Made for people who work with AI
You already think out loud to a model. Halvox is the fastest way to get the words there: press the hotkey, talk, and your prompt lands in whatever you are working in, cleaned up in your own voice if you want it.
Speak a rambling thought and get back a tight prompt. Dictate straight into Claude, Cursor, or the terminal. Give your agents free, on-device transcription over the CLI and MCP. It runs on your Mac, and it is yours.
Ramble at it.
Get back a clean prompt.
Everything it does
-
Press the hotkey, talk
Option Space works in any app, or record any key you like. Press to toggle or hold to talk, and a floating pill shows your live level.
-
Lands where you point
Words auto-paste where you are typing. A finished transcript can land anywhere: press Insert by clicking, then click any text field in any app.
-
Fast on your Mac
Local through whisper.cpp, with the encoder on the Neural Engine on Apple Silicon. A three minute recording lands in about fourteen seconds, even with Halvox in the background.
-
Files in, transcripts out
Drop in mp3, m4a, wav, aiff, mp4 or mov, or right-click a recording in Finder and Open With Halvox. Live read-back, plain text and SRT export, free forever.
-
Understands real accents
Built by a non-native speaker. Accurate mode runs the stronger model, measurably better on accented English, and your dictionary pins the spellings you mean.
-
Speaks your language
Understands eight languages plus auto detect, and the interface itself ships in eight. The full list is just below.
-
Cleaned up, in your words
Six built-in styles on your own Claude key: raw, clean, Slack, email, bullets, agent prompt. Save your own named styles too.
-
Built for your agents
A free CLI and an MCP server give Claude Code and Codex on-device transcription, no key required.
-
Private, and yours to keep
No account, no cloud, no telemetry; audio never leaves your Mac. Every transcript is saved locally and searchable, with retention you control.
Understands eight languages.
Speaks them too.
- Auto detect
- English
- Spanish

- 日本語
- 简体中文
Menus, settings, and every label follow your Mac's language, automatically.
Built for your terminal and your agents
Halvox ships a command line and an MCP server, so your terminal and your coding agents get the same on-device transcription the app uses. Free, private, no API key, and the audio never leaves your Mac.
Pipe speech into anything
One command turns a recording into text on stdout, ready to pipe into a file, a script, or a prompt. Add --srt for subtitles.
$ halvox transcribe talk.m4a > notes.txt Transcription your agent can call
Run the server and Claude Code or Codex can transcribe audio and read your history as tools, on device, no key required.

FAQ
Never. Transcription runs locally through whisper.cpp. The only optional network call is the cleanup pass, which sends text, not audio, and only on your own key.
No. Dictation and file transcription work without one. Cleanup is optional and runs on your own Anthropic key, which costs cents a month at personal volume.
Yes. Dictate straight into Claude, ChatGPT, Cursor, or the terminal, since Halvox types wherever your cursor is. It also ships a CLI and an MCP server that give Claude Code and Codex free, on-device transcription.
Any Mac on macOS 14 or later, Apple Silicon or Intel, with the same accuracy on both. On Apple Silicon the encoder runs on the Neural Engine.
Really. $29 at launch, $39 after, one license for two of your Macs, and a full year of updates included. The app is yours forever; after the year, staying current is an optional upgrade, never a renewal.
Dictation pauses until you buy a license. File transcription keeps working, free, forever.
Apple's review guidelines block the API that lets an app type into another app. A store build could only copy to the clipboard, which is why Halvox ships directly.
Spoken: English, Spanish, French, German, Portuguese, Italian, Japanese and Chinese, plus auto detect, and every one of them runs a strong multilingual model on device. Separately, the interface itself ships in those same eight languages and follows your Mac's language setting.
That question is personal here: Halvox is built by a non-native English speaker. Accurate dictation mode runs the stronger model, which is measurably better on accented speech, and the custom dictionary makes sure your names and terms always come out spelled the way you want.
