PDF+MathJax is a PDF viewer for Chrome that offers the unique ability to render LaTeX in text annotations. With this add-on, users can easily add text annotations by pressing the designated button and have them instantly rendered as LaTeX when exiting the editor. The text box can be moved by dragging it, and users can also cut and paste the text box to other pages of the document.

For those who prefer a more traditional PDF viewer experience, PDF+MathJax can still be used without utilizing the editor. Users can add text annotations through other software and the viewer will render the LaTeX contained within the annotation.

One of the standout features of PDF+MathJax is that the LaTeX is saved as a string rather than an image. This means that it can be easily edited even after saving and reopening the document. Additionally, the program includes PDF.js versionce8716743] and MathJax versionbeta.3, making it capable of functioning offline without the need for remote hosted code.

Keyboard shortcuts are also available for convenient navigation. Pressing Ctrl+O allows users to open a file, while Ctrl+S enables them to save the file.
