Review your AI agent's long-term memory monthly, delete stale facts, date the ones you keep, and stop task details from leaking into new work.
Who it is for
Anyone whose AI assistant or agent keeps using an old price, an old rule or details from a past job.
Tools
Your assistant's memory settings
A short list of current facts: prices, policies, contacts
A monthly reminder
Steps
Open the memory list. In ChatGPT it is Settings, then Personalization, then Manage memories; other tools have a similar page or a memory file.
Copy the list into the prompt below and get it sorted into keep, update and delete.
Delete stale entries. OpenAI says deleting a saved memory stops it being used, but does not remove it from past chats, so delete or archive old chats that repeat the stale fact.
Rewrite facts that changed with a date, for example: 'As of Nov 2026, call-out fee is $95.'
Keep one-off task details, such as a client's job notes, in that task's project or file, not in memory.
Start a fresh chat after the cleanup, and repeat monthly.
The prompt
Here is my AI assistant's memory list and my current facts. Use only what I paste.
Memory list: [PASTE]
Current facts (prices, policies, contacts, preferences): [PASTE]
Sort every memory into:
- KEEP: still true
- UPDATE: changed; write the new version with today's date
- DELETE: outdated, a one-off task detail, or a duplicate
Give a one-line reason for each. Flag any memory that contradicts my current facts.
Tips
Dated facts make stale ones obvious next month.
Memory is for lasting preferences and facts, not job details.
If something keeps coming back, check old chats and files that repeat it.
