The best app to memorize in 2026? Our #1 is LalaLearn — yes, it's ours, and it's also the only one in this comparison that turns your syllabus into songs so you memorize by listening: of the seven, no other uses music as a method. But the honest answer depends on how you study, so here's the full comparison with Anki, Quizlet, Knowt, RemNote, NotebookLM and StudyFetch — strengths and weak spots of each, ours included.
How do you choose a memorization app?
Three questions are enough. First: how do you retain best — reading and self-testing (flashcards), or listening (audio, music)? Second: how much of the app is actually free for your case? Almost all are freemium, but what each one caps varies a lot. Third: is it in your language and built for your kind of exam? With that in mind, here's the real picture of 2026.

LalaLearn: our #1 — the only one in this comparison that turns your syllabus into songs
Full transparency: LalaLearn is ours. We rank it first for an objective, verifiable fact: none of the others uses music as a study method — the closest are NotebookLM's conversational podcast and Knowt's voice tutor. LalaLearn turns your notes into songs (musical memory is among the most durable: you remember songs from twenty years ago, not what you re-read yesterday), with a VERBATIM mode that keeps legal or medical text exact, and a community where you listen for free to songs others already created on your subject, build playlists per course — and can even earn money when others play yours. Available in Spanish and English, with songs in several languages — plus a focus on Spanish civil-service exams and university that the US apps don't have.
When should you NOT pick it? If visual self-testing with pure flashcards is your thing, Anki or Knowt will serve you better. LalaLearn shines if you retain best by listening, if your syllabus is dense and literal (laws, definitions), or if you want to review in dead time — on the way to class, at the gym — without opening the book.
Anki: the queen of flashcards (if you put in the hours)
Anki is pure spaced repetition: you rate how well you remember each card and it schedules the next review right before you'd forget it. It's free and open source on desktop and Android (the official iPhone app is paid, and it funds the project), and its add-on ecosystem is unmatched. In exchange, everything is manual: building good decks takes time, the learning curve is real, and there's no AI doing the work for you. It only does flashcards — no summaries, no audio beyond reading cards aloud.
Quizlet: the endless library (with a toll)
Quizlet shines for its huge library of ready-made decks by teachers and students worldwide, and its study modes (flashcards, learn, test, games). The catch: many of the powerful modes — Learn, Test, study guides — live in the paid plans, and even Plus has monthly usage limits. Audio is limited to reading your cards aloud.
Knowt: the free alternative to Quizlet
Knowt openly positions itself as the free substitute for Quizlet, and delivers: the core study modes (flashcards, learn, practice tests, spaced repetition) are unlimited without paying; what the free plan caps monthly is the AI features (notes from recorded lectures, PDF and YouTube summaries). Its tutor Kai can quiz you out loud or make you a podcast of the topic. Downsides: the website can't be switched to other languages — only the mobile app can — and its world revolves around the American school system.
RemNote: notes and review in the same place
RemNote integrates flashcards inside your own notes: you write, and AI generates cards and quizzes from them (and from PDFs), with spaced repetition on top. For anyone who wants a single tool to take notes and review — medicine and computer science are its star cases — it's a neat idea. The free plan is solid on basics but caps annotated PDFs and AI credits, and there's no audio format at all.
NotebookLM (Google): your syllabus as a podcast
NotebookLM — which Google is renaming Gemini Notebook — is different: you upload YOUR sources (PDFs, web pages, videos) and the AI answers only from them, citing where everything comes from. Its star feature is Audio Overviews: two AI voices discussing your material, podcast-style, available in Spanish and downloadable. It's free with a Google account (paid plans raise the daily limits). Two caveats Google itself acknowledges: the audio can introduce inaccuracies and isn't a complete view of your material. And it's spoken conversation — not music: no melody or rhyme anchoring the memory.
StudyFetch: the all-in-one AI tutor
StudyFetch aims to be the Swiss army knife: upload your materials and it generates a study plan, notes, flashcards, practice exams and an AI tutor (Spark.E) you can talk to by voice. Downsides: pricing details aren't public (you only see them after signing up) and the free plan limits key features like lecture recordings.
Which one should you pick?
Our #1 is LalaLearn: if you memorize best with music, your syllabus is dense, or you want to review without staring at a screen, nothing else on this list does the same — and trying it is free. Now, being honest about each case: total control and manual work, Anki; ready-made decks for almost anything, Quizlet (or Knowt for the same without paying); notes and review together, RemNote; interrogating your PDFs and hearing them as a podcast, NotebookLM; a generalist AI tutor, StudyFetch.
