Wispr Flow vs Superwhisper: Which AI Dictation Tool Should You Use?
Wispr Flow and Superwhisper are the two best AI dictation tools available right now. Both transcribe speech with excellent accuracy, both work system-wide on Mac, and both use AI to clean up your output. But they make different trade-offs — and for many users, the right choice is obvious once you know where they diverge.
This comparison covers every decision-relevant dimension: platform support, pricing, offline capability, free plan, shortcut UX, AI correction quality, and custom vocabulary. Skip to the verdict table if you're in a hurry.
Platform Support: The First Decision Filter
This is the fastest way to eliminate one tool from consideration.
Wispr Flow supports Mac, Windows, iOS, and Android. Your subscription syncs across devices. If you dictate on a work MacBook and a personal Windows PC, or if you want to capture voice notes on iPhone during a commute, Wispr Flow covers all of it from one account.
Superwhisper is Mac-only. No Windows client. No mobile app. If you ever need to dictate outside of macOS, Superwhisper can't help.
Decision rule: If you use any non-Mac device for serious work, Wispr Flow wins by default. If you're Mac-only, continue comparing.
Pricing Comparison
| Plan | Wispr Flow | Superwhisper |
|---|---|---|
| Free tier | 2,000 words/week | Trial only |
| Paid monthly | ~$15/month | ~$8/month |
| Paid annual | ~$12/month | ~$8/month (single price) |
| Student discount | Yes (50% off) | No |
⚠️ Prices shown are for reference only and may change. Always verify on the official Wispr Flow pricing page and the Superwhisper website before purchasing.
Superwhisper is meaningfully cheaper at around $8/month with no annual/monthly split. Wispr Flow charges more — approximately $12/month annual or $15/month monthly. The higher price reflects the broader platform support and unlimited cross-device dictation.
If you're a Mac-only user who dictates heavily, Superwhisper's lower price plus local model advantage may justify the choice. If you need multi-platform or you value the free tier to test before committing, Wispr Flow is worth the premium.
Offline Mode: The Biggest Technical Difference
This is where Superwhisper has a genuine, meaningful advantage.
Superwhisper can run an OpenAI Whisper model locally on your Mac. You choose from multiple model sizes (tiny, base, small, medium, large) — larger models are more accurate but slower and require more RAM. On an M2 or M3 Mac, the medium model runs in near-real-time. On an M4 MacBook Pro, even the large model is fast enough for practical use. Zero internet required. Zero server round-trip.
Wispr Flow processes everything server-side. There is no offline mode. Every transcription requires an active internet connection with low enough latency to feel immediate.
The practical implications:
- Sensitive environments (legal, medical, classified settings): Superwhisper with a local model keeps audio entirely on-device. Wispr Flow sends audio to their servers, even with Privacy Mode enabled.
- Poor connectivity (airplane, rural areas, hotel Wi-Fi): Superwhisper keeps working. Wispr Flow degrades or fails.
- Latency: Superwhisper local processing can be faster than Wispr Flow's network round-trip on a good hardware/model combination. Server-side, Wispr Flow is typically under one second.
Accuracy: Closer Than You'd Expect
Both tools achieve high accuracy on clean audio with natural speech. Raw accuracy isn't the differentiator — AI correction is.
Superwhisper's accuracy depends on which Whisper model you select. The large model is OpenAI's highest-accuracy open-source model and produces transcription quality that rivals or exceeds most commercial services for general speech. With custom vocabulary and prompt-priming, it can be tuned for specific domains.
Wispr Flow's accuracy is excellent out of the box and doesn't vary by model — you get what you get. The AI correction layer compensates for raw transcription errors by using context to fix likely mistakes (proper nouns, technical terms with common homophones). Adding words to the custom dictionary eliminates most domain-specific errors.
Real-world result: For most users speaking in a quiet environment, accuracy is equivalent. Superwhisper's edge comes in specialized domains where you can select a larger, fine-tuned model. Wispr Flow's edge comes in the AI post-processing quality — its output sounds more like edited prose and less like raw speech.
Free Plan and Trial
Wispr Flow offers a permanent free tier: 2,000 words per week on desktop (Mac and Windows), 1,000 words per week on iOS. This resets every Sunday at midnight Pacific. The free tier is a real, ongoing plan — not a countdown. Every new user also gets a 14-day Pro trial with unlimited dictation to experience the full product.
Superwhisper does not have a permanent free tier. It offers a trial period, after which you need to subscribe. There is no ongoing free quota.
For users who want to test before committing, Wispr Flow's combination of a 14-day Pro trial plus a permanent 2,000 words/week fallback is the more generous onboarding.
Shortcut UX and Activation Feel
Both tools activate via keyboard shortcut and work system-wide in any text input field.
Wispr Flow's default is a double-tap of the right Shift key — hold to dictate, release to process and type. The double-tap prevents accidental activation but takes a few days to feel natural. Customizable to any hotkey combination.
Superwhisper's default is similar — hold to dictate, release to process. Customizable to function keys, modifier combos, or dedicated keys.
The feel is largely equivalent. Both inject text at the cursor position in under two seconds from release. Superwhisper's local model can reduce this to nearly instant on high-end hardware. Wispr Flow's server-side processing adds a network round-trip that is barely perceptible on fast Wi-Fi but noticeable on a slow connection.
AI Correction Quality
Both tools use AI to clean up raw transcription. The outputs differ subtly.
Wispr Flow's AI layer is tuned for professional communication — emails, messages, documentation. It removes filler words aggressively, normalizes punctuation, and produces output ready to send without review. The Command Mode (Pro) lets you give editing instructions mid-session.
Superwhisper's AI layer is also strong but tends to be slightly more conservative in correction — useful if you want your natural speech rhythms preserved. Superwhisper also lets you choose AI provider (OpenAI, local LLM) for the correction pass, which gives advanced users more control.
Custom Vocabulary
Both tools support custom dictionaries for adding names, technical terms, and abbreviations.
Wispr Flow's dictionary syncs across all your devices on the same account. Pro teams can share a dictionary and snippets library across seats — useful when everyone on a team needs the same product names and brand terms recognized correctly.
Superwhisper's vocabulary is local to the machine. No cloud sync, no team sharing.

No. Superwhisper is Mac-only. If you need dictation on Windows, iOS, or Android, Wispr Flow is the only option between these two tools.
No. Wispr Flow processes audio server-side and requires an active internet connection. Superwhisper can run OpenAI Whisper models locally on your Mac with zero network dependency.
For general speech in quiet conditions, accuracy is similar. Superwhisper's advantage is model selection — on an M2 or M3 Mac, you can run the large Whisper model locally for best-in-class accuracy. Wispr Flow compensates with a strong AI correction layer that produces cleaner final output.
Wispr Flow. It offers a permanent free tier of 2,000 words per week on desktop, plus a 14-day Pro trial with unlimited dictation. Superwhisper does not have a permanent free tier.
Superwhisper is cheaper at approximately $8/month with no annual pricing distinction. Wispr Flow costs approximately $12/month on an annual plan or $15/month monthly. Always verify current pricing on each vendor's official pricing page before purchasing.
Technically yes, but there's no practical reason to — their system-wide hotkeys may conflict. Most users pick one and stick with it. Run both free trials and choose based on which activation feel and output quality fits your workflow better.
