Advanced Formatting

Modern chat interfaces are no longer limited to plain text — they can present rich, interactive, and dynamic content directly inside the conversation.

To support this, we’ve introduced a feature that uses custom markdown code blocks to display enriched content such as charts, widgets, or visual summaries. These code blocks follow a simple syntax:

This approach lets developers define structured content using JSON, which is then rendered beautifully in the chat UI depending on the customType.

Additional content types are planned and will be introduced in future iterations of the platform.
