Where Anki is the better choice
Anki has been the reference spaced repetition tool for almost two decades, and for good reason:
- It works for anything. Medicine, law, kanji, music theory — Anki doesn’t care what is on the card.
- It is endlessly customizable. Card templates, fields, filtered decks and a large add-on ecosystem let you shape every detail.
- It runs everywhere, including Android and desktop, and its deck format is open and portable.
- Huge shared deck library. For popular languages you can often start from a community deck instead of an empty one.
If you enjoy building your own system, or you are learning a language Zenzu doesn’t teach yet, Anki is hard to beat.
Where Zenzu is the better choice
Most learners who drop Anki don’t drop it because of the algorithm — they drop it because making good cards is slow. Zenzu removes that step:
- Cards come from content you chose. Paste a YouTube link, open a podcast episode or snap a photo of a page, then tap a word or select a phrase.
- Context is kept automatically. Each card carries the sentence it came from, and phrases get cloze deletion without manual formatting.
- Pronunciation is built in. Native text-to-speech plays for every word and sentence.
- You learn from your own language. Explanations and the AI coach work in English, Ukrainian, German, French, Spanish and Portuguese — not only through English.
Can you use both?
Yes. Many learners keep Anki for non-language subjects or long-standing decks and use Zenzu for new vocabulary mined from what they watch and read. Because both use FSRS, review intervals feel similar across the two.
