when to revisit each piece of content, the platform calculates a suggested interval from reported performance: items you recall easily generally come back after longer gaps, and the ones you miss return sooner. This can concentrate attention on material that may need more reinforcement. The schedule is based on performance; it does not claim to bring an item back at the exact moment before forgetting.
Can I use Studyh on my phone?
Yes. Studyh is a web app you open in your phone, tablet, or computer browser, with no app store needed. There is currently no native iOS or Android app, and AI-powered processing requires an internet connection. In practice, you just open the site in your browser and study from wherever you are when connected.
How long until I see results with Studyh?
There is no exact timeframe, because it depends on your routine, your starting point, your material, and your consistency. Active recall and spaced repetition may support learning when practiced regularly, but the perception of progress varies with those factors. A practical approach is to keep the learn, review, and prove cycle regular rather than studying a lot at once and then stopping.
How many hours a day should I study?
There is no magic number, and more hours does not always mean more learning. Consistency matters more than intensity: two hours a day that you actually complete beat six hours planned and abandoned in the first week. The best approach is to be honest about your real free time, after work, classes, and rest, and split it into short, focused blocks, reserving part for active practice and questions. Studyh helps you make better use of that time by concentrating your reviews on what you most need to reinforce, instead of everything at once.
Is Studyh useful for self-taught learners and people out of school?
Yes. Studyh's method can be useful for anyone who needs to learn and retain content, not just students in school. Self-taught learners, people returning to study after years, professionals changing careers, and exam candidates can all use active recall, spaced repetition, and the AI-guided Feynman technique. Since you decide what you want to study, the platform can adapt to your goal. The learn, review, and prove cycle is broadly applicable: it can be adapted for a 17-year-old preparing for entrance exams as well as for an adult studying entirely on their own.
Is Studyh available in English?
Yes, Studyh has an English version, but it is currently in beta. The platform's main focus is the Brazilian audience, with native Brazilian Portuguese and exam context like the ENEM. The English version exists to reach students in other countries and is gradually maturing over time. If you study in Portuguese, you will get the most complete experience, tuned to your context. If you prefer English, you can use the beta version knowing that some features may keep evolving. Questions or feedback can go to contact@studyh.tech.
What does the learn, review, and prove cycle mean?
It is the core flow of Studyh. First you learn the content, through reading, lessons, or by explaining it with the AI-guided Feynman technique. Then you review at increasing intervals, using spaced repetition with a heuristic inspired by SM-2 to organize the next attempts. Finally, you practice what you know by solving ENEM-style questions and testing yourself with flashcards, which is where active recall happens. Repeating this cycle may support retention over time rather than relying only on rereading or highlighting.
What is the difference between the Monthly and Annual plans?
Studyh has no free plan: every plan unlocks full access to the platform, including the complete Feynman technique and the ENEM-style question generator. The difference is the billing cycle and price: Monthly at US$6.99 and Annual at US$59.99, which usually works out cheaper per month (a Quarterly option at R$20.99 is also available in Brazilian Reais). You can pay by credit card, which renews automatically, or, for Reais plans, via PIX, a one-time payment with no automatic renewal that unlocks access for the length of the plan. No plan has a lock-in contract, so you can cancel whenever you want.
Does Studyh's method have a scientific basis?
Studyh is informed by established learning research. Active recall and spaced practice have substantial evidence in particular study designs, because they require the effort of remembering rather than only passive reading. Spacing research and systems such as SM-2 help explain ways to organize review, but do not guarantee one result or interval for every learner. The Feynman technique, explaining things in simple words, can reveal gaps in understanding. Studyh brings these ideas together into a practical learn, review, and prove flow, rather than relying only on rereading and highlighting.
