The KaTeX to MathJax plugin streamlines the integration of mathematical expressions into Obsidian by converting KaTeX notation to MathJax format. This is particularly useful for users who copy mathematical content from platforms like ChatGPT, which often use KaTeX. The plugin features automatic conversion upon pasting, ensuring that your notes maintain proper formatting without extra effort. Additionally, users can manually convert text within individual notes or across the entire vault using the command palette. This functionality enhances the usability of mathematical expressions in your notes, making it easier to work with complex equations and maintain a polished appearance in your documents.
