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. Open source Questions or feature requests?
