The core trade-off

Cloud convenience, or local privacy.

Your voice never travels

Wispr Flow streams your audio to its servers to transcribe it. Open Whisperer does the whole thing on your Mac. For code discussions, client work, or anything under NDA, that difference matters.

Works on a plane

No connection, no problem. Because inference is local, Open Whisperer keeps working with Wi-Fi off — no dropped dictations when the network hiccups, no dependence on someone else's uptime.

It answers out loud

Wispr Flow types your words; the conversation stops there. Open Whisperer closes the loop, speaking your assistant's reply back to you so you can keep your eyes on the problem, not the scrollback.

No meter running

No weekly word cap, no seat pricing, no subscription. It's MIT-licensed and free, so dictate as much as you want and inspect exactly what it does with your audio.

When Wispr Flow might fit better

Fair is fair: if you work across a Mac, a Windows PC, and an iPhone and want one dictation tool everywhere, Open Whisperer won't cover you — it's Apple Silicon only. Wispr Flow's cloud models and cross-platform apps are genuinely convenient if privacy and offline use aren't your priority.

But if you want dictation that never sends your voice off the machine, costs nothing, and speaks your AI's answers aloud, Open Whisperer is built for exactly that. Read the FAQ or the source.

Keep your voice on your Mac.

Free, open source, on-device. macOS on Apple Silicon.
