Speak it.
It's written.
Hold one key, anywhere on your Mac, and just talk. Blurt turns voice into text the way it should be — strips the ums, sets the punctuation, and lays clean, finished words exactly where your cursor sits. No window. No account. No friction.
By the numbers
One key. Three beats.
Then it's just words.
If you can hold a key, you already know how to use Blurt — push-to-talk dictation with a built-in AI editor, powered by OpenAI under your own key.
Small app. Remarkably articulate.
It cleans up, it doesn't just transcribe
Removes filler words, fixes punctuation, breaks paragraphs, and obeys spoken commands like “new line” or “make that a list.”
Works in every app you already use
Mail, Slack, your code editor, Notes, the browser address bar — if it has a text field, Blurt types into it.
Speaks your language
Auto-detects what you speak — English, Russian, German and dozens more — and formats it correctly. No language to pre-pick.
A waveform that knows its place
A tiny, click-through pill floats at the bottom of the screen. It never steals focus, never gets in the way.
Your key, your call
Push-to-talk on Right Option by default — remap it to Left Option, a Command key, Control, or Fn.
See exactly what it heard
Every dictation shows the raw transcript beside the cleaned-up result. Type a messy sentence below and watch the clean-up run live — then copy the result.
Your voice never lingers — and it stays yours.
Blurt runs entirely on your Mac with your own OpenAI API key, stored in the macOS Keychain. Your audio is sent only to OpenAI to become text — Blurt keeps nothing. No servers, no account, no telemetry, no audio stored.
Questions, answered.
Is Blurt free?
Yes. The Blurt app is completely free with no subscription. You bring your own OpenAI API key and pay OpenAI directly for what you use — typically a few cents a day — with no markup and no middleman.
How is Blurt different from Apple's built-in Mac dictation?
Apple Dictation transcribes raw speech and times out. Blurt produces finished text: it removes filler words like um and uh, fixes punctuation, breaks paragraphs, and obeys spoken commands like "new line" and "make that a list". There's no timeout — you hold the key for as long as you like.
Does Blurt work in any app on my Mac?
Yes. Blurt is system-wide, not browser-only. If an app has a text field — Mail, Slack, Notes, VS Code, Word, your browser's address bar — Blurt types clean text right where your cursor sits.
Why do I need my own OpenAI API key?
Blurt has no servers. Bringing your own key means your audio goes directly from your Mac to OpenAI under your account, you pay OpenAI's low per-use rate instead of a subscription, and Blurt never sees your key, audio, or text. Your key is stored only in the macOS Keychain.
Is Blurt private? Where does my audio go?
Blurt has no account, no servers, no telemetry, and stores no audio. Audio is sent over an encrypted connection straight from your Mac to OpenAI to become text, then the temporary file is deleted. Blurt operates no server that ever receives your audio or text.
Which languages does Blurt support?
Blurt auto-detects the language you speak — English, Russian, German, and dozens more — and formats the result correctly. You don't have to pre-select a language before you start talking.
Does Blurt run on Intel Macs, and what are the requirements?
Blurt runs on macOS 14 (Sonoma) or later, on both Apple Silicon and Intel Macs. The app is about 5 MB and lives in your menu bar.
How do I start dictating with Blurt?
Hold the Right Option key (remappable) anywhere on your Mac and just talk. When you let go, clean, punctuated text appears at your cursor within about a second. There's nothing to set up beyond adding your OpenAI key.
Stop typing. Start blurting.
