I would say my knowledge on them is relatively minimal. I've only familiarized myself with the common Chatgtp and used Notion to organize some university semesters I had. Recently dived into Knowt and I'm still testing it so far.

Ai has been a constant growing tool, with usually many negative views. I myself debate on it being a relatively useful tool as any development offers. Of course it always has room for improvement which is why I'm curious to see where this group os heading.

When it comes to testing a product it depends on what the intended usage of it is. If it's more of a digital product like a website it higly depends if the main page is understandable to navigate. Making sure all the buttons work and send you to where it needs to. If it were a physical product then again, it all depends on its intended use. If it were a more gentle product used for hygine as an example, it would be more suitable to focus on how long it lasts before you need a new one. If its a product more keen on heavy usage, like training equipment, then its more efficient to test the durability of the product for safe usage.
