If I got a contractor now that offered it for free there is exactly 0.00006% chance I would take it (job is $40k-ish). nothing is free :)

ChatGPT without a login is basically a 5 minute free trial with no integration with any other system besides web search.

You get bumped down to a way worse experience almost immediately and the login nags are so strong that logged-out use is almost certainly going away in the near future.

It’s like the contractor that comes over for free but mainly does so to find every possible problem in your house that they might be able to charge you for.
