Settings

Fluent settings are organized into tabs that cover everything from basic preferences to advanced customization.

Access settings from the menu bar or with the keyboard shortcut.

General

The General tab contains the most common settings.

Language Settings:

Choose your native language. Fluent uses this to improve responses and UI elements when appropriate.

Global AI Model Selection:

Set the default model for all conversations. This is the model Fluent uses unless you manually select a different one in the Smart Panel.

You can override this default on a per-conversation basis or when running specific actions.

Appearance:

Choose between System, Light, or Dark theme:

• System follows macOS appearance settings
• Light always uses light mode
• Dark always uses dark mode

System Settings:

• Launch at login – Start Fluent automatically when you log in to macOS
• Keep dock icon on – Show Fluent in the Dock (disable for a cleaner Dock)
• Hide menu bar icon – Hide the menu bar icon if you prefer keyboard-only access

Advanced

The Advanced tab contains settings that change Fluent behavior and are intended for users who want more control.

Warning: These settings can change Fluent behavior, proceed at your own risk.

System Prompt:

The system prompt defines how Fluent behaves across all conversations. Click Customize to modify the default instructions that guide the AI's responses.

The default system prompt is carefully designed. Only customize it if you have specific requirements and understand how system prompts work.

MCP Prompt:

The MCP prompt controls how Fluent uses Model Context Protocol tools. Click Customize to modify the instructions that guide tool selection and usage.

This is separate from the system prompt and focuses specifically on MCP behavior, such as:

• When to use MCP tools
• How to select the right server
• How to chain tool executions

Experimental Features:

• Expressive responses – Enable AI model to respond more expressively, using formatted layouts (e.g., lists, tables, etc.)
• Include emojis – When enabled, the model may include emojis in responses
• No em dashes in response – Instruct AI to avoid em dashes unless provided or explicitly requested

These features are experimental and may change or be removed in future versions.

PopClip:

Install a PopClip extension that opens Fluent or its actions with the selected text. This is useful if you use PopClip for text editing workflows.

Click Install to add the extension to PopClip.

Other Settings Tabs

In addition to General and Advanced, Fluent has dedicated tabs for:

• Smart Panel – Position mode, shortcuts, and panel behavior
• Models – Provider API keys, model selection, and custom providers
• Context – App and browser context settings
• Integrations – MCP integrations and tool management
• Memory – Memory groups and knowledge management
• Variables – Custom variables and built-in variable configuration
• History – Retention, cleanup, export, and import
• Blacklist – Apps where Fluent should not activate

Each tab focuses on a specific Fluent feature and contains all related settings in one place.

Restore Defaults

Most customizable settings include a Restore to built-in option that resets them to the original default.

Use this if you've made changes and want to go back to the standard behavior.
