Chat

The chat page is the primary way to interact with your AI assistant. Open it from the Chat tab in the Coral dashboard.

​
Sending messages

Type your message in the text box at the bottom and press Enter to send. Use Shift+Enter to insert a newline without sending. Your assistant’s response streams in real-time — you’ll see text appear as it’s generated.

​
Attaching images

You can send images alongside your message for the assistant to analyze. Supported formats: JPEG, PNG, GIF, and WebP. Three ways to attach:
  1. Paperclip icon — Click the attachment button in the input area to open the file picker.
  2. Drag and drop — Drag image files onto the input area. A “Drop files here” overlay appears.
  3. Clipboard paste — Copy an image and press Cmd+V (Mac) or Ctrl+V (Windows/Linux).
Attached images appear as thumbnail chips above the input. Click the X on any chip to remove it before sending.

​
Thinking indicator

When you send a message, a pulsing brain icon with “Thinking…” appears while your assistant processes your request. This indicator disappears automatically once the response starts streaming.

​
Tool calls

Your assistant can invoke tools during a conversation — web search, code execution, file operations, and more. When it does, you’ll see inline tool call cards in the response:
  • Spinner icon — Tool call in progress
  • Checkmark icon — Tool call completed
Click any tool call card to open a detail modal showing the full input and output. The modal includes a Source / Rendered toggle to switch between the raw JSON and a formatted view.

​
Quick start prompts

When the chat is empty, four suggested prompt buttons appear below the greeting. These correspond to the pre-built Use Cases and give you a one-click way to start a guided workflow. Clicking one pre-fills the input — press Enter to send.

​
Stopping generation

While the assistant is streaming a response, a “Stop generating” button appears above the input. Click it to abort the current response.

​
Message history

Your conversation history loads automatically when you open the chat page. Messages persist across sessions in your sandbox — close the tab and come back later, and your history is still there.

​
Offline states

If your sandbox isn’t running, the chat page shows a status message instead of the input:
  • No instance set up — Links to the onboarding page to create your sandbox.
  • Instance paused — Links to the Integrations page to resume.
  • Setting up / Resuming — Shows a loading animation while your sandbox starts.
