Accessible STEM course materials
Equations that read aloud correctly.
We convert textbooks, problem sets and lab manuals so screen readers speak every equation the way it is written, every graph has a description, and every table reads in order.

Spoken by a screen reader
“x equals the fraction: negative b plus or minus the square root of b squared minus 4 a c, over 2 a.”
The quadratic formula, written in MathML. Exact speech depends on the screen reader.
1.1Why math needs its own treatment
Real math markup
MathML, not pictures
An equation saved as an image is silent to a screen reader. We rebuild it as MathML, so it can be spoken, navigated and enlarged.
Graphs and figures
Descriptions that teach
Alternative text that says what a graph shows, not just that a graph is there.
