Willow
Willow is a San Francisco startup building voice-first interfaces that turn natural speech into polished text across every app on Mac, Windows, and iPhone. Founded in 2024 by Stanford dropouts Allan Guo and Lawrence Liu and backed by Y Combinator, Willow promises roughly 3x the accuracy of built-in dictation with ~200ms response time, automatic filler-word removal, style-matching, and an AI mode that reshapes rough spoken notes into finished messages. The company raised $4.2M in seed funding and has grown roughly 50% month over month, with early enterprise users including Uber, Heidi Health, and Zego.
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.
