Sottaku review
A broad, browser-friendly study app with strong review tools and a useful free tier.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Sottaku is a freemium language-learning app for learners studying up to 15 languages. It brings together grammar guides, sentence breakdowns, cloze quizzes, reading comprehension, dictionary lookup, audio, flashcards, and progress tracking. Placement quizzes help learners begin at an appropriate level, while community chat and language exchange add a social element. Access is available on the web, iOS, Android, and Chrome through a browser extension, with offline flashcard review for study away from a connection.
Its strongest fit is structured review. Flashcards use FSRS spaced repetition, and adaptive difficulty is paired with progress statistics to organize continued practice. The browser extension can look up words while reading online, and Sottaku-Yomitan supports that reading workflow. The Free plan includes grammar guides, quizzes, flashcards, and community chat, giving learners a substantial starting point without a paid subscription. Learners who want a guided mix of grammar, comprehension, vocabulary lookup, and review should find the feature coverage well aligned with that goal.
The paid plans focus on tracking, analysis, rewards, support, and browser-based saving. Sottaku Pro adds mistake tracking and analysis, advanced statistics, double quest rewards, priority support, and browser-extension lookup with flashcard saving. Sottaku Pro Annual provides an annual Sottaku Pro subscription. The US App Store shows a starting price of 14.99, while pricing may vary by region. Sottaku is a sensible choice for learners who prefer organized, reading-oriented study across devices. Those primarily seeking conversation or speech-focused practice should consider a product centered more directly on those activities.
