Speechify

World leader in text-to-speech with 1000+ natural voices

Speechify is the world's leading voice productivity platform, founded in 2017 in Miami by Cliff Weitzman (who has dyslexia) and his brother Tyler. With over 50 million users and the prestigious 2025 Apple Design Award, Speechify has become the reference in text-to-speech. Speechify's strength lies in its exceptional library of over 1000 natural and expressive AI voices, including celebrity voices like Snoop Dogg, MrBeast, and Gwyneth Paltrow. The service supports over 60 languages with regional accent variations. Beyond simple reading, Speechify offers advanced features: synchronized highlighting during listening, physical document scanning (OCR), voice dictation 5x faster than typing, conversational AI assistant, automatic summary and quiz generation, podcast creation, and offline listening. The complete ecosystem includes iOS, Android, and Mac apps, as well as extensions for all browsers (Chrome, Edge, Firefox, Safari). Native integration with Google Drive, Dropbox, and OneDrive makes accessing your documents easy.
