Desktop Layout

The AgentOne desktop app has three main areas: the sidebar, the main chat area, and the composer. Understanding where everything lives makes navigating the app much faster.

Sidebar

The sidebar runs along the left side of the app. It is your navigation hub for everything chat-related.

From the sidebar you can:

• Click New Chat (or press Ctrl+N) to start a fresh conversation.
• Browse your recent chat history, organized by recency.
• Search chats by title or message content with the search button or Ctrl+K.
• Open the Settings panel from the bottom of the sidebar.

Each chat row shows its title and, when applicable, a status indicator or branch icon. Right-clicking a chat (or clicking its ... menu) gives you actions like rename, export, and delete.

For full details on working with the sidebar and managing chats, see Chat Sidebar.

Collapsing the Sidebar

Press Ctrl+B to collapse the sidebar. When collapsed, a small set of icon buttons stays visible so you can still create new chats and search without opening the sidebar. You can choose whether these buttons appear in a row or column in Settings -> Appearance -> Collapsed Sidebar Layout.

On narrower windows, the sidebar becomes a drawer that slides in when needed rather than staying pinned.

Main Chat Area

The center of the app is where your conversation lives. It shows:

• The full message history for the current chat, scrollable from top to bottom.
• Streaming responses as the model generates them, with a stop button to interrupt.
• Tool activity - when an extension runs during a response, its actions appear inline as collapsible items so you can see exactly what the model did.
• Message action rows - hover over a message (or always show them, depending on your settings) to access copy, edit, branch, and regenerate actions. See Message Actions.

Composer

The composer sits at the bottom of the chat area. It is where you type messages and configure the current chat. It contains:

• Message input - type your message here. The placeholder says Ask anything.... Press your configured submit key (Enter or Ctrl+Enter) to send.
• Attachment button - click the paperclip icon to attach files, or drag files directly into the composer. See Attachments.
• Model selector - the pill-shaped button showing the current provider and model name. Click it to switch models. See Model Selector.
• Model config button - next to the model selector. Click it to adjust temperature, max tokens, and other per-chat parameters. See Model Config.
• Send / Stop button - sends your message when idle; turns into a stop button during generation.

Settings

Clicking Settings in the sidebar opens the settings view. It is organized into sections:

See Settings for the full breakdown of each section.

Keyboard Shortcuts

You can navigate the entire app without touching the mouse. See Keyboard Shortcuts for the full list.
