This is a Joke!
It’s the kind of product that gives legitimate AI offerings a bad name. Among its most egregious shortcomings are nonsensical ‘solutions’ like “Although <our answer> is not the same length as the one you specified, it is a *probable* solution to the provided clue.” I got these over 50% of the time of the several dozen NY Times clues l tried. For many of these you have to provide so many letters from the crosses that the solution becomes obvious to you. Bottom line: There’s not much ‘intelligence’ going on here - it’s more like a dictionary search, or built upon the much more useful Onelook.com web site. PS Although nominally ‘free’, you almost immediately have to sit through 15 second ads to continue unless you pay $4.99 or more.
