Blabby is a text-to-speech app designed to be a joy to use. What you type is read out loud in real time, word by word, so your conversation partners don’t have to wait for you to type the entire sentence. And there’s no need to type the same things over and over! Commonly used phrases can be saved as Quick Presets for one-tap access, or to the Bookmarks. Sometimes text is the most effective way to communicate. Blabby displays your sentences in huge letters, so you can just show someone your screen, even at a distance. Polyglots can easily enable multiple languages and quickly switch between them. English (UK and US), French, German, Italian, Japanese, Korean, and Spanish are supported. If your language isn’t supported, please email feedback@kaylees.site and let me know. And obviously: no ads, no tracking, no data collection, no account required, no dark patterns. Blabby was built with love and patience. I hope you’ll enjoy using it as much as I enjoyed making it!
