Lesson 3 of 8
Memory
6 min read
You open a brand-new chat, and it already greets you by name and remembers you're learning Spanish. You never said so in this chat. How does it know?
It remembers across chats
Normally each chat is a blank page — close it and it forgets. Memory changes that. When something looks worth keeping ("I'm vegetarian", "I write in British English"), ChatGPT saves it to a store that sits outside any single chat. Open a fresh one, and those saved facts quietly come along.
A single chat's memory ends when the chat does. Memory is a separate store that carries facts between chats.
You're in control
Memory isn't a black box. You can see everything it has saved, delete any single fact, turn it off entirely, or open a temporary chat that saves nothing. Treat it like a notebook ChatGPT keeps about you — one you're allowed to read and edit.
Convenience has a cost: what it remembers, it can also surface later. Check the saved list now and then, and clear anything you'd rather it forgot.
Memory can save more than you expect from an offhand comment. If you're sharing something sensitive, use a temporary chat — or check the memory list afterwards and delete it.
The shape of it
- —Memory stores facts outside any one chat, so they carry to new ones.
- —You can view, delete, or turn off what it saves.
- —Temporary chats let you talk with nothing saved.
In a fresh chat, ChatGPT greets you by name and knows you're vegetarian — though you never said so here. Why?
