One-time payment. Free quick mode forever. AI mode and Silent mode unlock with the licence. 14-day trial of Pro, 14-day refund.
$12/month billed annually, or $15/month billed monthly. Free tier capped at 2,000 words/week (1,000 on iPhone). 14-day Pro trial with no card required.
If you used Wispr Flow for two years, you'd pay $288, almost ten times Murmur's lifetime cost. After three years, the gap is wider. The lifetime model is the bet that you don't want to keep paying for software you've already learned to use.

Cross-platform. Wispr Flow runs on Mac, Windows, and iOS. Murmur is Mac-only and likely to stay that way for a while. If you split your time across platforms or want dictation on your phone, Wispr Flow is the right tool today.
Maturity and brand. Wispr Flow is a more established product with a larger user base, a marketing budget, and an active engineering team. Both apps transcribe 100+ languages (Wispr in the cloud, Murmur on-device via Whisper Large), so engine-level coverage is similar; Wispr Flow's edge is the polish layer (per-app tone, formatting) being more battle-tested across thousands of paying customers.
API costs are bundled. Wispr Flow's subscription includes the cost of the AI calls. Murmur asks you to bring your own Claude API key, which means you also pay the Claude API bill (typically a few dollars a month for normal use). For very heavy users, the bundled pricing may be more predictable.
Audio never leaves your Mac. Murmur runs Whisper locally via Apple's MLX framework. There is no streaming, no cloud transcription, no audio upload. Wispr Flow uses cloud transcription by design, so your audio is sent to their servers. For a lot of users (lawyers, doctors, people in regulated industries, people who'd rather not), that distinction is the whole pitch.
Active-window-only screenshots. When Murmur captures a screenshot for AI polish, it captures the focused window only. Never the full screen, never other apps, never your desktop. The opt-in is per request, on your gesture; never automatic, never continuous, never stored. Wispr Flow's privacy story is different and worth reading their docs on directly before deciding.
One-time price. $29 once versus $144 every year. Two months of Wispr Flow Pro costs more than a lifetime of Murmur. After three years, you've paid $432 to Wispr Flow versus $29 to Murmur. The math is dramatic.
The gesture. Hold the hotkey to dictate. Double-tap to polish with Claude. Double-tap silently to let Claude write from the screenshot alone. One hotkey, three modes, picked per utterance. Wispr Flow's interaction model is single-mode and similar across utterances.
Direct to the AI provider. Murmur's AI mode talks directly to api.anthropic.com using your own API key. There's no Murmur server in the middle, no proxy, no metadata collection by us. Wispr Flow routes through their infrastructure by design.
No "we've updated our pricing" email. Subscription pricing changes. Lifetime licences honour the version they were sold against. If Murmur ever moves to a subscription, your $29 licence keeps working forever.

Yes, dramatically. Murmur is $29 once. Wispr Flow Pro is $144 per year. Two months of Wispr Flow costs more than a lifetime of Murmur. After three years of Wispr Flow, you've paid almost 15x what you'd pay for Murmur.
No. Murmur runs Whisper locally on your Mac via Apple's MLX framework. Audio never leaves the device. Wispr Flow uses cloud transcription, so your audio is sent to their servers for processing. If audio confidentiality matters to you, this is the most important difference between the two.
Yes. Murmur installs in minutes and uses Right Command as the default hotkey, so it sits alongside Wispr Flow during your trial. Cancel your Wispr subscription whenever you're confident. Your vocabulary and snippets need to be re-entered manually; there's no auto-import yet.
Not yet. Murmur is Mac-only (macOS 12+, Apple Silicon). Wispr Flow's cross-platform availability is its strongest argument over Murmur. If you need to dictate on Windows or iOS today, Wispr Flow stays the right pick.
Murmur captures only the active window, never the full screen, never other apps, never your desktop. Screenshots are sent only on your gesture, only in AI mode, and discarded on receipt. Wispr Flow's privacy policy describes broader system access; review their docs to compare directly.
Possibly. But your lifetime licence honours the version you bought it against. If Murmur ever moves to a subscription, your $29 licence keeps working forever. There's no "we've updated our pricing" email three years from now.
One hotkey, three modes. Hold Right ⌘ to dictate locally (Quick mode). Double-tap and hold to send the transcript and a screenshot to Claude for a polished reply (AI mode). Double-tap without speaking to send just the screenshot and let Claude write the reply from context (Silent mode).
Quick mode dictation is free forever. Install Murmur, hold Right ⌘, see if the gesture clicks. If you want AI mode and Silent mode, the Pro licence is $29 once with a 14-day trial.
