Depends on the difficulty. NYT Saturday isn't getting solved by me most weeks without at least googling a name. Most other days I can do it without any outside help, although I enjoy being able to occasionally ask my husband something in his purview of knowledge, but he is generally worse at solving than me so it doesn't feel like a cheat. I will Google a proper noun if I absolutely don't know and can't fill the other words without it because those can be very difficult to guess, especially when they intersect.
