Persona Response Comparator (Standalone)

A standalone Streamlit app for comparing LLM responses across different user persona configurations. No FastAPI backend or MongoDB required.

Setup

pip install -r requirements.txt

Run

OPENROUTER_API_KEY=sk-or-v1-your-key streamlit run app.py

Environment variables

Variable	Default	Description
OPENROUTER_API_KEY	(required)	Your OpenRouter API key
MODEL_NAME	google/gemini-2.5-flash	Model to use via OpenRouter

What changed vs. the original

• No FastAPI dependency - the app calls the LLM directly via pydantic-ai + OpenRouter.
• No MongoDB - chat history is kept in Streamlit session state (in-memory, per browser tab).
• Persona prompt built locally - dimension descriptions are embedded in the app instead of being looked up from a database.
