L3 Guidelines
- Not a psychological counseling or medical service; in case of a crisis, please seek help from real people or emergency hotlines (see Chat Safety Guidelines).
- L3 will enhance content safety reviews; inappropriate topics will be gently refused.
- Once the L3 protocol is disabled or the account is canceled, the L3 option will no longer be available.
Chat Memory

- This summary will not be written into "My Space" tasks/documents.
- View and delete: Chat memory and YOYO's understanding of me
- Long-term preferences (My memory) and notes are different capabilities; see the comparison table on that page.
