FluidVoice is a free, open-source dictation app built for macOS 15.0 and later. It's a free alternative to paid tools like MacWhisper and SuperWhisper. FluidVoice turns your speech into text using its own on-device speech engine, called Fluid-1. You can dictate into any text box on your Mac, and it cleans up grammar, punctuation, and formatting as you go — all without sending your audio or text to the cloud.

Key Features:

• Fluid-1 Local Cleanup — a local AI layer that removes filler words, organizes rambling thoughts, fixes text casing, and formats technical terms, all on your device
• Tone That Matches the App — detects the app you're typing into (like Slack, Mail, Xcode, or Cursor) and adjusts the writing style, from casual chat to formal writing or Markdown
• A Wide Range of Speech Models — picks the best model for the job from options like Nemotron Speech 3.5, Parakeet Flash, Parakeet TDT, Cohere Transcribe, Apple Speech, and Whisper
• Fast, System-Wide Dictation — uses CoreML and Metal to run on your Mac's hardware, with response times under 100ms and a global hotkey that works in any app, editor, or terminal
• Built-In Modes for Different Tasks — switch between Write Mode, Command Mode, and Direct Dictation, with support for more than 40 languages

Frequently Asked Questions

How does FluidVoice compare to MacWhisper or SuperWhisper?

MacWhisper and SuperWhisper are both popular tools in our directory. FluidVoice stands apart because it's completely free and open-source (GPLv3). It also goes beyond basic transcription: its local Fluid-1 model rewrites, formats, and adjusts the tone of your text to match whatever app you're typing in.

Does FluidVoice need an internet connection?

No. FluidVoice runs entirely on your Mac. Both the speech recognition and the Fluid-1 cleanup step happen on your device, so no data leaves your machine, and there's no account or tracking required.

Can I use cloud AI models instead?

Yes, if you want to. FluidVoice runs fully offline by default, but it also lets you connect your own cloud API keys, such as OpenAI or Groq, if you'd rather use those.
