Custom Instructions
State your role, recurring constraints, preferred structure and rules you want applied deliberately across normal chats.
Use four separate controls for standing rules, evolving context, broad tone and fine-grained response style.
State your role, recurring constraints, preferred structure and rules you want applied deliberately across normal chats.
Let useful context develop over time. Review, correct or delete remembered information when your situation changes.
Choose the broad tone ChatGPT uses when speaking with you. Task-specific writing instructions can override it.
Fine-tune warmth, enthusiasm, brevity, headers and lists without changing the underlying capability.
Use Temporary Chat when you do not want a conversation to use or update memory, and avoid storing sensitive information simply for convenience.
The current prompt has the most immediate influence, while standing settings provide context and style around it.
A specific instruction in the current chat can override your normal style for that task. For example, a request for a formal board memo can outweigh a generally casual personality setting.
Memory can maintain a continually updated synthesis of useful context rather than only a static list of facts. Review the Memory Summary because old roles, preferences or projects can become inaccurate.
Turning memory off does not delete earlier chats. To fully remove a detail, you may need to remove every place where it exists, including chats, files, memory and connected apps.
