Ready to take your fluency to the next level? SonLerni is for intermediate speakers (A2–B2) who have made some progress in learning a language but lose native speakers at full speed. Level up with native podcasts in English, French, German, Spanish and Hebrew, with synced transcripts, paced playback and phrase-by-phrase replay. TOTAL IMMERSION, NOT TEXTBOOK AUDIO Real conversations at natural speed, full of the slang, idioms and shortcuts textbooks skip. Podcasts let you eavesdrop on natives. SonLerni makes sure you catch what they say. AI TUTOR Lost? Tap the phrase. The AI tutor translates it literally, what the speaker actually means and the nuance: casual, regional or formal. Ask a follow-up, then another. The AI tutor loves rabbit holes. TOO FAST? SLOW IT DOWN • A transcript that follows the audio phrase by phrase • Replay by phrase, not by seconds • Fine-tune the playback speed FLASHCARDS BUILD THEMSELVES Every phrase you ask about becomes a flashcard, with the sentence you heard it in. A few minutes of review a day keeps it. PICK YOUR LEVEL Made for A2–B2. Set your level and get episodes that stretch you without losing you. FIVE LANGUAGES. ONE APP. English, French, German, Spanish and Hebrew. Switch languages any time. SEE YOUR PROGRESS Minutes listened, active days, flashcards and weekly goals, all on one screen.
