I came across this website courtesy Google search, used their services successfully; and today I find out it's on product hunt! If you are 'driven' by the need to discover what font 'that person/ company' uses, then this should be your go-to solution site. For most of us it would be a once in a blue moon need, except for the professionals, but then, they might be already conversant with most fonts?! It's a nice service that I used gratis. Since I was much too engrossed in the work of getting the image just right for the system's AI recognition to work, I didn't notice any ads, so I wonder what the business model is, when most users would be on one-off missions like moi. Nevertheless, a praiseworthy effort that does live up to it's promises.
I use it when i get some artwork to modify from clients but there is no source. The old designer left and all the client has is the final product not the vectors or sources. Good product, saves me a lot of (unbillable) time
