FluidVoice

FluidVoice is a free, open-source macOS voice-to-text app that uses local speech models for fast, offline transcription and an optional on-device AI layer (Fluid-1 / Fluid Intelligence) to post-process and polish transcripts—fixing punctuation, capitalization, dates/numbers, structure, and adapting tone per app—so your dictation types into any app as clean, context-appropriate text with zero data leaving your Mac by default; you can also opt to use cloud AI providers (OpenAI, Groq, or custom) if you need additional enhancements, making it ideal for privacy-conscious users, heavy typists, and anyone who wants faster, more natural writing on macOS.
