how AI would enhance web browsing

I'm not a fan of calling these LLM things "AI", but there are tons of things where this could make sense to help in decision-making. Example scenarios:

• I want to plan a vacation but I don't have a exact plan or date. Instead of aimless browsing around or giving my data to a bunch of travel sites that will bombard me with "deals", I can set up an "AI agent" that will check the current prices, weather conditions and etc to find spontaneous trips.
• I want to make a "DIY" project and some of the components are fixed by the design, but others can vary. An AI can give me suggestions for variations and find me the best prices for the materials required.
• If I am looking at a product on Amazon, an AI can summarize the reviews in a way that I care about.
• I can find a recipe that a like and ask an AI to make a vegan/gluten-free/kosher version of it

etc, etc, etc...
