Auto Responder Persona and Context Isolation
2025-06-02
New Features
The new Auto Responder Persona watches the conversation you are having with a model and responds to the conversation according to your directions for the persona.
With Auto Responder, you can setup a:
- Fact Checker Persona that fact-checks the conversation
- Deeper research Persona that looks further into a statement being made by a model
- Devil's advocate Persona that argues the counterpoints
- And more!
Also new and related to Auto Responder is the ability to isolate any message from the conversation's context without removing the message. This allows you to really dial in on specific LLM responses in the conversation thread.
Check out the Auto Responder Docs to learn more.
Watch the Youtube demo of Auto Responder and Context Isolation to see it all in action.
