You then write GREP formulas in your Paragraph Styles to automatically apply those character styles whenever InDesign detects specific patterns (e.g., finding any digit that comes immediately after a caret ^ symbol and making it a superscript).

Export the equations as individual or EPS files. Because these are vector formats, they can be scaled infinitely inside InDesign without losing sharpness.

: Offers a WYSIWYG interface for K-12 and post-secondary math.

Use MathPix to digitize images into vector math.

In InDesign, use File > Place to import the vector graphic.

LaTeX is the gold standard for math. You can convert LaTeX into a vector graphic (EPS or SVG) for free.

By combining these free tools, you can produce publication-quality mathematical content in InDesign without spending a dime on a plugin.

You cannot find this on Adobe Exchange (which mostly hosts paid plugins). Instead, head to:

Here is a deep dive into the best free ways to handle math in InDesign. The Reality Check: Plugins vs. Scripts

This script processes MathML objects in InDesign documents, creating knockout effects with user-selected colors for both math expressions and backgrounds. It eliminates limitations restricting MathML objects to RGB color space only, supporting CMYK/Spot Color treatment and output for MathML objects directly from InDesign. This tool is best for print professionals requiring color-accurate mathematical content in commercial printing workflows.
