I am not sure how well the tag system will work.
I did test the Kagi Assistant for 2 weeks, and decided its not near wehre my experience with ChatGPT Projects is.
I love that it uses kagi search, but I do use ChatGPT projects a lot, and I just update the files it keeps in context...
but what it tells me now is:
Files impacting responses
Responses may be lower quality due to the number of files this project is using.
With the tags just adding and adding, I am not sure if that would't defeat the purpose in the long run.
So in the end I am not sure if that will actually result in the desired state.
