FAQ
How to Use ChatBox — Your AI Assistant

  • 1. What is ChatBox, and how does it work?

    ChatBox is a model-agnostic AI workspace where you can work with multiple AI models, tools, files, and assistants without restarting tasks or losing context.

    How it works

    • ChatBox uses a single persistent chat ("Superchat") that keeps your messages, files, and task context connected over time.
    • You can freely switch between different AI models mid-task while keeping the same conversation, uploads, and progress.
    • The workspace supports text, images, voice input, PDFs, scans, and other files in one continuous flow.
    • For complex tasks, you can activate specialized AI assistants with predefined reasoning and output formats.
    • ChatBox works across mobile and web, syncing your chats and files so you can continue working on any device.

    Example

    Paste a long article and ask: "Summarize this in bullet points and highlight key insights."

    Hint

    You can switch AI models directly from the model selector in the chat interface.
