Text and Math Reader

Reads web pages aloud sentence by sentence, with highlighting, and reads math formulas in 13 languages.

Text and Math Reader reads web pages aloud, one sentence at a time, and follows along with highlighting so you never lose your place. It also understands math: formulas are read the way a person would say them, instead of being skipped or spelled out symbol by symbol. READING • Finds the article text on a page and reads it sentence by sentence. • Highlights the current sentence and the word being spoken, and scrolls along (you can turn following off). • Hover a sentence to see it highlighted; click it to jump there. • A floating player on the page: play/pause, previous/next sentence, speed, volume, and a progress line. Drag it wherever you like. MATH • Reads formulas from MathJax, KaTeX and MathML pages, e.g. "d x over d t equals f of x comma u". • On MathJax and KaTeX pages, highlights the part of the formula being spoken: the fraction, the limit, the term. • Math can be read in 13 languages: English, French, German, Italian, Swedish, Norwegian (Bokmål and Nynorsk), Afrikaans, Hindi, Korean, Spanish, Catalan and Danish. "Auto" follows your voice's language. VOICES • Uses your browser's and system's voices. • No voices on your system (for example some Linux browsers)? Download a built-in voice once and it works offline: 23 voices in 12 languages, all with training data licensed for public use. PRIVATE BY DESIGN • Everything runs in your browser. No account, no tracking, nothing is sent anywhere. • The only network requests are downloads of built-in voice files you choose, from Hugging Face and jsDelivr. Speed from 0.5× to 3×, volume control, light and dark themes. Free software under the GNU GPL v3 or later.
