Copy LaTeX code from rendered math expressions on web pages.

Users cannot easily copy the underlying LaTeX source code from math rendered by KaTeX or MathJax on websites like ChatGPT, Wikipedia, or Stack Exchange. This extension extracts the raw LaTeX/Typst code.

User installs extension -> Content script injects into all pages -> User hovers over a math expression -> Overlay appears -> User clicks overlay -> LaTeX code is copied to clipboard. Alternatively, user selects text with math and uses context menu to copy as Markdown.

Target users: Students / Researchers / Math enthusiasts / Users of ChatGPT/DeepSeek for math

Analysis is based on static source code. Runtime behavior on specific sites (e.g., if a site blocks the extension) is not tested.

Monetization

No paid features detected

The extension is completely free. The source code contains no references to payment gateways, subscription management, license keys, or feature gating. The keyword 'pro' found in the static analysis (e.g., background.js line 3, turndown.js line 368) refers to JavaScript prototype inheritance or promise resolution, not a paid product tier. The extension is open-source (GitHub repo mentioned in description) and has no monetization logic.

Confidence: 100
Payment platform: --
Source: AI / High
Login required: No
Reason: The extension is a local browser utility that operates entirely within the user's browser context. It uses local storage for preferences (popup.js lines 17-39) and content scripts to detect and copy LaTeX from the current page. There is no code for authentication, session management, or communication with any login-required service. The core workflow (hovering over math to copy LaTeX) works immediately upon installation without any account.
