New to PH. Where should I go to find the most value to take and to offer? ( Launching here soon! )

I have this chrome extension I'm building that uses AI to make online-self learning more engaging. Creates questions about what you are learning in something like Wikipedia and checks in every minute or 2 with a question about what you are learning to see if you are "actually" learning or just scrolling. Comes with note taking, mind mapping, whiteboarding, an AI co-pilot - all of it. I think PH would be a good place to launch this and I just joined yesterday. I do see a lot of great products being showcased here but since I'm new, I am not sure what I should be doing first and where I can add the most value and where I can learn how to improve my launch.
