Wispr Flow

Wispr Flow is a San Francisco-based AI voice dictation platform that converts natural speech into polished, formatted text across any application at roughly 220 words per minute - about 4x faster than typing. Built by two Stanford AI researchers, the company has quietly become the voice layer that 270 Fortune 500 companies rely on, combining a 10% word error rate (vs. 27% for OpenAI Whisper), 100+ language support, and context-aware formatting that automatically adjusts tone and style based on the active app. With $81M raised and a $700M valuation as of late 2025, Wispr Flow is racing to become the default voice-first operating system for a billion users.
