Read full description

Slavonaut is reading-first Slavic language learning: real texts from day one, a tap-anything dictionary that understands grammar, and spaced-repetition review that makes words stick. SIX SLAVIC LANGUAGES TO EXPLORE Russian, Polish, Czech, and Croatian ship full courses — 63 lessons each, from the alphabet to B1+ cases, aspect, and conversation. Serbian and Bulgarian start with focused 12-lesson starter paths. Honest labels in the language picker show exactly how much content each language has today. READ FROM DAY ONE — FREE Over 200 short readings written for learners, graded from absolute beginner (A0) to B1, with listening audio. Every reading is free. Tap any word — even a conjugated or declined form — and Slavonaut resolves it to its base form and shows what it means and why it looks the way it does. Tap between words to reveal the sentence translation. A DICTIONARY THAT UNDERSTANDS GRAMMAR Search in English or any Slavic language. Entries include pronunciation, word forms, conjugation tables, and etymology. If a rare word isn't covered yet, a clearly labeled AI-generated entry fills the gap so you're never stuck mid-sentence. REVIEW THAT RESPECTS YOUR TIME Save words while you read; Slavonaut schedules each one with spaced repetition, right before you'd forget it. An optional daily word notification and per-language streaks keep the habit going — no guilt trips. COURSES THAT GET TO THE POINT Learn Cyrillic in your first sitting, then build through greetings, cases, verb aspect, and real conversation. Practice questions are generated from the actual words in your lessons, and Cyrillic answers accept Latin transliteration while you're still learning the script. NO ACCOUNT NEEDED Start as a guest — everything is saved on your device. Create a free account later to back up your words and sync across devices. SLAVONAUT PLUS Reading, the dictionary, review, and the first two chapters of every full course are free. Slavonaut Plus unlocks the full depth of every path and learning multiple languages. Slavonaut Plus is available as an optional auto-renewable subscription. Payment will be charged to your Apple Account at confirmation of purchase. Your subscription automatically renews unless cancelled at least 24 hours before the end of the current billing period. Manage or cancel anytime in Settings.
