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) • Quick Notes on Apple Watch — tap the watch face and speak. Each passing thought shows up as text in the Notes tab on your iPhone, in the order you said them (Pro adds a title and category, and turns dates into calendar drafts) • 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, jotting down passing thoughts, 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. Apple Watch quick notes don't count toward this (up to 1 minute each). 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 is a one-time purchase — buy once, use forever. No subscription. A single one-time payment — there is no auto-renewal.
