About
Speechify is a Los Angeles-based productivity company that provides an AI text-to-speech application enabling users to listen to any text content — PDFs, ebooks, web articles, Google Docs, emails — at up to 4.5x normal reading speed with natural-sounding AI voices. The product addresses both productivity use cases (consuming content faster) and accessibility use cases (supporting users with dyslexia, ADHD, or visual impairments who process audio more effectively than text). Speechify is the highest-rated text-to-speech app in both the Apple App Store and Google Play and claims over 20 million users globally. The company has expanded from its consumer reading app to enterprise document reading and an AI voice studio with voice cloning for content creation. Founded in 2017 by Cliff Weitzman, who built the app to address his own dyslexia, Speechify raised over $60M from investors including Goff Capital and Kleiner Perkins. It competes with Natural Reader, Audm, and Notta in the text-to-speech accessibility and productivity market.
