After I posted about https://cosme.dev/ask-docs on Reddit I received some messages asking me how If I was going to make the code open source or if I could show them how I did it.
So I decided to create this repo so you can take a look at the code and maybe apply the same techniques on your own apps. It's made using only PHP as language so I think is pretty different since most stuff out there is made using python or javascript.
It uses the OpenAI API and Redis as a vector database.
