OpenFlow brings free, local voice dictation to Mac
OpenFlow is a free, MIT-licensed macOS menu bar app that transcribes speech to text entirely on-device using whisper.cpp — no account, no subscription, no internet. It's a direct open-source alternative to Wispr Flow ($8/month), offering the same hotkey-to-dictate workflow with zero data leaving your machine.
// ANALYSIS
The "why pay for cloud when whisper.cpp runs locally" argument has never been stronger, and OpenFlow is the cleanest macOS implementation of it yet.
- –Uses whisper.cpp bindings (SwiftWhisper) with three model sizes (Tiny/Base/Small) to let users tune the speed-vs-accuracy trade-off
- –Runs entirely on Apple Silicon or Intel Macs with macOS 14+, activates via a global shortcut from any app, and inserts transcribed text at cursor position
- –Wispr Flow's $8/month subscription is its entire value proposition — OpenFlow eliminates it at the cost of context-awareness and cloud polish
- –Built in Swift/SwiftUI with custom text-replacement rules, custom correction macros, and a ~3 MB install footprint
- –The open-source whisper-for-dictation space is crowded (VoiceInk, open-wispr, VoiceTypr), but OpenFlow's clean UX and MIT license make it the most fork-friendly entry point
