Where Willow Voice pulls ahead
These two are near-twins: both cloud-only, both 2,000-words-a-week free, both fast and polished on the same three platforms. Willow’s edge is accuracy and speed. It posts the highest out-of-box number we measured (99.0% vs Wispr Flow’s 96.5%), streams audio as you speak for 0–2s results, and adapts its style per app without you picking a mode. On accented and casual speech it is a touch cleaner.
Where Wispr Flow pulls ahead
Wispr Flow answers with privacy controls and developer features. It offers a privacy mode with zero data retention — something Willow doesn’t expose — alongside customisable hotkeys, including mouse-button triggers, and a dedicated vibe-coding mode for variable names. Its free tier matches Willow’s 2,000 words a week. Where it falls behind is raw accuracy and a tendency to slip on brand terms ("Tauri" → "Atari"); neither app has any offline mode.
