2 | GPT Index Extension for Google Chrome

4 | To use:
5 | 1. Download this repo as a ZIP file from GitHub.
6 | 2. Unzip the file and you should have a folder named gpt-index-extension.

11 | This extension asks for your OpenAI API key to use during webpage indexing and querying. Specifically it's only passed into the LangChain function call and never stored server side. You can also leave the API field blank and it will use mine, but please don't abuse or I will remove that feature.
