Mojiokoshi: Voice to Text

On-device AI transcription. Your audio never leaves your iPhone. Mojiokoshi turns recordings and your own videos into text using on-device AI. All recognition happens right on your iPhone — your audio is never uploaded to the internet. That means it works on a plane, underground, or anywhere with no signal. ■ Highlights • Fully offline — audio and video never leave your device • Record and transcribe — speak and get text on the spot • Works with Apple Watch — tap the watch screen while recording to drop a marker; when your iPhone isn't with you, the watch can record on its own (up to 45 minutes per recording) • Transcribe from video — pull text from videos in your library • Transcribe an audio file — bring m4a / mp3 / wav from the Files app straight into text • Japanese, English, and Chinese, with automatic language detection • Chinese shown in Simplified or Traditional script • Translate transcripts into many languages — on-device, offline once language packs are installed • AI Advisor "Intent Phrasing" — turn what you mean into natural, situation-aware wording (on-device AI, Pro) • AI Summary & Minutes — organize transcripts into an overview, key points, decisions, and to-dos; export as PDF / Markdown / Word (on-device AI, Pro) • Polish — add punctuation and line breaks to a transcript so it reads cleanly. The words themselves are never changed (on-device AI, Pro) • Export text (.txt) and subtitles (.srt) (Pro) • Automatic paragraphs at natural pauses — long recordings don't come back as one solid block • Search, organize, copy, and share your history • Choose your model — from lightweight to high-accuracy Large v3 • Light/Dark support with 7 American-retro themes ■ Great for Meeting minutes, interview transcripts, lecture and field notes, organizing voice memos, creating subtitles for videos, and finding the right way to say something to people abroad. ■ Privacy first No analytics, no ad SDKs. Transcripts are stored only on your device. We do not collect your data. ■ Pricing Free: up to 1 minute per transcription, 5 per day. Mojiokoshi Pro removes the time and count limits and unlocks text / subtitle (SRT) export, AI Summary & Minutes (PDF/Word export), Polish, and the AI Advisor. • Mojiokoshi Pro (one-time purchase) — US$29.99 Buy once, use forever.
