Step-by-Step Instructions

Launch Cursor IDE

Open Cursor from your desktop or applications folder. Wait for the editor to fully load with your workspace or create a new project if needed.

Make sure you're signed in to your Cursor account for full AI features

Locate the AI Chat Icon

Look for the chat bubble icon in the left sidebar panel. It's typically located below the file explorer and above the extensions icon. The icon resembles a speech bubble or message icon.

If you don't see the icon, try resetting your layout from the View menu

Click the Chat Icon

Single-click on the chat icon to open the AI sidebar panel. The sidebar will expand to show the chat interface with a text input field at the bottom.

Use Keyboard Shortcut (Alternative)

Press Ctrl+L on Windows/Linux or Cmd+L on Mac to quickly toggle the AI chat sidebar open and closed. This shortcut works from anywhere in the editor.

The keyboard shortcut is faster once you get used to it

Verify Chat Interface

Confirm the chat sidebar is active by checking for the text input box at the bottom labeled something like "Ask Cursor" or "Chat with AI". You should also see any previous conversation history above.

The sidebar should show your current model selection at the top

Start Your First Chat

Type your question or request in the input field and press Enter or click the send button. The AI will respond in the chat area above your input.

Try asking about your current code by referencing specific functions or files

Adjust Sidebar Width

Drag the vertical border between the sidebar and main editor to resize the chat panel. Make it wider for better readability of longer AI responses.

A wider sidebar makes it easier to read code suggestions and explanations
