One note for those still using the Claude system for chats: there's no system to get generated images, spreadsheets, etc. out of the system. They claim it's a "security concern" to provide that data to you, as if they are protecting you by refusing to follow data export laws.

I'm hesitant to email their data emails, as it's common for companies to delete all data upon any request, instead of providing data as they are required to.
