What is AI Chat?

The AI Chat tool allows you to interact with advanced language models to ask questions, draft content, analyze data, or brainstorm ideas. You can type requests, attach supporting files, and receive contextual responses in real time.

Input Types

Text-to-Text

• Enter queries in plain language.

• Supports both short prompts and multi-paragraph requests.

Attachments

• Supported file types: .pdf, .docx, .txt, .jpg, .png.

• File size: up to 25 MB per file.
