Are there any AI tools that can completely clear chat history?

Here's a frustration I'm running into: it's great that AI remembers context and follows the thread when you're deep in a topic. But when I want to pivot to something completely different, it keeps circling back—almost too eager to stay "relevant" to what we discussed earlier.

This makes the new conversation feel forced and unhelpful because it won't let go of the old context. I've tried deleting the chat and turning off data collection, but neither worked.

Anyone else stuck in this loop?
Did you find a fix?
