Memory is a short list of standing preferences and facts about you that Chat keeps on your account and reads into every conversation. It is how Cortex remembers that you prefer British spelling, work in euros, or want answers to start with the conclusion — without you repeating it.
Memory, two-factor authentication, and Your data controls under Settings → Data & privacy

Settings → Data & privacy → Memory. Every saved memory is listed and can be deleted on its own.

What memory is

​
How memories are created

Chat saves a memory when you tell it something worth keeping — always answer in French, my team ships on Thursdays — or when it recognises a standing preference from how you work. Memories are read at the start of a turn alongside project instructions.

​
Review and forget

1

Open Settings → Data & privacy

Each entry is a short sentence in plain language.
