Use this interactive demo to learn how to integrate Replit with Claude.

This tutorial shows how to connect Claude to a Replit project using Replit's built-in AI integration, so you can add AI-powered features to your app without leaving your workspace.

Notes:

The built-in Claude integration (Replit-managed) requires a paid Replit plan and bills usage through your Replit credits.
When the Agent detects an Anthropic dependency, it will display a confirmation prompt showing "Anthropic (Replit managed)." Click Approve to let Replit handle the API credentials automatically.
Your Anthropic API key is automatically stored in the Secrets pane. You can update or replace it there at any time.
See How to Set Environment Variables in Replit for more on Secrets.

Sign in at replit.com and open the project you want to add Claude to, or click + Create Something New to start a fresh one.
In the Agent prompt field, describe what you want to build and mention Claude directly - for example: Build a client briefing tool for NEPS Corp that takes a project name and returns a short AI-generated summary using Claude. Click the Arrow button to run.
The Agent generates your project files and wires up the Claude connection. Wait for the build to complete.
Click Run to launch your app. Test it in the Preview tab - for example, Q3 Budget Review, and confirm Claude returns a summary output.

📌 Why this matters

Adding Claude directly to your Replit projects transforms how you prototype AI features. Instead of juggling separate development environments, API documentation, and credential management, you get a streamlined workspace where AI capabilities integrate as naturally as any other dependency. The real advantage goes beyond convenience: when your development environment handles the AI plumbing automatically, you can focus entirely on crafting user experiences and testing different prompts. This accelerated feedback loop lets you iterate on AI-powered features rapidly, making it easier to experiment with creative applications you might not attempt otherwise.
