SuprFlow is a customization-first, privacy-centered speech-to-text dictation app for Mac. Built as an AI harness — a layer that sits on top of AI models — it lets you bend voice-to-text to work exactly how you need it.
Unlike most dictation tools that send your audio to the cloud, SuprFlow runs the full pipeline locally on your Mac. Nothing leaves your machine. No account required, no server, no subscription.
Key features:
100% on-device processing powered by WhisperKit
Works offline, fully private
Flexible AI model support — use built-in models or swap in your own
Works in any app: Slack, Gmail, VS Code, Notion, and more
One-time purchase at $49.99 — yours forever
Community-driven roadmap: you shape what gets built next
Two founders with 40 years of combined experience building something you can truly make your own.
