Relay vs Wispr Flow
The core split is privacy and price. Wispr Flow is cloud-based, so your audio is sent to its servers, and it costs $12-15/month after a small free tier, but it's polished and runs on every platform. Relay transcribes on-device, works offline, and is free during beta.

Wispr Flow is the slickest dictation app for newcomers and the only one that spans Mac, Windows, iPhone and Android. That reach comes from doing transcription in the cloud. If you're a Mac user who would rather your voice never leave your machine, and not pay a subscription, that's exactly the gap Relay fills.

What to weigh
Privacy. Wispr Flow routes audio through cloud infrastructure to transcribe and auto-format it. It offers a "privacy mode" and HIPAA-ready enterprise tiers, but the default path sends your speech off-device. Relay does transcription locally, so the privacy question mostly disappears for the core feature.
Try before you commit. Wispr Flow's Pro plan is $144 a year on the annual rate (pricing page). Use the free tier on your own writing for a week or two before paying, and compare it against an on-device tool on the same texts.
Footprint. Relay is a native Tauri app with a single always-on bar, so it stays light on memory and CPU while idle. Wispr Flow is a larger cross-platform desktop app; check its idle resource use in Activity Monitor on your own Mac.
Where Wispr Flow wins outright: cross-platform. If you need the same dictation on Windows or your phone, Relay can't help you (it's Mac only) and Wispr Flow is a sensible pick.
Pick Wispr Flow if…
- You need dictation on Windows, iPhone, or Android too
- You want the most polished, hand-holding onboarding
- Cloud processing and a subscription are fine for you
Pick Relay if…
- You want your voice to never leave your Mac
- You don't want a monthly subscription
- You want dictation that works offline
- You prefer a light, native Mac app

Frequently asked questions
Does Wispr Flow send my voice to the cloud?
Yes. Wispr Flow transcribes in the cloud, so your audio is sent to its servers (running on third-party AI infrastructure). It offers a privacy mode and HIPAA-ready enterprise options, but the default is cloud processing. Relay transcribes on-device, so your voice stays on your Mac.
Is there a free alternative to Wispr Flow?
Yes. Relay is free during its beta and runs locally on Mac. Wispr Flow has a limited free tier (about 2,000 words per week) and then charges $12-15/month. Superwhisper and the open-source VoiceInk are other no-subscription options.
Why is Wispr Flow's free tier limited?
Because cloud transcription has a per-word server cost, Wispr Flow caps the free plan at roughly 2,000 words/week on desktop. On-device apps like Relay don't have that marginal cost, so usage isn't metered.
Which is better for a Mac user?
If you value privacy or want to avoid a subscription, Relay or Superwhisper fit better. Wispr Flow makes the most sense if you also need Windows, iPhone, or Android dictation from the same tool.
