A math equation editor for teachers that sits next to your document — as a web app here and as an extension for Microsoft Edge and Firefox.

Free, no account, no watermark, no limit: type math like on a calculator (/ makes a fraction, ^ a power, sqrt a root) or paste LaTeX, use 19 symbol buttons or the on-screen keyboard, and put the equation into Google Docs or Slides at your cursor as a sharp image. Every image gets alt text for screen readers, written for you in English, German, Spanish, Portuguese or Japanese — Google Docs keeps it, also in the Word download. Copy as image, LaTeX or MathML, download PNG or SVG, any size and colour, the last 20 equations and 34 ready formulas in 6 subjects.

Premium ($4.99 per month or $39 per year per teacher): math into Google Forms as real text in question titles, answer choices and short answers (x² + ¾x − 1 = 0 — readable by screen readers, nothing to upload), handwriting → math, photo or screenshot → math, voice → math in 5 languages (300 reads a month), and class sets that keep each unit’s equations for every week’s quiz. Without a key, 3 Premium actions a day stay free.

Typing, rendering, alt text and inserting run on your computer. Only a drawing, photo or recording you choose to turn into math is sent to our reader, and it is not stored. Interface in English, Deutsch, Español, Português and 日本語.
