Utter: AI Dictation for Mac & iPhone

Introduction to Utter: AI Dictation for Mac & iPhone

Utter is a system‑wide voice‑to‑text application for macOS and iOS that converts speech into well‑structured, ready‑to‑use text. Instead of producing raw transcripts, Utter applies AI prompts to clean, format, or reshape content before inserting it directly at the cursor in any app.

The app supports custom prompts and multiple AI modes to generate emails, notes, summaries, code prompts, and more. A searchable voice history with audio replay and cross‑device sync enables users to review and reuse past recordings and transcripts. Utter supports 50+ languages and translation. It is available for Mac (macOS 14.4+) and iPhone (iOS 17.0+).

How Utter: AI Dictation for Mac & iPhone Works

On Mac, Utter starts with a global hotkey to begin and end dictation from any application with a text field. On iPhone, a custom keyboard enables dictation within any app. Speech is transcribed and the resulting text is inserted directly where the cursor is positioned, minimizing context switching.

After capture, AI post‑processing removes filler words, corrects casing, and formats elements such as numbers, times, dates, email addresses, and phone numbers. Users can select from built‑in AI modes (e.g., email, notes, document, professional message, code prompt) or create custom prompts tailored to their workflow. Utter supports 50+ languages and can translate transcripts as needed.

Each session is saved to Voice History with audio replay for context and accuracy checks. Transcripts are searchable, and content stays in sync across Mac and iPhone. For privacy and control, Utter supports BYOK and uses zero data retention during audio processing (audio is processed and discarded).
