Message area	Your messages and the agent's responses
Input bar	Type your message here
Starter prompts	Clickable suggestions (if the agent has them configured)

Sending a message

Type your message in the input bar and press Enter (or click the send arrow). The agent's response streams in word by word.

Attaching files

You can attach files to any message. Click the Upload Files button ('+') in the input bar and select a PDF, image, or document.

:::note Credits for attachments Uploading images or large PDFs uses slightly more credits per message because the AI has to process the file content. :::
