My fast mode search was without login. For deep, I logged in and provide more context during chat. Will try fast mode with more details added to the profile.
Tried it for a birthday party setup and got a reasonable list of things I hadn't thought about. Saved me the usual back-and-forth between Pinterest, Google & Amazon.The tier breakdown is actually useful, most of the time I just want the middle option and it's right there.
The Deep mode worked better for me. it asked follow up questions before building the cart and the results were more personalized than quick mode.
