I have not used this website before nor do I know the price but there are multiple like it. For example I particularly like DoorHunter. It costs $25 per month but I think it is worth it, it probably saves me a multiple hours a month looking at and analyzing deals.
In terms of "does it work" all of these websites do the same thing, they aggregate data from multiple sources, pull listings from the MLS, and then automatically calculate cash flow for you. They all work more or less the same, although rents and ARV can always be hit or miss, I would say the differences mainly come from usability.
AI estimates sound great on paper. Questioning them is the way. A real rent CMA on a few actual comps tells you more than any number a tool spits out. What market are you looking at?
