Anki vs Mochi: pricing, features and which to choose

Anki was created by Australian developer Damien Elmes and first released in October 2006. Its name comes from the Japanese word for memorization. It became the standard flashcard tool for medical students, language learners and anyone who needs to retain large amounts of material, with communities sharing huge decks such as AnKing for the USMLE exams and Core 2k/6k for Japanese vocabulary. The desktop app is open source under the AGPL, written in Rust, Python and TypeScript, and maintained by Elmes's company Ankitects with community contributors. Sales of the paid iPhone app fund development, which keeps the desktop app, Android app and sync service free without ads.

You create notes with fields, and Anki generates cards from templates, so one note can produce forward, reverse and cloze-deletion cards. Each review asks you to recall the answer, then grade yourself Again, Hard, Good or Easy, and Anki schedules the next review accordingly. Cards can include images, audio, video and LaTeX or MathJax equations, and the app handles collections of more than 100,000 cards. Filtered decks, tags, a powerful search and detailed statistics help manage study. Collections are stored in an open SQLite format. Thousands of community add-ons extend Anki with features such as image occlusion, heatmaps, AI card generation and text-to-speech.

Anki's strengths are a proven scheduler with the modern FSRS option, zero cost on most platforms, complete control over cards and data, huge shared decks and a large add-on library. Its weaknesses are a dated, complex interface, a steep learning curve, manual card creation and a paid iPhone app. Quizlet is easier to use with study games and AI study tools, but locks more behind a subscription. RemNote and Mochi combine notes with spaced repetition. Knowt and StudyFetch generate flashcards from notes with AI. Memrise targets language learners. Choose Anki if you want the most configurable, free spaced repetition system and are willing to learn it.

Mochi is a flashcard app for people who want spaced repetition without clutter. It sits between Anki's depth and the simplicity of a notes app: cards are written in Markdown, notes and flashcards share one workspace, and the review screen stays minimal. Mochi says you can use it free forever with no sign-up, which appeals to learners who want to try a system before handing over an email address. It runs on Mac, Windows, Linux, iOS and Android, and Mochi describes itself as local first, storing data on your device and syncing when you are online. Language learners, students and professionals keeping technical knowledge fresh are the main audience, along with Anki users who want a cleaner editor.

Cards in Mochi are Markdown documents, so they can hold headings, lists, code, LaTeX, images and audio. Mochi also works as a note-taking app: you write notes in the same workspace as your flashcards and link them both ways with references, so a vocabulary card can point to a grammar note and the note shows its backlinks. Templates speed up card creation, so you can design a card type once, such as a vocabulary card with word, meaning and example sentence, and reuse it. Pro adds dynamic fields. Tags, filters and saved views organize large collections, and reviews are scheduled with SM-2 or FSRS using two answer buttons, according to NextLang. Pro users can also publish decks for others.

Mochi's strengths are a clean Markdown editor, a free tier with unlimited offline cards, apps on every major platform, templates for structured cards and a low Pro price. Its weaknesses are that sync needs Pro, the free AI and speech allowances are small, the community deck library is far smaller than Anki's and it has fewer add-ons. Anki is the free, open source standard with deep customization. RemNote combines notes and flashcards with an AI tutor. Quizlet offers quick shared study sets. Knowt turns notes into AI flashcards. Choose Mochi if you want linked Markdown notes and spaced repetition in one clean app.
