I've talked with an AI about suicidal ideation. More than once. For me it was and is a way to help self-regulate. I've low-key wanted to kill myself since I was 8 years old. For me it's just a part of life. For others it's usually REALLY uncomfortable for them to talk about without wanting to tell me how wrong I am for thinking that way.
Yeah I don't trust it, but at the same time, for me it's better than sitting on those feelings between therapy sessions. To me, these comments read a lot like people who have never experienced ongoing clinical suicidal ideation.
