CopilotKit + Google DeepMind (Gemini) + LangGraph Template

This project showcases how to build practical AI agents with CopilotKit, Google DeepMind’s Gemini, and LangGraph.
It includes two agents, exposed through a Next.js frontend and a FastAPI backend.

✨ Features

  • Post Generator Agent
    Generate LinkedIn and Twitter posts from the context you provide.
    Useful for creating professional, context-aware social content.

  • Stack Analyzer Agent
    Provide a URL and get a detailed breakdown of the site’s technology stack.
    Quickly identify frameworks, libraries, and infrastructure used.

🛠️ Tech Stack

  • Frontend: Next.js
  • Backend: FastAPI
  • Agents: Google Gemini + LangGraph
  • UI Layer: CopilotKit

📌 About

This demo illustrates how CopilotKit can be paired with LangGraph and Gemini to create agents that are:

  • Context-aware (understand the input you provide)
  • Task-focused (generate content or analyze stacks)
  • UI-integrated (feels like part of your app, not just a chatbox)

Project Structure

  • / — Next.js 15 app (UI) in the Project Root
  • agent/ — FastAPI backend agent (Python)

🚀 Getting Started
