AI coding in browser IDE

What it's used for

Replit with its AI features (formerly branded Ghostwriter) is a browser-based IDE that pairs cloud development with AI-powered code generation, completion, and debugging. It removes the friction of local setup entirely — you can write, run, and deploy code in any language directly from your browser with AI assistance at every step.

  • AI code completion — context-aware suggestions as you type across 50+ programming languages
  • AI chat — ask questions about your code, get explanations, debug errors, and generate new features via conversation
  • Replit Agent — describe an app in natural language and the AI builds it end-to-end, including installing packages and configuring the environment
  • Instant deployment — ship your project to a live URL with zero configuration
  • Multiplayer editing — collaborate in real time with others on the same codebase

Students, educators, hobbyist programmers, and rapid prototypers love Replit because it eliminates environment setup entirely. You can go from idea to deployed app without ever touching a terminal or installing dependencies locally. The built-in AI makes it accessible to beginners while still being productive for experienced developers.

Replit supports Python, JavaScript, TypeScript, Go, Rust, Java, C++, and dozens more languages. Every Repl runs in a cloud container with persistent storage, so your projects are always accessible from any device.

Getting started

  1. Go to replit.com and sign up with email, Google, or GitHub.
  2. Click + Create Repl, choose a language template, and start coding. The AI assistant is immediately available in the sidebar.
  3. Pricing for AI features:
    • Free: Basic AI completions, limited AI chat
    • Replit Core ($20/mo): Advanced AI completions, unlimited AI chat, Replit Agent for building full apps, more compute resources
    • Replit Teams ($25/user/mo): Team management, private Repls, organization-wide AI access
  4. Use Replit Agent: click the Agent tab and describe the app you want to build. The agent installs packages, writes code, and sets up the project autonomously.
  5. Deploy your app: click Deploy in the top bar to get a production URL. Options include Autoscale, Static, and Reserved VM deployments.
Tip: Use Replit's Secrets tab (lock icon in the sidebar) to store API keys and environment variables securely. The AI assistant can access and reference your secrets without exposing them in code.
