@emarketniga Here I'll give you the read frontend and backend codes, just edit the backend code where you need to add your own working API key instead of YOUR_OWN_API_KEY i put it, and substitute the 2 links in the javascript with your own website URL, by copying your main website link from the search bar and paste it in the first 2 variables of the backend code where i wrote YOUR_WEBSITE_URL.

@husein can i do gemini api instaed of openai how i do it

@moh6 Yes you can, you'll need to add your gemini API key instead of the openai one, and change the code that calls for openai's llm with a code that code that calls for gemini's llm.

@husein can you give me the code I traid some but didn't work

@moh6 Can you attach the code you tried so that I can see what's the problem?

@moh6 Please dont attach your code like this, when you wonna attach codes use the "Attach files" button in the editor. 

Anwyways, I edited the code just enter your API key and it should work.

@husein i sorry  i didn't mean that but thanks for your help
