Hiroi: Live Meeting Translator

Every app can teach you a word. Only Hiroi can tell you when it came back. Hiroi listens to the conversations you're already in — the meeting, the call, the chat over lunch — and translates them live across Japanese, English, and Chinese. The phrases worth keeping become a study deck. Then the part nothing else does: when a phrase you studied turns up again in a real conversation, Hiroi quietly marks it gold. That's not a quiz score. That's proof the language is yours now. IT COMES BACK — AND YOU'LL KNOW Free translation understands the moment and forgets it. Hiroi remembers what you kept, listens for it, and tells you the day it returns. The words that keep coming back move to the front of your practice — because those are the words your life is actually made of. IT LEARNS YOUR VOICE, NOT A TEXTBOOK'S Every phrase you save is fed back into how Hiroi listens. The more you study, the better it hears YOUR vocabulary — your clients, your industry, your town. WORDS THAT SETTLE, AND STOP ASKING Once a word has come back to you in real life and you know it cold, Hiroi stops testing it. Your life is the review now. Your deck gets finished, not endless. CATCH IT LIVE Japanese, English, and Chinese in one live transcript — everything in your language. Face-to-face mode splits the screen for two people, two languages. KEEP WHAT MATTERED Save a phrase with a tap. Each card carries an AI explanation, a hand-drawn scene, and the moment it came from — so the word always remembers its context. STUDY YOUR OWN LIFE Saved phrases enter a spaced-repetition deck (FSRS), scheduled for the moment you're about to forget. You're not memorizing a stranger's textbook — you're studying your own meetings, your own town, your own life. PRIVATE BY DESIGN Audio is never recorded — it's understood as it streams and let go. Your transcripts, your phrases, and your deck are stored only on your device, never on our servers. START FREE Your first hour of live translation is free — no account needed. After that, two simple ways to keep going: hour packs that never expire, or 月帳, the monthly membership (3-day free trial) — 5 hours each month plus unlimited AI explanations, a natural shadowing voice with pitch scoring, weekly recap, and iCloud sync. Hiroi (拾い) — to pick up what's worth keeping. The words you barely caught today become the language you carry next time.
