Willow Voice vs Hearsy: Cloud Subscription vs Local One-Time Purchase

Willow Voice is a cloud-first AI dictation app for Mac, Windows, and iPhone. Press the Fn key in any application, speak naturally, and Willow transcribes and formats your text with context-aware AI that adapts to the app you're typing in.

Willow Voice is a Y Combinator-backed startup that has grown to roughly 1,300 monthly brand searches. It positions itself as a fast, accurate cloud dictation tool that works across platforms including Mac, Windows, and iOS with a custom voice keyboard. The iOS keyboard lets you switch between voice and text input without reverting to Apple's default keyboard.

Willow's context-aware AI understands where you're typing and adjusts formatting accordingly — emails get professional structure, Slack messages stay casual, and code editors get technical formatting. You can define custom vocabulary terms and create different writing styles for app categories like work, messaging, and email. Willow claims sub-1 second latency and supports over 100 languages.

As of March 2026, Willow offers a free tier of 2,000 words per week. Paid plans run $12-15/month for unlimited dictation. The app is primarily cloud-based, sending recognized text to servers for processing. An offline mode is available but must be manually enabled and is not the default experience. Willow holds SOC 2 compliance and claims HIPAA readiness for enterprise customers.

Hearsy is a menu-bar dictation app that runs entirely on your Mac. Press a global hotkey from any app, speak, and transcribed text is pasted at your cursor. No internet connection is used during transcription. Audio is processed in local RAM by one of two AI engines: Parakeet TDT for English (under 50ms latency) or Whisper Large V3 for 99 languages. Optional AI cleanup runs locally via Qwen 2.5 by default, with no API call required.

Willow Voice is cloud-first: audio is captured locally, sent to cloud servers for processing, and transcribed text is returned. No audio files are stored on Willow's servers — audio stays on-device for re-transcription. Transcript content and contextual awareness data are stored locally on-device, not on Willow servers.

Willow offers two privacy modes. Private Mode (the default) means no dictated text is collected and transcripts stay local. The optional 'Help Willow Improve' mode anonymizes text for training but does not collect audio. Data in transit uses TLS encryption and data at rest is encrypted.

Willow holds SOC 2 compliance and offers HIPAA compliance for enterprise customers with signed MSA/DPA and SSO/SAML support. An offline mode provides fully local processing but must be manually enabled.

Hearsy processes everything locally by default — no network transmission during transcription, no privacy policy to evaluate, and no server infrastructure involved.

Willow Voice claims sub-1 second latency and sub-200 millisecond processing time for its cloud transcription. In practice, speed depends on network quality — on a fast connection, text appears nearly instantly. On slow or congested networks, latency increases. The offline mode's local model may be slower than the cloud version.

Hearsy's Parakeet TDT processes English audio in under 50ms on Apple Silicon — local processing with no network round-trip. Whisper Large V3 in Hearsy takes 1-2 seconds, still entirely local.

For most daily use on a good connection, Willow Voice is fast enough. The gap shows on poor connections, during travel, or when you need guaranteed low latency regardless of network conditions.
