Privacy-First Mobile Speech-to-Text App

C7/10April 6, 2026
WhatA fully local, on-device speech-to-text app for iOS and Android that runs modern models like Parakeet without sending audio to the cloud.
SignalA commenter explicitly states that while desktop local STT is getting good, there is no free or high-quality fully local option for mobile — native phone dictation is not fully local and not as accurate as the latest open models.
Why NowMobile chips (A17 Pro, Snapdragon 8 Gen 3) now have enough NPU performance to run compact models like Parakeet v3 at real-time speed, and Apple's on-device ML frameworks have matured to support this.
MarketHundreds of millions of smartphone users who dictate texts, notes, and messages daily; the mobile keyboard/input market is massive. Competitors like Wispr Flow are desktop-only; Google and Apple built-in dictation still phones home for best results.
MoatModel optimization for specific mobile chipsets and tight OS integration create switching costs; first mover on mobile local STT with a quality UX could build a strong user base before platform vendors catch up.
