CopilotKit <> PydanticAI Starter

This is a starter template for building AI agents using PydanticAI and CopilotKit. It provides a modern Next.js application with an integrated investment analyst agent that can research stocks, analyze market data, and provide investment insights.

Prerequisites

• OpenAI API Key (for the PydanticAI agent)
• Python 3.12+
• uv
• Node.js 20+
• Any of the following package managers:
  • npm (default)
  • pnpm
  • yarn
  • bun

Getting Started

1. Install dependencies using your preferred package manager:

# Using npm (default)
npm install

# Using pnpm
pnpm install

# Using yarn
yarn install

# Using bun
bun install

Note: This will automatically setup the Python environment as well.

If you have manual issues, you can run:

shCopy

npm run install:agent

2. Set up your OpenAI API key:

Create a .env file in the project root with the following content:

OPENAI_API_KEY=sk-...your-openai-key-here...

3. Start the development server:

# Using npm (default)
npm run dev

# Using pnpm
pnpm dev

# Using yarn
yarn dev

# Using bun
bun run dev

This will start both the UI and agent servers concurrently.

Available Scripts

The following scripts can also be run using your preferred package manager:

• dev - Starts both UI and agent servers in development mode
• dev:debug - Starts development servers with debug logging enabled
• dev:ui - Starts only the Next.js UI server
• dev:agent - Starts only the PydanticAI agent server
• build - Builds the Next.js application for production
• start - Starts the production server
• install:agent - Installs Python dependencies for the agent

Documentation

The main UI component is in src/app/page.tsx. You can:

• Modify the theme colors and styling
• Add new frontend actions
