HyperVoice vs Wispr Flow
Wispr Flow is a polished cloud-based dictation tool for Mac, Windows, iOS and Android. HyperVoice transcribes on your own machine, works offline, costs less, and never sends your audio to a server.
| Feature | HyperVoice | Wispr Flow |
|---|---|---|
| Where transcription runs | Locally on your machine | Cloud (their servers) |
| Works offline | Yes — after model download | No — requires internet (desktop saves audio and retries once you're back online) |
| Audio leaves your device | Never | Yes, on every dictation |
| Stored on the vendor's servers by default | No — history stays on your device | Transcripts, audio and dictation history (opt-in Privacy Mode stops storage and training) |
| Platforms | Windows, Linux (beta), macOS (Apple Silicon, beta) | Mac, Windows, iOS, Android — no Linux |
| GPU acceleration | Yes — Vulkan (NVIDIA, AMD, Intel) | N/A (cloud-side) |
| Speech recognition engine | OpenAI Whisper (11 model sizes) + Parakeet | Proprietary cloud model (Canto) |
| AI post-processing | Built-in + BYOK (OpenAI / Anthropic) | Built-in |
| Free tier | 500 words/day forever, no card | 2,000 words/week on desktop, 1,000/week on mobile |
| Paid pricing | $49.99 lifetime, or Pro at $7.99/month or $79.99/year | Pro $12/user/month (annual) or $15 monthly; Growth $18 (annual) or $23 monthly; Enterprise custom — no lifetime option |
| Compliance certifications | None | SOC 2 Type II, ISO 27001, HIPAA (all plans) |
If you’ve been using Wispr Flow and find yourself thinking “this is great, but I wish my voice never left my machine”, HyperVoice exists for exactly that reason. Same hotkey-driven UX, same text-at-cursor pipe to any app, but Whisper runs locally on your Windows machine via GPU acceleration.
This page is an honest side-by-side. Wispr Flow is genuinely good, and we’ll tell you where they win.
Where HyperVoice wins
Privacy, by architecture. HyperVoice transcribes audio on your machine using a local Whisper model. Your microphone never connects to a HyperVoice server, and there’s no cloud round-trip on the audio path. (Optional AI cleanup does send the transcribed text, never the audio, to the cloud.) Wispr Flow transcribes in the cloud: your audio goes to their servers, and by default your transcripts, audio and dictation history are stored there. Its opt-in Privacy Mode stops that storage and training. For most users that’s fine. For users in legal, medical, finance, security research, or anyone touching internal company data, audio leaving the machine can be a hard line.
Works offline. Once you’ve downloaded a Whisper model, HyperVoice transcribes without an internet connection. Plane, train, coffee shop with bad WiFi, air-gapped environments: all work. Wispr Flow needs internet to transcribe. On desktop it saves your audio and retries when you’re back online, so you don’t lose the dictation, but the text doesn’t arrive until you reconnect.
Hardware-accelerated locally. HyperVoice ships with Vulkan GPU acceleration that works on NVIDIA, AMD, and Intel graphics cards. Modern GPUs transcribe Whisper Large-v3 in well under a second per dictation. Wispr Flow’s speed depends on your network connection.
A free tier without a weekly ceiling. HyperVoice’s free tier is 500 words per day, forever, no card. Wispr Flow’s free tier is real too: 2,000 words per week on desktop and 1,000 on mobile. That’s roughly half HyperVoice’s weekly allowance, so heavier free use runs into the cap sooner. Try both; neither asks for a card.
Cheaper at every tier. HyperVoice Lifetime is $49.99 one-time. Pro is $7.99/month. Wispr Flow Pro is $12 per user per month on annual billing ($15 month-to-month) with no lifetime option. Over three years, Wispr Flow Pro costs roughly $430–540 against HyperVoice’s one-time $49.99.
You can test the privacy claim yourself. HyperVoice’s speech engine runs OpenAI’s Whisper, an openly published model, on your own machine, so you can switch off WiFi and keep dictating. Wispr Flow’s speech model, Canto, is proprietary and runs in their cloud, so its privacy rests on their policies and controls.
Where Wispr Flow wins
Mobile and Mac maturity. Wispr Flow runs on Mac, Windows, iOS, and Android. HyperVoice runs on Windows, Linux (beta), and macOS (Apple Silicon, beta). The macOS build is signed and notarized by Apple, so it opens with a one-click confirmation, but HyperVoice has no phone build, and its Mac build is newer and less battle-tested than Wispr Flow’s. If you need to dictate on your phone, or you want a more mature Mac experience today, Wispr Flow is the better fit.
Enterprise compliance. Wispr Flow has SOC 2 Type II, ISO 27001 and HIPAA compliance on all plans. If your employer’s procurement team needs vendor security certifications signed and filed, Wispr Flow has those. HyperVoice’s privacy story is architectural (audio stays on your machine), but it’s not the same as a paper trail of audited compliance.
Team plans and meetings. Wispr Flow has team plans: SSO/SAML comes with its Growth plan ($18/user/month annual, $23 monthly) and Enterprise, not with Pro. It also has a meeting Notetaker on Mac and Windows. For a 50-person company rolling out dictation, those matter.

What both do equally well
Both apps share the core dictation UX: global hotkey, press to start recording, release/press again to stop, text appears at your cursor. Both work in any app: code editors, chat clients, browser text fields, email. Both have AI post-processing (clean up filler words, rewrite as a professional email, summarize, etc.).
If you don’t have a strong opinion about local-vs-cloud and you’re already on Wispr Flow, there’s no need to switch. If privacy is the question that brought you here, HyperVoice was built for that answer.

Frequently asked questions
Is HyperVoice a real alternative to Wispr Flow?
Yes, for Windows users specifically. Both tools share the same core UX: press a hotkey, speak, text appears wherever your cursor is, with optional AI cleanup. The fundamental difference is where transcription runs. HyperVoice processes audio locally on your machine; Wispr Flow sends audio to its cloud servers. If you're dictating sensitive content (legal, medical, code, internal company data) or you want to use dictation on a plane, that difference matters.
Why is HyperVoice cheaper than Wispr Flow?
Wispr Flow transcribes in the cloud, so every dictation runs on their servers. HyperVoice runs transcription on your machine's CPU or GPU, so there's no server cost per dictation for speech-to-text. That's why the pricing can be simpler: a free tier of 500 words/day, $49.99 lifetime, or $7.99/month for Pro with HyperVoice Cloud AI cleanup.
What does Wispr Flow do better than HyperVoice?
Phone support and Mac maturity. HyperVoice runs on Windows, Linux (beta), and macOS (Apple Silicon, beta), but Wispr Flow also covers iOS and Android, and HyperVoice has no phone build. Wispr Flow's Mac app is more battle-tested than HyperVoice's Mac beta. If you need to dictate on your phone, Wispr Flow wins. Wispr Flow also offers team plans (SSO/SAML on Growth and above), a meeting Notetaker on Mac and Windows, and SOC 2 Type II, ISO 27001 and HIPAA compliance on all plans, for organizations that need vendor certifications.
Can I migrate from Wispr Flow to HyperVoice?
There's nothing to migrate. Install HyperVoice, set your hotkey (default Ctrl+Shift+Space), and uninstall Wispr Flow when you're satisfied with the switch. Your Wispr Flow dictation history doesn't come across. By default Wispr Flow keeps that history on its servers; HyperVoice keeps its history on your machine.
Does Wispr Flow store my dictation transcripts?
By default, yes. Per Wispr Flow's data controls, your transcripts, audio and dictation history are stored on their servers. Privacy Mode is opt-in: turn it on and they stop storing your dictations and using them for training. HyperVoice stores transcripts only on your local machine in the History tab. Nothing is uploaded to our servers. The one exception is optional AI cleanup, which sends the transcribed text (never audio) to the cloud for processing.
Which is more accurate, HyperVoice or Wispr Flow?
Both produce comparable quality on modern hardware. HyperVoice's accuracy depends on the Whisper model size you pick: Tiny (75 MB) is fast but rougher, and Large-v3 (3.1 GB) is slower but more accurate. Wispr Flow uses its own cloud speech model, Canto, so it may have an edge on casual speech with heavy filler words. For technical vocabulary, try both with your own words. Whisper Large-v3 handles code and acronym-heavy text well.
