You rated your confidence a 4 on that biology card. You felt good about it. Two weeks later, the exam asked the same question and your mind went blank.
That is the core problem with self-assessed spaced repetition. You think you know something because you recognise it. But recognition and recall are different cognitive processes, and one of them shows up on exams while the other just makes you feel prepared.
Brainscape built its entire algorithm around confidence ratings. Notesmakr is a study app and notes maker built around the Feynman Technique: collect material from any source, simplify it in your own words, then reinforce it with flashcards, quizzes, and mind maps powered by real spaced repetition.
This post compares both apps honestly. Brainscape wins in some areas. Notesmakr wins in others. By the end, you will know which one fits how you actually study.
What Is Brainscape?
Brainscape is a flashcard app that uses a proprietary algorithm called Confidence-Based Repetition (CBR). After viewing the answer side of a card, you rate your confidence from 1 to 5. Cards you rate low appear more frequently. Cards you rate high appear less often.
Brainscape runs on web, iOS, and Android with cross-platform sync. It offers a library of Certified Class decks, which are expert-curated flashcard sets for subjects like medical licensing (USMLE, MCAT), bar exam prep, AP exams, and languages.
The free tier limits you to 100 cards per class. Brainscape Pro costs approximately $9.99 per month billed annually ($119.88/year) and unlocks unlimited cards, full Certified Class access, offline study, and no ads.
What Is Notesmakr?
Notesmakr is a mobile study app designed around the Feynman Technique: take complex material and explain it simply until you truly understand it. You feed the app a PDF, audio recording, scanned document, or typed notes. The AI generates flashcards, quizzes, summaries, and mind maps from that material.
Where Brainscape asks you to rate confidence on pre-made cards, Notesmakr builds the entire study workflow. It uses the SM-2 spaced repetition algorithm to schedule your reviews at mathematically optimal intervals, not based on how confident you feel, but based on how your actual review history predicts forgetting.
Notesmakr also offers features Brainscape does not have: cloze cards with diminishing cues (progressive letter hints that adapt to your learning progress), AI quiz generation, mind map generation, and live multiplayer group study sessions.

Brainscape gives you curated content and a simple confidence loop. Notesmakr gives you AI-powered study material generation and multiple reinforcement modes. The right choice depends on whether you need pre-made decks or a tool that transforms your own material.
The Algorithm Question: CBR vs SM-2
This is the deepest difference between the two apps, and it matters more than most feature lists suggest.
How Brainscape's CBR works
After you flip a card and see the answer, you rate your confidence from 1 (no idea) to 5 (perfect). The algorithm shows low-confidence cards more often and high-confidence cards less often. It is simple, intuitive, and requires no configuration.
The problem: you are a terrible judge of your own knowledge. Psychologists call this the Dunning-Kruger effect at the micro level. Bjork and Bjork (2011) documented that students consistently overestimate how well they have learned material, especially right after studying it. When you rate a card 4 out of 5 because the answer "felt familiar," you may be confusing recognition with recall.
How Notesmakr's SM-2 works
SM-2 does not ask how you feel. It tracks your actual performance: did you get the card right or wrong? Based on your history, it calculates a specific interval for the next review. Get it right repeatedly, and the intervals grow (1 day, 3 days, 8 days, 21 days). Get it wrong, and the card resets to a shorter interval.
The SM-2 algorithm was created by Piotr Wozniak in 1987 and has been validated in decades of use. It is the foundation that both Anki and Notesmakr build on. The key advantage: the algorithm makes the scheduling decision, not your subjective confidence.
What the research says
Roediger and Butler (2011) demonstrated that retrieval practice (actively recalling information) produces significantly stronger long-term retention than recognition-based review. Rating your confidence after seeing an answer is recognition. Producing the answer from memory before checking is recall.
Kornell and Bjork (2008) found that students who felt most confident about their learning often performed worst on delayed tests. The feeling of knowing is unreliable as a study signal.
The core difference: Brainscape asks "How well do you think you know this?" Notesmakr's SM-2 asks "Did you actually know this?" One measures feeling. The other measures performance.
Where Brainscape Wins
Let's be honest about where Brainscape is the better choice.
1. Certified Class decks
If you are studying for the USMLE, bar exam, MCAT, or AP exams, Brainscape's Certified Class library gives you expert-curated flashcard sets ready to study. You do not need to create a single card. For students who want pre-built content from subject matter experts, this is a genuine advantage.
Notesmakr has no shared deck library. You create cards from your own material (manually or with AI). If you want to study someone else's deck, you would need to import it as an Anki .apkg file.
2. Web app access
Brainscape has a full web app. You can study from any computer without installing anything.
Notesmakr is mobile-only (iOS and Android). If you primarily study at a desktop computer, Brainscape gives you that option. Notesmakr does not.
3. Teacher and classroom tools
Brainscape offers a teacher dashboard where educators can create decks, share them with students via class codes, and monitor progress. For structured classroom environments, this is useful.
Notesmakr does not have dedicated teacher tools.
4. Simple onboarding
Brainscape's confidence rating system requires zero explanation. Rate 1 to 5, study, done. If you want the lowest possible learning curve with no configuration, Brainscape delivers that simplicity.
Where Notesmakr Wins
Now let's look at where Notesmakr pulls ahead.
1. Cloze deletion with diminishing cues
This is the biggest feature gap. Brainscape has no cloze deletion at all. You cannot create fill-in-the-blank cards.
Notesmakr offers cloze deletion with Diminishing Cue Retrieval Practice (DCRP). Based on research by Fiechter and Benjamin (2017), which found 44% better retention with progressive cues, Notesmakr reveals letters gradually based on your learning progress. First attempt: all blanked. After struggles: syllable-aware hints appear. As you master the card, hints disappear.
No other major flashcard app offers this adaptive cue system.
2. AI-powered study material generation
Brainscape added basic AI card generation, but its core workflow remains manual card creation or browsing pre-made decks.
Notesmakr takes a PDF, audio recording, scanned document, or typed notes and generates flashcards, quizzes, summaries, and mind maps from that material. One upload produces multiple study formats. This is especially powerful for students processing lecture notes or textbook chapters. You can turn a PDF into flashcards in seconds.
AI features require a Scholar+ plan. The free tier includes manual flashcard creation, cloze cards with DCRP, Anki import, and full SM-2 spaced repetition.
3. Multiple study modes beyond flashcards
Brainscape offers one study mode: the confidence-rating flashcard loop. That is it. No quizzes, no matching games, no mind maps.
Notesmakr gives you flashcards with SM-2, AI-generated quizzes (multiple choice with explanations), mind maps, note summaries, and live group study sessions. Different material benefits from different review formats. Vocabulary might work as flashcards. Conceptual relationships might click better as a mind map. Having options matters.
4. Algorithm-based scheduling vs self-assessment
As discussed above, SM-2 schedules based on your actual recall performance. CBR schedules based on your self-reported confidence. For serious long-term retention, algorithm-based scheduling is more reliable because it removes the subjectivity that makes self-assessment unreliable.
5. Anki deck import and export
Both apps can import Anki decks, but Notesmakr also exports in Anki-compatible format. If you ever want to move your cards to Anki, Notesmakr makes that easy. Brainscape only exports to CSV, which loses formatting and scheduling data.
6. Live group study
Notesmakr offers real-time multiplayer quiz sessions. A host creates a session, shares a join code, and participants compete on questions from their study material. Brainscape has no group study feature.
Import one of your existing study decks into both apps and study the same cards for a week. Notice which one surfaces the cards you actually struggle with. That difference is the algorithm at work.
Pricing Comparison
| Brainscape Free | Brainscape Pro | Notesmakr Free | Notesmakr Scholar+ | |
|---|---|---|---|---|
| Price | $0 | ~$9.99/mo (annual) | $0 | Varies by plan |
| Card limit | 100 per class | Unlimited | Unlimited manual cards | Unlimited |
| Spaced repetition | CBR (1-5 rating) | CBR (1-5 rating) | SM-2 algorithm | SM-2 algorithm |
| Cloze cards | No | No | Yes (with DCRP) | Yes (with DCRP) |
| AI generation | No | Basic | 5-note limit | Full AI pipeline |
| Pre-made decks | Limited access | Full Certified Classes | None | None |
| Offline study | No | Yes | Yes | Yes |
| Quiz mode | No | No | No | AI quiz generator |
| Anki import | Yes | Yes | Yes | Yes |
If you already have Anki .apkg decks, both apps can import them. But only Notesmakr preserves spaced repetition scheduling with SM-2 and adds cloze deletion with progressive hints on top.
Who Should Choose Brainscape?
Brainscape is the better fit if:
- You want pre-made, expert-curated flashcard decks and do not want to create your own cards
- You study primarily on a desktop computer and need a web app
- You are a teacher who needs to create decks for students and monitor their progress
- You want the simplest possible interface with no configuration
- You are preparing for a specific exam (USMLE, bar, MCAT) where Certified Classes cover your material
Who Should Choose Notesmakr?
Notesmakr is the better fit if:
- You want to generate study materials from your own notes, PDFs, or lectures using AI
- You value algorithm-based spaced repetition (SM-2) over self-assessed confidence ratings
- You use cloze deletion cards and want adaptive hints that respond to your learning
- You want multiple study formats (flashcards, quizzes, mind maps, summaries) from the same material
- You have existing Anki decks you want to import and study with a modern interface
- You study with friends and want live group quiz sessions
- You study primarily on your phone or tablet
Common Mistakes When Choosing a Flashcard App
Picking the app with more features instead of the right features. A pre-made deck library is worthless if your course uses custom material. AI generation is worthless if you already have perfect decks.
Ignoring the algorithm. The scheduling system determines whether you see cards at the right time. This matters more than the user interface or any single feature.
Overvaluing confidence ratings. Feeling confident after seeing an answer is not the same as being able to produce that answer on an exam. Test yourself with recall, not recognition.
Forgetting about portability. If you might switch apps later, check export options now. Being locked into one platform's proprietary format costs you flexibility.
Do not confuse "I recognised the answer" with "I can recall the answer." Brainscape's confidence ratings measure recognition. Your exams test recall. Choose a study method that practices what you will actually need to do.
Supercharge Your Study Sessions with Notesmakr
Notesmakr is an AI-powered notes maker that turns PDFs, lectures, and handwritten notes into flashcards, quizzes, and mind maps. If you are looking for a Brainscape alternative that prioritises active recall over passive confidence ratings, here is how to get started:
Upload a PDF, record audio, scan a document, or type your notes. You can also import existing Anki .apkg decks directly.
Let the AI create flashcards, quizzes, mind maps, and summaries from your material. One source, multiple study formats. AI features require a Scholar+ plan.
SM-2 schedules your reviews based on actual performance. Cards you struggle with appear more often. Cards you master stretch out to longer intervals. No self-assessment guessing required.
Create cloze deletion cards that blank out key terms. Diminishing cues reveal letters progressively as you learn, backed by research showing 44% better retention (Fiechter and Benjamin, 2017).

Frequently Asked Questions
Is Brainscape worth the price?
Brainscape Pro costs approximately $120 per year. It is worth it if you rely heavily on Certified Class decks for professional exams like the USMLE or bar exam. If you create your own cards, the free tier's 100-card limit is restrictive and the Pro price is steep compared to free alternatives like Anki or Notesmakr's free tier (which includes unlimited manual cards, cloze with DCRP, and SM-2).
Does Brainscape use real spaced repetition?
Brainscape uses Confidence-Based Repetition, which is a form of spaced repetition. However, it relies on your self-assessed confidence (1-5 rating) rather than algorithm-calculated intervals based on recall performance. Traditional SRS algorithms like SM-2 use your actual right/wrong history to schedule reviews, which removes the subjectivity of self-assessment.
Can I switch from Brainscape to Notesmakr?
Yes. Export your Brainscape decks as CSV files, then import them into Notesmakr. You can also import Anki .apkg files directly. Note that Brainscape's confidence history will not transfer since the two apps use different scheduling algorithms.
Is Brainscape better than Anki?
Brainscape is easier to use than Anki and offers pre-made Certified Class decks. Anki is free, fully customizable, has 10,000+ add-ons, and uses FSRS (a more advanced algorithm). For a detailed comparison between Anki and Notesmakr, see our Anki vs Notesmakr guide.
What is the best free Brainscape alternative?
For a free flashcard app with real spaced repetition, Notesmakr's free tier includes unlimited manual flashcard creation, cloze deletion with diminishing cues, Anki .apkg import, SM-2 scheduling, and handwriting notes. Anki is also free on desktop and Android. See our best free study app guide for a full comparison.
