I would like to suggest a feature to improve the chat experience: a smart alert system that notifies users when they significantly change the chat topic. This would help maintain conversation focus and allow users to use the chat as an organized reference. The system could: identify the main topic at the start, monitor new messages for major deviations, and send an automatic warning, e.g.:
> 
It seems your new topic is different from the current one. Do you want to continue here or start a new chat?
Users could then choose to continue in the same chat or start a new one. This feature would keep conversations focused, prevent topic mixing, and make referencing past chats easier for all users .
