A Google Chrome extension designed to preserve mathematical equations (KaTeX/MathML) when copying text from NotebookLM and other configured AI chatbot sites.
- Preserves Math Formatting: Converts KaTeX blocks into properly formatted MathML so equations paste correctly into Microsoft Word, Notion, and other rich-text editors.
- Dynamic Domain Support: Works on
notebooklm.google.comby default. You can easily add other domains (like ChatGPT or Claude) via the settings popup. - Clean Settings UI: Simple toggle to enable/disable the interceptor, and a sleek interface to manage your active domains.

- Click the extension icon in your toolbar to open settings.
- Toggle the interceptor ON/OFF as needed.
- Add any additional domains where you want to preserve math formatting.
