Word supports linear equation input, but OMML is the native equation format. Learn when Alt+= is enough and when you should convert LaTeX to OMML.

Quick tip Convert LaTeX (or AI-generated math) into native, editable Word equations (OMML).

Quick answer

If your AI output includes LaTeX (like \frac{a}{b}) and you paste it into Word, it usually becomes plain text or breaks. Use native Word equations (OMML) instead. The fastest workflow is: save the AI output in a .docx or .txt, convert it, then download a Word file with editable equations.

What is OMML (in one paragraph)

OMML (Office Math Markup Language) is the XML-based format Word uses to represent equations as native objects. That’s why OMML equations are editable and render consistently in Word.

When Alt+= is enough

Alt+= is perfect for a few equations you can type manually. For a full assignment, long derivations, matrices, or dozens of equations, conversion is faster and less error-prone.

A practical rule of thumb

  • 1–3 short equations: use Alt+=.
  • Anything longer: convert LaTeX → OMML to keep everything consistent.

Recommended workflow (step-by-step)

  1. Ask your AI (ChatGPT/Gemini/Copilot/Claude/Perplexity) to format math as LaTeX using $...$ for inline and \[...\] for display.
  2. Copy the result into a .docx or .txt.
  3. Upload it to the converter and download the converted .docx with native Word equations (OMML).
  4. In Word, click an equation to edit it and confirm it behaves like a real Word equation.

FAQ

Will my equations remain editable?

Yes—OMML equations are editable inside Word’s equation editor (they are not images).

Do you store my files?

No. The converter processes the upload to generate the output and does not keep files long-term.

Does it work with matrices and cases?

Most common LaTeX math is supported, including fractions, roots, matrices, and aligned equations.
