I think there is a pretty large interest in something like this. But I don't think it will as simple/automated as you would like.

At the minimum, you would need to test/review each product. Provide truly valuable insights, and touch/feel each product side by side.

There are several people that do this in their respective niches, and make a quite a good living for themselves. But keep in mind it took them years of doing it for fun and acquiring taste before anything worked out.

Based on your original post, if I visited the site.It would feel like one of those low quality affiliate link stuff websites.

But if you add some truly valuable insight,data etc. It could be worth it.
