Memory Management

ChatGPT Plus Memory stores dynamic notes about you across sessions. Instructions for adding, removing, and maintaining memory to keep it accurate and useful.

Syntax

chatgpt
# Add a memory:
"Remember that [fact/preference]"

# Remove a memory:
"Forget that [old fact]. [Reason]"

# View and manage:
Settings → Personalization → Manage Memories

# Memory vs Custom Instructions:
Custom Instructions → stable, universal
  (role, stack, communication style)
Memory → dynamic, project-specific
  (current projects, recent decisions)

Example

chatgpt
# Good Memory entries:
"Remember I prefer Vitest over Jest for new projects"
"Remember my team follows Conventional Commits"
"Remember I'm building a patient portal — Supabase auth,
 Vercel hosting, HIPAA-adjacent data handling"

# Stale entries to delete:
- Old project names that completed
- Deprecated tech preferences
- One-off decisions no longer relevant

# Pruning:
"Show memories about [old project] and delete them
— that project is complete."
