NotebookLM is a powerful tool for organizing and reasoning about technical content, yet its lack of native LaTeX rendering limits its usefulness for math-heavy workflows. This project bridges that gap, making NotebookLM a more practical workspace for students, researchers, and engineers who frequently work with equations and symbolic expressions.
About This Update
This project builds on an existing NotebookLM LaTeX renderer. I contributed targeted improvements to make the renderer more reliable:
-
Previously, math split across multiple DOM nodes (e.g., with
\forallor set-builder notation) was parsed in fragments, causing partial or failed renders. I fixed this by coalescing all contiguous text between math delimiters into a single string before rendering. -
Additionally, in the original version,
%inside math was treated as a comment start by KaTeX, truncating content. The fix here was to escape percent signs as\%inside math prior to parsing. -
Previously, expressions spanning table cells or
<br>seams were skipped because detection stopped at structural boundaries. To fix this, I normalize and flatten content across table and<br>boundaries so full expressions are detected and rendered.
Features
- Supports both inline (
$...$) and display ($$...$$) math - Lightweight, client-side transformation (no backend dependencies)
- Safe HTML parsing and escaping to prevent injection vulnerabilities
- Works seamlessly in existing notes—no migration required
- Configurable math delimiters for custom syntax
- Simple installation via userscript or browser extension
- Fully open source on GitHub
Example Usage
Before
After
Inline: $e^{i\pi} + 1 = 0$
Block:
$$
\int_{-\infty}^{\infty} e^{-x^2} \; dx = \sqrt{\pi}
$$
