Best Flashcard Apps of 2026 Compared

The best flashcard app in 2026 depends on who makes the cards and what you already have: Scholarly if you want AI cards built from your own PDFs, recordings, and videos; Anki if you will type your own cards and want free, best-in-class scheduling; Knowt if you want the old free Quizlet experience with your sets imported; Brainscape if you are studying for a certification and want an expert-built deck; RemNote if your cards should live inside your notes; and Quizlet if you just need the biggest library of pre-made sets.

Every app below was re-checked against its own website on October 20, 2026. Third-party pricing changes often, so we link each vendor's pricing page instead of quoting its prices.

What changed in 2026

• Anki's latest release is 26.09.3. FSRS has been built into Anki since version 23.10 (AnkiMobile 23.10, AnkiWeb, and AnkiDroid 2.17 and later), as an alternative to the legacy SM-2 scheduler. Desktop, Android, and AnkiWeb remain free; AnkiMobile on iOS is a paid purchase.
• Quizlet's help center describes Learn as a Quizlet Plus feature; non-subscribers can start a free Learn session to try it. Students added to a teacher-created class get free Learn and Test on that class's sets.
• Knowt advertises unlimited free Learn mode and two-click Quizlet imports, while its plans page now lists the AI summarizers, AI podcast generator, and voice tutor under the paid Ultra plan.
• Brainscape's free Basic plan includes AI-generated flashcards, imports, spaced repetition, and a set of pre-loaded flashcards; Pro adds the premium catalog.
• RemNote sells three tiers: Free, Pro, and Pro with AI.
• Scholarly tiers sources per creation by plan (Free 1, Premium 10, Laureate 20) and runs models from eight AI labs, including open-source options. Flashcard creation, SM-2 review, and Anki .apkg or PDF export (paid plans) remain in place.

Why flashcards work: the science in brief

Two well-documented effects from cognitive psychology explain why flashcards outperform re-reading:

1. The testing effect (retrieval practice). Actively pulling an answer from memory strengthens it far more than passively reviewing it. Roediger and Karpicke's retrieval-practice studies are the classic reference: students who tested themselves retained more over a week than students who re-studied the same material.
2. The spacing effect. Memory decays on a curve (Ebbinghaus's forgetting curve). Reviewing a card just before you would forget it flattens that curve, which is why spaced-repetition algorithms such as SM-2 (the SuperMemo lineage) and the newer FSRS schedule each card individually instead of showing you everything every day.

Any app on this list gives you retrieval practice. The differences are in who makes the cards (you, an AI, or a stranger's public set), how the schedule works, and what it costs.

Scholarly: best for AI-generated cards from your own material

Scholarly is a source-grounded workspace for students and professionals: you upload the material you actually need to learn (PDFs, Word files, slides, images, audio recordings, YouTube videos, websites, or pasted notes) and it generates editable flashcards from it, alongside quizzes, practice exams, AI podcasts, narrated video lectures, slides, and an AI chat that answers from your sources.

Free plan: free signup with no credit card. One lifetime file upload (up to 8 MB; PDFs are processed up to the first 32 pages) and one lifetime AI creation, which can be a flashcard deck or any other output. Free study mode covers the first 10 cards of a deck, with 5 study answers in total; unlimited study is on paid plans. Sharing a deck by link is free.

Best for: licensure and certification candidates working from their own study guides, professionals turning work documents into review material, and anyone who records lectures or meetings and wants cards made from that material instead of typed by hand. Start with the flashcard maker or PDF to Flashcards.

Limits: the free allowances never reset. Exporting a deck to Anki (.apkg) or PDF requires a paid plan. Sources per creation are capped by plan: 1 on Free, 10 on Premium, 20 on Laureate. There is no large public set library; Scholarly assumes you bring your own material.

Other features:

• Per-card spaced repetition using SM-2 scheduling
• Import from Quizlet, Anki (.apkg), Google Docs, Notion, Word, PowerPoint, Markdown, and CSV
• The same source can also become a quiz, a practice exam, a podcast, or a video lecture

Pricing (October 2026): Premium is $30/month or $144/year in US dollars (regional prices apply in many countries) with 15 AI creations per week and files up to 300 MB. Laureate is $99/month with 80 AI creations per week and larger file and page limits. See pricing.

Anki: best fully free power tool

Anki has been the serious memorizer's tool for two decades. It is open source, and its scheduler offers FSRS alongside the legacy SM-2 algorithm.

Free plan: everything on Windows, macOS, Linux, Android (AnkiDroid), and the free AnkiWeb sync service. See Anki's site.

Best for: medical students, language learners, and anyone willing to invest setup time for maximum long-term control. The shared-deck ecosystem is enormous.

Limits: a steep learning curve and a utilitarian interface, no built-in AI generation, and the official iOS app (AnkiMobile) is a paid purchase. If you want to study in Anki without making cards by hand, you can generate cards in Scholarly and export the deck as .apkg on a paid plan. For that trade-off, see Scholarly vs. Anki.

Quizlet: biggest library, narrow free tier

Quizlet is still the household name with the largest library of pre-made study sets.

Free plan: creating sets and flipping through cards. Quizlet's help center says Learn is available to Quizlet Plus subscribers, and non-subscribers can start a free session to see what it is like. Students in a teacher-created class get free Learn and Test on that class's sets.

Best for: quickly grabbing a pre-made set for a common course, or classes where the teacher distributes Quizlet sets.

Limits: the Learn mode that made Quizlet famous is effectively paid for individual studying, and studying a stranger's public set means studying what their class covered. Check Quizlet's upgrade page for current plans. For a deeper comparison, see Scholarly vs. Quizlet.

Knowt: best free Quizlet-style alternative

Knowt grew by being what free Quizlet used to be, and by making migration easy.

Free plan: unlimited note and flashcard creation, unlimited Learn mode, practice tests and games, Quizlet imports "with 2 clicks," and live collaboration. See Knowt's plans page.

Best for: anyone who wants the old free-Quizlet experience with their existing sets carried over.

Limits: Knowt's plans page lists the AI summarizers for PDFs, videos, images, and PowerPoints, the lecture recording summarizer, the AI podcast generator, and the voice tutor under the paid Ultra plan, which is also ad-free.

Brainscape: best for certified, pre-made decks

Brainscape's distinctive feature is confidence-based repetition: after every card you rate your confidence 1 to 5, and that rating drives the repeat schedule.

Free plan: Brainscape's Basic plan is "free forever" for typing, importing, sharing, and studying your own flashcards, using AI to make flashcards, spaced repetition, progress tracking, and a set of pre-loaded flashcards. See Brainscape's pricing.

Best for: professionals studying for a certification where a vetted, expert-built deck beats making your own.

Limits: the premium catalog and power features sit behind Pro, and it is a flashcard app, so the same source cannot also become a quiz, a summary, or a narrated lecture without leaving the tool.

RemNote: best notes-plus-flashcards hybrid

RemNote treats flashcards as a property of your notes: write a line, mark it as a card, and it enters your review queue.

Free plan: unlimited notes and flashcards on unlimited synced devices, plus small allowances of annotated PDFs, image occlusion cards, and AI credits. See RemNote's pricing.

Best for: heavy note-takers who want their notes and their review queue to be the same document.

Limits: a real learning curve, and the AI tutor and most power features sit on the paid Pro and Pro with AI tiers.

How do you choose? A 30-second decision guide

• You have the PDFs, slides, or recordings and you are short on time: Scholarly (PDF to Flashcards turns a document into an editable deck).
• You want zero cost forever and maximum control, and you will type your own cards: Anki.
• You have years of Quizlet sets and just want free study modes back: Knowt, or bring the sets into Scholarly through the Quizlet importer or the Text to Flashcards tool.
• You are studying for a professional certification: Brainscape's certified decks.
• Your notes are your life and cards should live inside them: RemNote.
• You just need one pre-made set for tomorrow's quiz: Quizlet's library is still the biggest.

Tips for effective flashcards (whatever app you pick)

1. One concept per card. Cards that ask two things teach neither.
2. Test understanding, not trivia. "Why does X cause Y?" beats "What was the sample size in study Z?"
3. Write (or edit) cards in your own words. Even AI-generated cards are worth a quick edit pass; rephrasing is itself encoding.
4. Review daily, briefly. Ten minutes a day beats a two-hour weekly cram; spaced repetition only works if you show up for the spacing.
5. Don't skip hard cards. The cards you keep failing are exactly where the learning happens.
6. Add images where they help. Diagrams and charts give your memory a second hook.

FAQ

What is the best free flashcard app in 2026?

Anki is the most powerful fully free option (outside iOS, where AnkiMobile is a paid purchase). Knowt's free tier is the closest match to old free Quizlet, with unlimited Learn mode. If you want AI-generated cards from your own materials, Scholarly's free account includes one lifetime AI creation and one upload to try it, and a study mode that covers the first 10 cards of a deck with 5 study answers in total.

Is Quizlet still free in 2026?

A free Quizlet account still exists, but Quizlet's help center describes Learn as a Quizlet Plus feature, with a free session for non-subscribers to try it. Students in a teacher-created class get free Learn and Test on class sets.

Can AI really make good flashcards from a PDF?

Yes, with a caveat: quality depends on the AI being grounded in your actual document rather than guessing from a topic name. Scholarly generates cards directly from the uploaded source and keeps them editable, so you can fix or delete weak cards before studying. Treat any AI deck as a draft you review once; that pass doubles as a first study session.

Can I move my decks between these apps?

Mostly. Scholarly imports Quizlet and Anki decks (plus Google Docs, Notion, Word, PowerPoint, Markdown, and CSV) and exports Anki .apkg or PDF on paid plans. Knowt imports Quizlet sets directly. Anki imports .apkg and text files. Brainscape imports existing flashcards on its free tier.

Should I switch apps mid-semester?

Only if your current app is actively blocking you (paywalled study mode, no mobile access, cards you cannot edit). Migration is cheap, but the consistency of daily review matters more than the tool.

Conclusion

The flashcard market has clear lanes in 2026: Anki for free power, Quizlet for library size, Knowt for the free Quizlet-style experience, Brainscape for certifications, RemNote for note-takers, and Scholarly for people who want cards built from their own material, with SM-2 spaced repetition and the rest of a study workspace (quizzes, practice exams, podcasts, video lectures) attached.

If your study materials are PDFs, recordings, or videos, start there: create a free Scholarly account, upload one document, and see what a deck grounded in your actual material looks like. No credit card required.
