I was using ChatGPT regularly for work and personal tasks when I saw the “memory full” message. I couldn’t save new preferences or project details, so I reviewed old memories, deleted unnecessary ones, and cleared space to store important information again.

If ChatGPT shows “memory full”, it means it has reached the limit of stored remembered information about you. To fix or manage it:
What you can do:
Delete old memories
Go to: Settings → Personalization → Memory → Manage Memories
Remove things you no longer need ChatGPT to remember
Clear specific items
Instead of clearing everything, you can delete individual memories one by one
Turn off Memory (optional)
If you don’t want ChatGPT to store anything, you can disable Memory completely in the same settings
Continue chatting normally
Even if memory is full, ChatGPT still works fine, it just won’t store new long-term info until space is freed
Tip:
It’s a good idea to periodically review memories so only useful and relevant ones are kept.
