Whisper vsWispr Flow
Wispr Flow is cloud-based and charges monthly. Whisper runs a GPU-accelerated engine entirely on your device — an hour of audio in about a minute — for a one-time $29 payment.
Cloud-fast — without the cloud
Whisper's engine is GPU-accelerated (Metal on Mac, Vulkan on Windows and Linux). On Apple Silicon it transcribes about an hour of audio in a minute, and short dictation is on screen the moment you stop talking — punctuation and capitalization included.
Wispr Flow feels fast too, but it still has to reach a server and back. Whisper never leaves your machine, so there's no network round-trip — and it keeps working with the Wi-Fi off.
The Cloud Problem
Wispr Flow processes your voice in the cloud. Every word you speak is sent to their servers, processed by their AI, and stored. While they're SOC 2 certified, your data still leaves your device.
Whisper is different: 100% offline processing. Your voice is transcribed directly on your Mac and never touches any server. True privacy, not compliance theater.
Why Choose Whisper Over Wispr Flow?
True Privacy
SOC 2 compliance means Wispr Flow handles your data carefully—but they still have it. Whisper never sees your data because it never leaves your Mac.
No Subscriptions
Wispr Flow charges monthly, forever. Whisper is $29 once. After a few months, Whisper has already paid for itself.
Works Anywhere
No WiFi? No problem. Whisper works on planes, in remote areas, during internet outages. Wispr Flow stops working without a connection.
