A python script that convert the mathematics LaTeX format that you can copy from ChatGPT, into the LaTeX format that markdown (such as Obsidian) can display.

gpt2md.py

"""
This script automatically converts the output of GPT-3 to markdown format.

Future: convert this script to be a chrome extension.


For linux users, they might need to install `xclip` or `xsel` to find clipboard mechanism.

`sudo apt-get install xclip`: Install xclip

Thanks! I modified this to replace the pyperclip dependency with xclip.

Tip for dmenu/rofi/etc. users: copy this script as gpt2md in a directory that's in your PATH (like /usr/local/bin/gpt2md) and make it executable with chmod +x gpt2md. make sure #!/usr/bin/env python3 is at the top of the file.

@sw1jari Nice to meet you. Thank you for trying out my script.
It seems you have made the script more compatible in Linux environmnet. Good work!
