PolyAI Local – Multi-Model Chat (Node.js)

A simple Node.js application that lets you ask questions to multiple LLM providers in one place — including OpenAI (ChatGPT), Claude, Gemini, and Grok.

This project was inspired by https://polygpt.io/, but built to run locally with your own API keys for full control and privacy.

• Interactive API key setup (no manual .env editing)

First Run Experience

When you start the app for the first time:

• You will be prompted to enter your API keys directly in the UI
• The app will automatically generate and store them for future use
• No manual .env setup required

---

Usage

Once running, the app will:

1. Prompt you for a question
2. Send the query to all configured providers
3. Return responses from each model

This makes it easy to compare outputs across different LLMs in real time.
