Why it happens
AI tools often output math in LaTeX, but Word stores editable equations as OMML. When you paste raw LaTeX as text/HTML, Word may mis-handle characters and fonts, producing question marks or odd glyphs.
Fix A (recommended): convert the full document to native Word equations (OMML)
For many formulas (a long AI answer, homework set, thesis excerpt):
- Save the AI output (with LaTeX) into a .docx or .txt.
- Upload it to the LaTeX → Word converter.
- Download the DOCX with editable native equations (OMML).
Fix B: only 1–3 equations? Use Alt+=
In Word: Alt + = opens the equation editor. Paste/type inside it and convert to Professional form.

Root causes
- Font issues: the chosen font lacks a math glyph; use Cambria Math or a compatible math font.
- Not an equation object: LaTeX is treated as text, so Word cannot render it correctly.
- Hidden characters: copy/paste may introduce invisible characters that break parsing.
Tip: For a complete workflow, see the LaTeX → OMML guide.
Fixes that work
- Re-paste as plain text.
- Switch the equation font to Cambria Math.
- Convert LaTeX to native OMML equations using the converter.
FAQ
Why does it work on one computer but not another?
Different fonts and Word versions can change rendering. Native OMML reduces variability.
