LLM Chat

Accessing the Chat Panel

The LLM Chat panel appears as a tab in the ZAP Workspace window. You can access it by clicking on the "LLM Chat" tab. +

Multiple Tabs

+The LLM Chat panel supports multiple sub-tabs, allowing you to run several conversations in parallel. Each tab maintains its own conversation history, so you can keep different topics or contexts separate. +

+Click the plus (+) tab to create a new chat tab. Tabs are initially numbered; double-click a tab to rename it. Use the close button on each tab to remove it when no longer needed. +

Tips

    +
  • Use multiple tabs to organize different conversations or topics; each tab keeps its own history.
  • The chat maintains conversation context, allowing for follow-up questions and multi-turn conversations.
  • You can ask questions about security testing, web application vulnerabilities, ZAP usage, or any other topic the LLM can help with.
  • The input area is disabled while a message is being processed to prevent sending duplicate messages.
