AI moderated Chat system for Mental health Support groups.

When I was recently having a chat conversation about a mental health issue a friend was going through, We spoke about different topics and shared our own experiences. During that time I got an idea, which is an AI moderated chat system, where people can conversate naturally about their problems. The AI will intervene on request to help in different ways, like warning - if someone is suggesting potentially harmful soliution, cautious signal when someone shares misleading information that isn't scientifically correct, similar moderations and also providing existing documented knowledge that is relevant to the topic of discussion, so that the users will get to learn about their issues more properly throug evidence.

I imagine this to be a advanced system of existing chatbots, but only difference is its not human- AI interaction, but rather, keeping the human-human interaction as centre focus and just enabling people to support each other better with AI intervention when/ if needed. This could be a plug-in tech that can be integrated into small friends/ family groups to large support groups, where Human moderators cannot intervene regularly.
