CHATGPT MEMORY
What ChatGPT remembers.
Last verified
What does ChatGPT remember?
Two separate things: saved memories, which you create deliberately, and reference chat history, which reads across your past conversations. They are controlled separately.
Does ChatGPT memory work differently in the UK?
OpenAI says ChatGPT's memory features and controls can vary by plan and region, so check the settings in your own account.
Can ChatGPT read an outside memory store?
Yes, through a custom MCP connector, within plan limits. Custom connectors in ChatGPT need developer mode, set up on ChatGPT on the web under Settings, Apps, Advanced settings, Developer mode. Full read and write is a beta on Business, Enterprise and Edu, once an admin turns it on; Pro gets developer mode with read-only access; Plus and Free do not have it.
