Five apps Mac users actually use, ranked by what they're best at. Apple Dictation is free and basic. Murmur is $29 lifetime with AI polish. Wispr Flow, SuperWhisper, and MacWhisper each have a niche where they win.

Almost every voice-to-text app on Mac uses one of two engines: Apple's built-in dictation model, or OpenAI's Whisper (often a quantised on-device version). The accuracy difference is real: Whisper is meaningfully better at technical terms, accents, and noisy environments.
From there, the products diverge into three shapes:
$0: Apple Dictation. Press fn twice. Speak. Decent on short replies. Weaker on technical terms. No AI polish, no formatting, no Markdown awareness, no custom prompts. The "I just need basic" choice.
$29 lifetime: Murmur. Whisper-based local transcription, AI polish via your Claude API key, single hotkey with three gestures (tap / double-tap / long-hold). Audio stays local. The "I want the polish without the subscription" choice.
$144/year: Wispr Flow. Cloud transcription, per-app tone profiles, polished output across Slack, Gmail, Notion, anywhere. Most polished output of any app on this list. Audio leaves your machine. The "I'll pay for convenience" choice.
Each links to a head-to-head: vs Wispr Flow, vs SuperWhisper, vs VoiceInk, vs MacWhisper, vs Aqua Voice, vs Apple Dictation.
Whisper-based apps clear ~95% accuracy on clean speech with native English. Apple Dictation lands closer to ~90% on the same input. The gap widens fast on technical terms (programming, medical, legal vocabulary), uncommon names, and accents.
For a sense of scale: dictating a 200-word email might produce 0-2 errors with a Whisper-based app, 4-8 errors with Apple Dictation. The fixes take 10-30 seconds either way, so for short replies the difference is small. For longer dictations, it stacks up.
None of these are perfect. All of them benefit from re-reading the output before sending. Dictation is fast input, not error-free input.
Worth knowing before you pick:
If your dictation routinely covers client work, deals, salaries, code, or anything you'd hesitate to paste into a public form, on-device matters more. If you're dictating personal notes and Slack jokes, the cloud option is fine.
For free, Apple Dictation. For lifetime AI polish, Murmur ($29). For the deepest cross-app rewrite engine, Wispr Flow ($12/mo). For multilingual power use, SuperWhisper ($249.99). For transcribing audio files, MacWhisper (€59).
Apple Dictation is free and built into macOS. Whisper-based apps (Murmur, MacWhisper, VoiceInk) charge $25-$249 lifetime. Subscription apps (Wispr Flow, Aqua Voice) charge $96-$144 per year.
Apple Dictation is decent for short replies, weaker on technical vocabulary. Whisper-based apps (Murmur, MacWhisper, SuperWhisper, VoiceInk) use OpenAI's Whisper model and handle accents, technical terms, and noisy environments noticeably better.
Yes. Mac voice-to-text apps insert text wherever the cursor is, the same way typing does. Slack, Gmail, Notes, Word, Cursor, anywhere.
Apple Dictation streams words as you speak. Wispr Flow and Aqua Voice stream too. Whisper-based apps (Murmur, VoiceInk, SuperWhisper) wait until you finish, then transcribe and paste in one go. The wait is usually a second or two.
Murmur is the cheapest Whisper-based dictation app on Mac with built-in AI polish. Quick mode is free; the $29 licence unlocks AI mode and Silent mode.
