1. Noji

Noji is a flashcard app for creating flashcards and learning them with spaced repetition. It is designed to be easy to start with: pick a study preset such as “Study languages” or “Study medical material”, and Noji schedules your reviews. A General mode lets you review all cards in a row when you need to cram.

Cards are quick to make. You can type them, generate them with AI from documents, notes, and images, hide parts of a picture with image occlusion, or import decks from Anki, Quizlet, and spreadsheets. There are 50K+ pre-made decks in the library, you can share decks and edit them with friends, and the app works offline and syncs across web, iOS, and Android.

Pricing: Noji provides a free version with all the essential features. Upgrading to the premium version unlocks additional benefits, including adding pictures and rich editing to your cards, unlimited daily learning, custom spaced repetition presets, and pronunciation mastery through auto-created audio.

Best for: students and language learners who want spaced repetition without a long setup.

2. Anki

Anki is a free, open-source flashcard program and the reference point for spaced repetition. You can switch between the FSRS and SM-2 algorithms, design your own card templates, and extend the desktop app with community add-ons. It has a large collection of free shared decks and works fully offline.

Anki asks more of you in return: the interface is utilitarian and the settings take time to learn. No built-in AI card generator is documented.

Pricing: free on Windows, macOS, Linux, AnkiWeb, and Android (AnkiDroid). AnkiMobile for iOS is a $24.99 one-time purchase on the US App Store.

Best for: power users who want to control every detail. See Noji vs Anki.

3. Quizlet

Quizlet is the best-known study app, with more than 900 million user-created study sets according to Quizlet. Beyond flashcards it offers Learn, Test, and Match modes, classroom games, and AI study tools. In August 2026 it added a Spaced Repetition study method to Flashcards.

On a free account, Learn and Test are limited: Quizlet’s help center says non-subscribers get a limited number of Learn rounds and one practice test per set. Hiding ads and studying offline are listed as subscription benefits.

Best for: finding a ready-made set for almost any class. See Noji vs Quizlet or our list of Quizlet alternatives.

4. Knowt

Knowt combines flashcards, notes, and exam prep. Its free plan is generous with study modes: Learn, Practice Test, Spaced Repetition, and Match are all included for your own sets. AI summarizers turn PDFs, videos, and slides into notes and flashcards, with 1 AI summary per month on the free plan.

Pricing: free plan available. Ultra, which removes ads and limits on the AI tools, starts at $7.99 per month billed annually at the time of writing, or $24.99 billed monthly.

Best for: students who want Quizlet-style modes without paying.

5. Brainscape

Brainscape asks you to rate each card from 1 to 5 and shows lower-rated cards more often, a method it calls Confidence-Based Repetition. It stands out for expert-made Certified classes covering exams and professional certifications.

Pricing: free to create unlimited flashcards and study 2,500 pre-loaded ones. Pro, needed for images and sounds on cards and for export, costs $19.99 per month or $7.99 per month billed annually ($95.88).

6. RemNote

RemNote is a note-taking tool with spaced repetition built in: flashcards are created from your notes as you write. It supports SM-2 and FSRS and imports Anki decks with their schedules. Desktop and mobile apps work offline.

Pricing: free with unlimited notes and flashcards and some limits (for example 5 image occlusion images and 250 AI credits per month). Pro costs $10 per month, or $8 per month billed yearly.

Best for: long-term learners who want notes and flashcards connected.

7. Mochi

Mochi is a Markdown-based notes and flashcards app. It is free forever without sign-up, with unlimited cards and offline use, and it imports and exports Anki decks, Markdown, and CSV. FSRS is available as an alternative to its own algorithm.

Pricing: syncing across devices needs Pro, at $5 per month billed annually or $6 billed monthly.

Best for: people who think in Markdown and like local-first tools.

8. Gizmo

Gizmo builds flashcards and quizzes from PDFs, YouTube videos, notes, and slides with its Magic Import. It uses game mechanics such as hearts and streaks, and spaced repetition runs automatically with nothing to configure.

Pricing: the free plan includes 15 Hearts in Memorise mode and 2 Magic Imports per day. Gizmo Unlimited removes the limits; Gizmo says its price depends on your device and region.

Best for: turning your material into quiz practice fast.

How to choose a flashcard app

• If you want to remember things for months, choose an app with spaced repetition and a free plan you can use every day.
• If you already have cards somewhere else, check the import options first so you don’t have to retype them.
• If you study on your phone, make sure the app works offline and syncs with the web.
• If you want ready-made material, look at the size and quality of the shared deck library.
