# Dictation App for Mac — Mumbli

> A lightweight macOS dictation app that lives in your menu bar. Hold Fn to dictate into any text field with AI transcription and polishing.

# Dictation app for Mac

Mumbli is a menu bar dictation app for macOS. It stays out of your way until you need it — then turns speech into clean text in under a second.

## Menu bar, not another window

Mumbli runs as a menu bar app. No Dock icon, no window to manage. Click the menu bar icon to see your dictation history, adjust settings, or quit. That's it.

When you're dictating, a small overlay appears near your cursor — just enough to know Mumbli is listening. It disappears the moment you stop.

## Two activation modes

| Mode           | How               | When to use                                                   |
| -------------- | ----------------- | ------------------------------------------------------------- |
| **Hold mode**  | Press and hold Fn | Quick phrases, replies, short dictation                       |
| **Hands-free** | Double-tap Fn     | Longer dictation, thinking out loud, when your hands are busy |

Both modes are always available. No configuration needed.

## AI-powered, not basic

Most dictation tools give you raw speech-to-text. Mumbli adds a polishing layer:

* **Filler words removed** — "um", "uh", "like" are stripped automatically
* **Self-corrections applied** — "Tuesday, wait, Wednesday" becomes "Wednesday"
* **Grammar cleaned up** — Punctuation, capitalization, and sentence structure
* **Your voice preserved** — The polisher cleans, it doesn't rewrite

## Use cases

<CardGroup cols={2}>
  <Card title="Universal text input" icon="keyboard">
    Any app, any text field. Browser, email, Slack, IDE, terminal — if there's a cursor, Mumbli works.
  </Card>

  <Card title="Accessibility" icon="universal-access">
    For users with RSI, physical limitations, or temporary injuries. Reliable enough to be your primary input method.
  </Card>

  <Card title="Thinking out loud" icon="brain">
    Speak a stream of consciousness into a note. The polisher cleans it up enough to be readable without losing the raw thought.
  </Card>

  <Card title="Quick replies" icon="reply">
    In a messaging app or email, speak your reply instead of typing. Faster for anything longer than a few words.
  </Card>

## Dictation history

Every dictation is saved locally with a timestamp. Access it from the menu bar dropdown:

* Click any entry to copy it to your clipboard
* Most recent entries appear first
* History persists across app restarts
* All data stays on your machine

## Safety built in

Mumbli guards against LLM hallucination with three layers:

1. **XML boundaries** between system instructions and your speech
2. **Injection-hardened prompts** that prevent the LLM from inventing content
3. **RepetitionGuard** that catches runaway output and falls back to raw transcription

## Requirements

* **macOS 13.0+** (Ventura or later)
* Your own API keys for transcription (ElevenLabs, Groq, or Deepgram) and polishing (OpenAI or Groq)
* Microphone, Accessibility, and Input Monitoring permissions
