Speechify is a text to speech app that reads text aloud in natural sounding voices. Cliff Weitzman started it after building a tool to help with his own dyslexia while at university. It works with PDFs, web pages, emails, books and photos of printed pages.
Users can change reading speed, pick from many voices and languages and follow along with highlighted text. The app works on the web, as a Chrome extension, on Mac, and on iOS and Android. Other tools include voice typing, AI summaries and a voice studio for making voiceovers and dubbing videos. Files and reading progress sync across devices, so a user can start listening on a laptop and finish on a phone.
There is a free version with basic voices. The Premium plan unlocks higher quality voices, faster speeds and more features. Students, people with dyslexia or low vision, and busy professionals who listen while doing other tasks make up much of its user base.
