When using the AI Assistant within Foxit PDF Editor, you can manage your chat history from the menu that appears after clicking the Information 
icon at the top of the AI Chat panel:
Clear History: Remove all previous interactions linked to the currently open document, or all interactions not linked to any document (i.e., your entire chat history when no document is open).
Clear All History: Remove all previous interactions across the application, whether associated with documents or not.
Temporary Chat: Enable a temporary chat session. Temporary chats are not saved in history, used for memory recall, or included in AI model training.
