Personalize ChatGPT so its responses and working style better match your preferences. You control which personalization features are enabled and can change them at any time in the ChatGPT desktop app settings.
Choose a personality
Choose Friendly, Pragmatic, or None as the default personality in Settings > Personalization. A personality changes how ChatGPT communicates; it doesn’t change what the model can do.
Add custom instructions
Use custom instructions for preferences you want ChatGPT to follow across
chats and tasks, such as your preferred response style. In Codex, these personal
instructions are stored in your global AGENTS.md file. Projects and
repositories can also provide their own instructions.
Learn how AGENTS.md instructions work.
Carry context forward with memories
Memories let ChatGPT carry useful context from earlier chats and tasks into future work. They can include stable preferences, recurring workflows, project conventions, and other context you would otherwise need to repeat.
Memories are separate from required project guidance. Keep instructions that
must always apply in AGENTS.md or checked-in project documentation.
Add recent screen context with Chronicle
Chronicle is an opt-in research preview that can augment memories with recent screen context. It’s available to eligible ChatGPT Pro subscribers in the macOS desktop app and requires Screen Recording and Accessibility permissions.
Review Chronicle’s privacy, security, storage, and rate-limit considerations before enabling it. You can pause or disable Chronicle at any time.
Manage personalization
Open Settings to update your personality, custom instructions, memories, and other available personalization controls. See ChatGPT desktop app settings for an overview of everyday preferences.
