Is it safe to paste confidential contracts into ChatGPT?

Not on the default consumer tier: prompts can feed training, chats are retained for abuse monitoring even after deletion, and a US federal court has already held AI conversations carry no privilege.

Assume anything you paste could one day be read back to you in discovery, and treat NDA-covered documents accordingly.

A quick orientation. The real value is below: resources worth your time, from people who've actually done it.
