Long-Term Memory Patterns: Profiles, Preferences, and Facts

What belongs in long-term memory

  • User profile basics (name, role, product plan)
  • Preferences (tone, format, units)
  • Stable facts (project name, recurring context)

What should NOT be stored

  • Passwords, OTPs, private identifiers
  • One-time transactional data (unless required)
  • Anything user didn’t consent to

Schema matters

Store memory in typed fields, not one blob. Example structure:

  • preferences.format = “HTML”
  • preferences.language = “en”
  • work.project = “Edugators Courses”

Typed memory is easier to validate, update, and delete.

Keeping memory truthful

Long-term memory can become outdated. Use:

  • timestamps
  • confidence scores
  • user-confirmation prompts when uncertain
