TeXPatch

TeXPatch cleans up common TeX/LaTeX issues in Markdown so KaTeX/MathJax renderings look correct across Obsidian, Quarto, and web docs.

What it does
• Patches common TeX/LaTeX quirks (e.g., |x| → \lvert x\rvert)
• Respects code fences and inline code (won’t touch your code blocks)
• Idempotent transforms (safe to run multiple times)
• Local-only: no permissions, no network calls

How to use
1) Click the TeXPatch icon to open the popup.
2) Paste Markdown containing TeX/LaTeX.
3) Press “Patch,” then “Copy” to use the fixed output.

Privacy
TeXPatch runs entirely in your browser. No data leaves your device.
