Hello,
it's ok
The AI is inside ClicShopping, you do not need to install APP anything
Just activate the module and insert the key you can found on OpenAI.com. In function of the situation, you must activate some modules for the catalog.
For the instructions, you have a tuto there : ttps://www.clicshopping.org/forum/topic/3387-how-to-use-the-generative-artificial-intelligence-inside-clicshopping/
For the terminal, you must go on admin hosting. Else ask the support to help you.
