I like the product concept over all. Not sure whether there was a need to actually register though, as I could use Platoria straight out of the gate from the landing page. Also, I faaced an issue on sign up - couldn't complete the process as the checkbox to accept the T&Cs couldn't be clicked.
To test, I tried typing in a board game "The Witcher - Old World" (gift I plan to get a nephew), didn't get the result from the landing page. Only found what I was looking for after clicking on "Add Any Product Yourself" - perhaps would help to add a "Didn't find what you were looking for? Click here and we'll look it up for you!" (or something like that :))
The results page for what the board game I searched was clean & easy to understand. Displayed were the product image (carousel form which is great), and the reviews (using the 5 star rating model) and prices across different platforms (Esty, Walmart, Amazon, etc.) - option to see more vendors is great! I clicked on the AI generated summarized review, took more than 3 minutes to load in, but I do like the pros and cons lay-out. Simple to read and make one's own evaluations.
Might also want to refine the "Similar Products" section at the bottom of the page, as what is shown for me are fiction books - other board game alternatives would have been more relevant.
Great job overall Platoria team. Will be using this tool, and looking forward to updates :)
