Getting Started

FluidVoice can be installed in two ways:

  1. Using Homebrew: Run brew install --cask fluidvoice
  2. Manual download: Visit the GitHub releases page and download the latest version

After installation, grant microphone and accessibility permissions when prompted.

FluidVoice requires:

  • macOS 15.0 (Sequoia) or later
  • Apple Silicon Mac for all speech models
  • Intel Macs supported via Whisper models (from 1.5.1+)
  • ~1 GB disk space for voice models
  • ~3.5 GB disk space for Fluid Intelligence model (optional)
  • Microphone access
  • Accessibility permissions for typing

After installation and permissions:

  1. Open FluidVoice
  2. Go to Settings and set your global hotkey
  3. Complete the onboarding flow to select your speech model
  4. Optionally enable Fluid Intelligence for on-device AI enhancement
  5. Configure your preferred settings

Press your hotkey and start dictating!

Features & Functionality

Fluid Intelligence is a proprietary local AI runtime that powers advanced on-device dictation enhancement including:

  • Smart formatting (quotes, dashes, ellipses)
  • Context-aware capitalization
  • Post-processing for cleaner transcripts
  • Local processing with zero data leaving your Mac

It's completely optional and works alongside any supported speech model.

Command Mode: Lets you control your Mac by voice - launch apps, run shortcuts, trigger system actions, and automate workflows without touching the keyboard.

Write Mode: Lets you write or rewrite text directly in any text field across any app. Select text and rewrite it inline or dictate new content.

Both modes can be activated via the global hotkey or from the menu bar.

Yes! FluidVoice is local-first by default:

  • All speech-to-text processing happens on-device
  • Fluid Intelligence runs entirely locally
  • No data leaves your machine unless you explicitly opt in to cloud AI providers

You can use it completely offline without any internet connection.

Yes! While most speech models require Apple Silicon for optimal performance, Intel Macs are supported via:

  • Apple Speech (built-in)
  • Whisper models (Tiny, Base, Small, Medium, Large)

Intel Macs can still use all features except Fluid Intelligence and certain speech models.

Speech Models

The best model depends on your needs:

  • Parakeet Flash: Lowest latency for English dictation (~250MB)
  • Nemotron Speech 3.5: Fastest multilingual streaming (~670MB)
  • Parakeet TDT v3: Good balance of speed and multilingual support (~500MB)
  • Apple Speech: No download required, uses system languages
  • Whisper: Broadest language support (99 languages), Intel-compatible

Try different models during onboarding to see which works best for you.

Currently, FluidVoice supports the pre-configured models mentioned in our documentation. While we don't support arbitrary custom models, we're always evaluating new models and adding support based on user requests and technical feasibility.

If you have a specific model you'd like to see supported, please create an issue on GitHub.

Speech models vary in size:

  • Apple Speech: Built-in (no download)
  • Whisper Tiny: ~75MB
  • Parakeet Flash: ~250MB
  • Parakeet TDT v3/v2: ~500MB
  • Nemotron Speech 3.5: ~670MB
  • Cohere Transcribe: ~1.4GB
  • Whisper Large: ~2.9GB

Fluid Intelligence requires ~3.5GB if enabled.

Privacy & Security

By default, all voice processing happens on your Mac:

  • Speech-to-text: On-device using local models
  • Fluid Intelligence: On-device AI enhancement
  • Text processing: On-device formatting

Only if you explicitly enable cloud AI providers (OpenAI, Groq, etc.) will your data be sent to external services. All API keys are stored securely in macOS Keychain.

FluidVoice collects minimal anonymous data to track app health:

  • App version and build number
  • macOS version
  • General feature usage (low-cardinality)
  • Approximate usage ranges
  • High-level success/error outcomes

Never collected: Voice data, raw audio, transcribed text, selected text, prompts, AI responses, terminal commands, window titles, file paths, clipboard content.

You can disable analytics at any time in Settings.

Yes, FluidVoice is designed with privacy in mind:

  • No personal data processing by default
  • Opt-in analytics with clear controls
  • Local-first processing architecture
  • No user tracking or profiling

The app follows privacy-by-design principles and doesn't collect identifiable personal information.
