How to Dictate iMessages on Mac with Hearsy

The Messages app on Mac already supports Apple's built-in dictation, so why use Hearsy? Speed and accuracy. Apple's dictation has a noticeable startup delay, sends audio to Apple's servers by default, and produces raw unformatted text. Hearsy's Parakeet engine transcribes in about 200 milliseconds with no network round-trip, and optional AI enhancement turns casual speech into properly punctuated, clean messages.

Step-by-step setup

1. 1

   Open Messages on your Mac

   Launch the Messages app from your Dock, Spotlight, or Applications folder. Open an existing conversation or start a new one.

2. 2

   Click the message input field

   Place your cursor in the text field at the bottom of the conversation. This is where Hearsy will paste your dictated text.

3. 3

   Press your Hearsy hotkey

   Trigger recording with your keyboard shortcut (default: Fn twice or a custom hotkey). The menu bar indicator confirms Hearsy is actively listening.

4. 4

   Speak your message

   Talk naturally. Say exactly what you want to send, whether it's a quick 'on my way' or a longer explanation. Hearsy handles punctuation and formatting for you.

5. 5

   Press the hotkey again to finish

   Tap the hotkey once more. Hearsy transcribes your speech on-device, applies AI enhancement if enabled, and pastes the text into the Messages field. Hit Enter to send.

Why use Hearsy for iMessage?

Apple's dictation works, but it has real limitations on Mac. There's a delay before it starts listening, transcription accuracy drops with background noise or accented speech, and the output is unformatted text that you often need to edit before sending. It also sends audio to Apple's servers unless you specifically enable on-device mode, which limits language support.

Hearsy is built differently. Everything runs locally on your Mac from the start. The Parakeet engine processes speech in under 200 milliseconds, so there's no waiting for a server response. You get your text immediately after you stop speaking.

The biggest advantage for messaging is AI enhancement. When you dictate a quick text, you often speak in fragments or half-sentences. AI enhancement turns that into a clean, natural-sounding message without changing your intent. Your iMessages read like you typed them carefully, even when you rattled them off in five seconds while making coffee.

Tips for better results

• ✓

  Use Hearsy instead of Apple dictation when you need speed. Hearsy's 200ms transcription has no startup delay, while Apple's dictation takes a moment to connect before it begins listening.

• ✓

  Enable AI enhancement for longer messages. It turns spoken rambling into well-structured text that reads naturally, which matters more in personal messages than you'd expect.

• ✓

  Dictate replies while doing other things on your Mac. Click into the Messages conversation, hit the hotkey, speak, and you're done without switching mental context.

• ✓

  For group chats that move fast, dictation helps you keep up. Speaking a reply is three times faster than typing one, so you can stay in the conversation without falling behind.

• ✓

  Switch to the Whisper engine if you're texting in a language Parakeet doesn't support. Whisper covers 99+ languages at the cost of slightly slower (1-2 second) transcription.

• ✓

  Dictate into the search field to find old conversations. Place your cursor in Messages' search bar and dictate a contact name or keyword.
