intrepidlemon / Snap2LaTeX

A minimalist macOS app to convert a snap of Equation to LaTeX without paying :shrug:

Snap2LaTeX

Snap2LaTeX is a tool that converts a picture of a mathematical equation into a LaTeX code. It uses https://github.com/NormXU/nougat-latex-ocr to recognize the equation and convert it into LaTeX code.

Compared to LaTeX-OCR, Snap2LaTeX is a standalone application that does not require any install. It has a simpler interface and uses MPS by default.

Usage

Download from releases.

Run the application.

The application will start downloading the model. It will take a few minutes.

There will be an icon in the system tray.

Click on it and select "Capture" to capture a screenshot of the equation. The application will then recognize the equation and display the LaTeX code. When the processing is in progress, the icon will turn yellow.
