Common questions
- Is Koemoji free?
Yes. Koemoji is free to download and use, with no account needed. A paid plan with more AI transcription minutes is coming later. - What can I transcribe and translate?
Any Japanese podcast episode, plus videos and audio from your own iPhone: a recording from Photos, or an MP3, M4A, MP4 or MOV from Files. Nothing needs subtitles or an existing transcript, because Koemoji writes one itself and translates it. - What does the transcript show?
Each Japanese line with a reading over every word (romaji or hiragana), and a translation in your language underneath. The current line follows the audio as it plays, and a tap on any line plays from there. - Which languages are the translations in?
You choose one of 30 languages when you first open the app, including English, Chinese, Indonesian, Korean, Thai, Vietnamese, Spanish, French, Portuguese and German. You can change it any time in Settings. - Does it work for complete beginners?
Yes. The reading over every word means you can follow along before you can read kanji, and sentence mode lets you listen to one line at a time, repeat it, and slow it down to half speed. - Is there an Android version?
Not yet. Koemoji is for iPhone first (iOS 26 or later). Follow us on Instagram to hear when more platforms arrive.
An episode will not transcribe
- Check that the episode plays in the app first; a show whose feed is private or expired cannot be fetched.
- Files must be MP3, M4A, MP4 or MOV and under 1 GB.
- If you have used all 60 free minutes this month, Save tells you when they come back.
- Keep the app open or in the background; the transcript continues when you return.
