## What is KF transcription mixer?

KF transcription mixer turns the built-in microphone on iPhone/iPad into captions for meetings and talks. Choose a language and tap Start.

Adjust caption size from 100% to 200%, show reading guides, and tap originals to edit. Apple Translation displays translations after completed sentences while keeping earlier translations visible. Rotate 180 degrees for another person; supported translation language pairs can be swapped.

Share captions by QR/link in the app or browser. The app keeps captions on the main screen and shows connection status and participation controls only while sharing. Prepare and title a QR before an event and start it later from QR history. Viewers cannot edit the source and can change their own reading guides and text size.

Caption content is end-to-end encrypted on-device before Cloudflare relays it; decryption secrets and pre-existing saved histories are not sent. The browser viewer uses GitHub Pages. Providers can see connection metadata such as IP addresses. Sessions last at most eight hours; relay data is cleared on Stop, expiry or publisher interruption. Link holders can save copies that cannot be recalled. Reissue older QR codes and update both native apps. iPhone and iPad do not send or receive audio for calibration or comparison between devices. Wi-Fi or mobile data is used.

Save received captions from the session's beginning, including later corrections. Catch-up needs an active publisher; captions not received before an offline session ends cannot be recovered.

Edit saved titles/originals, update translations or delete histories. iCloud Drive sync for saved captions and dictionaries is on by default and can be turned off; use the same Apple Account. Local saving remains available. Supported devices can create saved-caption summaries on-device with Apple Intelligence. A compatible OS/language and enabled Apple Intelligence are required; check generated results.

Share saved captions as .fumicap files through AirDrop, Mail or other system share destinations. Files preserve titles, originals, translations, speakers, times and reading guides, without audio or the full dictionary. Preview received files and save independent histories without changing the source. These files are not encrypted by this app; share only with trusted recipients.

Apple network recognition is preferred by default and may send audio/vocabulary to Apple with permission. If unavailable, prepared on-device recognition is used. Explicit on-device mode never silently switches to external recognition. Download languages in advance; recognition and translation may be incorrect.

Supported built-in microphones offer Narrow/Wide pickup. Listen through supported speaker, Bluetooth or wired outputs, and continue active transcription in the background. There are no ads, tracking, analytics or app accounts. The interface supports 50 languages/regions.
