If you can read Japanese but can't follow it spoken at native speed, your ear is the bottleneck. Dictation trains exactly that: hear a real sentence, type it, see every character you missed.

Flashcards prove you know words. Dictation proves you can hear them — at full speed, in real sentences, from speakers who aren't slowing down for you. If you already grind Anki decks, this is the same discipline pointed at your ears.
37,736 real sentences read by native Japanese speakers — not synthesized voices. All speeds, many voices.
Type in kana and kanji with your IME, exactly as you heard it. No word bank, no hints.
Every miss is shown character by character. An English gloss appears when you get it wrong.
Spaced repetition brings hard sentences back right before you'd forget them.
You will fail most sentences at first — native-speed Japanese is unforgiving, and that is precisely why practicing it works. No streaks, no gems, no mascot. Just real audio, a text box, and an algorithm that remembers what you miss.
