Who each one suits

FluidVoice

Superwhisper

Worth knowing

FluidVoice

  • Mac only for now: iPhone and Windows versions are listed as coming soon, with a waitlist.
  • It requires macOS 15.0 or later, and Intel Macs are limited to the Whisper and Apple Speech models.
  • Fluid Intelligence is a separate, privately maintained runtime and is not part of the open-source code.
  • Choosing OpenAI, Groq or another cloud provider for enhancement sends text off the Mac.

Superwhisper

  • AI-powered modes, cloud voice models, file transcription and speaker separation all need Pro.
  • The Free plan is limited to 2 modes, and those run without AI processing.
  • Cloud voice models send audio to hosted servers; only the local models keep audio on the device.
  • A Linux version is listed as coming soon and is not yet available.

Key features

FluidVoice

System-wide dictation
Hold one global hotkey and speak, and the text is typed into any text field through macOS accessibility APIs. A live preview overlay shows words as they are recognized.
On-device speech models
Nemotron Speech 3.5, Parakeet, Cohere Transcribe, Apple Speech and Whisper models run locally. Language coverage depends on the model, from English only up to 99 languages with Whisper.
Fluid Intelligence
An optional local AI runtime, about a 3.5 GB download, runs the Fluid-1 model to strip filler, fix capitalization and format text with no cloud service or API key.
Write Mode and Command Mode
Write Mode drafts new text or rewrites a selection in any text field. Command Mode launches apps, runs shortcuts and triggers system actions by voice.
Per-app prompts
Assign different prompt sets to different apps so the tone follows the context, for example casual in Slack and formal in Mail.
Optional cloud AI enhancement
Post-processing can instead use OpenAI, Groq or a custom provider with your own API key, which is stored in the macOS Keychain.

Superwhisper

Dictation in any app
Speak and have the text typed into whatever app is in front of you, such as Slack, Gmail, Notion or a code editor. More than 100 languages and dialects are supported.
Local models that work offline
Whisper models run entirely on your device and are free to use without limits, so dictation works with no connection and audio is not uploaded.
Cloud voice models on Pro
Pro adds hosted voice models such as S1-Voice, Nova and Scribe, along with real-time transcription. With these models audio is sent to hosted servers.
Modes
A mode sets how speech is processed, from plain transcription to AI modes that rewrite it for a context such as email. Free allows 2 modes without AI; Pro is unlimited.
Meetings and file transcription
Records meetings and produces notes, and Pro adds system audio recording, speaker separation and transcription of audio or video files.
Custom vocabulary
Add names and terms the models tend to get wrong, plus text replacements. Both are included on the Free plan.
