AI Summary

Koe is a minimal macOS menu bar app that captures voice input via a hotkey, transcribes it using a cloud service, corrects it with an AI model, and automatically pastes the result into the active application.

How It Works

1
🔍 Discover Koe

You find Koe, a simple voice typing tool for your Mac that turns speech into perfect text without any distracting screens.

2
📥 Install Easily

Download and add it to your Mac with a quick command or from releases, and it runs tiny and fast from the menu bar.

3
🔒 Allow Access

Your Mac asks for permission to use the microphone, watch keys, and paste text – grant them so it can hear you and help type.

4
🔗 Link Services

Connect a voice-to-text service and a smart fixer to polish your words, using simple notes in your home folder.

5
📝 Add Your Words

List special terms like project names in a plain note file, so it recognizes them perfectly next time you speak.

6
🗣️ Press and Speak

Hold the easy key (like Fn), talk naturally, release – and clean, corrected text magically pastes right where you need it!

✅ Type by Voice

Now you dictate emails, code notes, or chats hands-free, with stats on your speed and history right in the menu.

What is koe?

Koe is a zero-GUI macOS voice input app in Objective-C that captures speech via hotkey press-and-hold (default Fn), streams it to Doubao ASR for transcription, corrects it with an OpenAI-compatible LLM, and pastes the polished text into any active field. It solves clunky voice tools by ditching bloated UIs for plain-text config files in ~/.koe/, a simple dictionary.txt for terms, and instant reloads without restarts. Apple Silicon only, with a tiny 15MB footprint.

Why is it gaining traction?

Unlike Electron-heavy apps at 200MB+, Koe stays lean at 20MB RAM, using native macOS APIs for hotkeys, audio, and paste—no Chromium tax. Devs love the editable YAML for ASR tweaks (punctuation, filler removal) and LLM prompts, plus bulk dictionary generation via scripts or AI like Claude. Zero-GUI focus from this zero gui github gem means it just works in the background, with menu bar stats on sessions.

Who should use this?

Mac devs mixing Chinese-English code/docs, like backend engineers dictating Kubernetes configs or frontend folks noting React hooks. Podcasters or writers needing quick, corrected input in Notes, VS Code, or browsers. Skip if you're on Intel Macs or need multi-language ASR beyond Doubao.

Verdict

Solid early pick for voice-first workflows—97 stars and thorough docs make setup straightforward via Homebrew, but 1.0% credibility signals immaturity; no tests visible, single-ASR lock-in. Try it if hotkey-pasted corrections fit; otherwise, wait for OpenAI ASR support.
