How can I get Claude to pull together everything it has previously taught me or discussed on a specific topic across multiple chats?

You can ask Claude to pull up all chats related to a specific topic and summarize what's been covered — for example, asking it to review all chats where you've taught about 7216 and summarize what you've actually taught. This is useful as a starting point since, even though Claude has memory features, its recall across separate chats isn't always complete or reliable.
