Kotonote: On-Device Transcribe

Your voice, yours alone.

Kotonote keeps recording, transcription, summarization, and search entirely on your device. Your voice, your transcripts, and your summaries never leave your iPhone.

—— One tap to record ——
Meetings, interviews, lectures, voice memos — capture them in high quality with a single tap. Background recording and automatic resume after interruptions (such as incoming calls) keep long sessions safe.

—— Stop recording, the rest is automatic ——
Hit stop and Kotonote chains transcription → speaker separation → summary on its own. Just wait, and a first draft of your minutes is ready.

—— Readable, speaker by speaker ——
On-device AI transcribes automatically and color-codes every speaker (A / B / C…). Rename them later or reassign turns whenever you like.

—— Summaries that fit the job ——
Minutes (decisions, to-dos, discussion points), key-point bullets, interview Q&A, lecture notes. The AI even writes the title. Switch templates to regenerate or edit.

—— Synced playback ——
Tap anywhere in the transcript to jump to that moment in the audio. Text highlights in sync with playback. Change speed or loop a section.

—— Search by meaning ——
Even when the words don't match, semantic search surfaces the closest passages across every recording. Full-text (keyword) and semantic search work together — tap a hit to jump straight to the audio.

—— Export freely ——
Audio (m4a / wav), text (txt / md), subtitles (srt / vtt), summaries (md / txt), and JSON. Send anything through the standard share sheet.

—— About privacy ——
Your audio, transcripts, and summaries are processed entirely on-device and are never sent to a server. There is no cloud sync, so back up manually and keep your own copies (data is lost if the device is lost or erased).
Note: a network connection is used only for the initial model download and for serving ads.

—— Every feature, free ——
No paywalled features. Ads keep the app free.

Requires iPhone 15 Pro or later / iOS 26 or later. Transcription and interface available in Japanese and English.
