STEM Keys

Type math and science symbols with four customizable floating windows, plus numbers, powers, subscripts, and fractions.

STEM Keys puts math and science symbols in floating panels while you work in Chrome. Browse symbols for STEM work. Build up to four custom symbol windows by dragging in the symbols you use most, then name and position each window to suit your work. Features include: • Four customizable floating symbol windows. • Number entry, powers, subscripts, and a fraction builder. • Light, dark, and high-contrast themes. • Tools for students, teachers, and anyone writing math or science. Click into a supported text field on a webpage, then choose a symbol to insert it. Compatibility depends on the website and its editor.
