# Personalize ZeroTwo

Personalize ZeroTwo 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 ZeroTwo desktop app settings.

## Choose a personality

Choose **Friendly**, **Pragmatic**, or **None** as the default personality in
**Settings > Personalization**. A personality changes how ZeroTwo communicates;
it doesn't change what the model can do.

## Add custom instructions

Use custom instructions for preferences you want ZeroTwo to follow across
chats, such as your preferred response style. In ZeroCode, 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](/agent-configuration/agents-md).

## Carry context forward with memories

[Memories](/customization/memories) let ZeroTwo carry useful context from earlier chats
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](/customization/chronicle) is an opt-in research preview that can
augment memories with recent screen context. It's available to eligible
ZeroTwo 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**](zerocode://settings) to update your personality, custom
instructions, memories, and other available personalization controls. See
[ZeroTwo desktop app settings](/reference/settings) for an overview of
everyday preferences.
