# Settings Overview

> Configure Qualia's behavior, appearance, and integrations.

Settings let you customize Qualia to match your workflow. Open Settings by clicking the **gear icon** in the bottom-left corner of the sidebar.

## Settings organization

Settings are organized into tabs on the left side:

## Quick search

Use the search box at the top of Settings to find specific options. Search matches setting names, descriptions, and keywords.

## Saving changes

Most settings save automatically as you change them. Some (like API keys) require clicking a save button.

## Settings scope

Settings are global — they apply to all workspaces. For project-specific behavior, use:

* [Rules](/rules) with workspace files (CLAUDE.md, AGENTS.md)
* [Skills](/skills) stored in your project
* Per-session overrides in the chat interface

## Default values

Settings have sensible defaults out of the box. You can reset individual settings or use the [Data Management](/settings/data-management) tab to reset everything.
