How to Use Replit AI Agent

Open your browser and head to replit.com. Replit is a cloud-based IDE — everything runs on their servers, so there is nothing to download or install on your computer.

The homepage shows featured projects and templates. You can explore these later, but first you need an account.

Click Sign Up in the top-right corner. You can create an account with Google, GitHub, or an email address. The free tier gives you access to the IDE, basic compute, and limited AI features.

Replit Core ($25/mo) unlocks the full AI Agent, more compute power, private Repls, and Deployments with custom domains. The free tier is enough to follow this guide and build your first project.

Click the + Create Repl button in your dashboard. You will see two options:

• Template — Pick a language (Python, Node.js, HTML/CSS/JS, etc.) or a framework template (React, Flask, Express). Replit sets up the project structure for you.
• Import from GitHub — Paste a GitHub repo URL and Replit clones it into a new Repl. Great for contributing to open-source projects from your browser.

Give your Repl a name and click Create Repl. The workspace opens with a file tree on the left, editor in the center, and preview/console on the right.

In the workspace, look for the AI button in the left sidebar or the chat panel on the right. Click it to open a conversation with Replit's AI Agent.

The AI Agent is different from a simple chatbot. It can read your entire project, create and edit files, install packages, run commands, and debug errors — all autonomously. You describe what you want, and it builds it.

Type a description of what you want to build. Be specific about features, tech stack, and design. Here is an example:

Build a personal finance tracker with:
- A dashboard showing income vs expenses chart
- Add transaction form with category, amount, date
- SQLite database for persistence
- Clean, modern UI with a dark theme
- Responsive layout that works on mobile

The Agent will create a plan, show you which files it will create, and ask for confirmation before starting. Review the plan and click Approve to let it work.

After you approve the plan, the Agent starts working. You can watch it in real time:

• Files appear in the file tree as they are created
• The editor shows code being written
• The console shows packages being installed and commands running
• The preview panel updates as the app takes shape

If the Agent hits an error, it will try to fix it automatically. If it gets stuck, it asks you a clarifying question. You can also interrupt it at any time to redirect.

Replit's multiplayer mode lets multiple people edit the same Repl at the same time — like Google Docs for code. Click the Invite button in the top-right corner.

You can invite by Replit username or generate a shareable link. Collaborators can edit code, run the app, and interact with the AI Agent in the same workspace.

For bigger teams, Replit Teams provides shared workspaces, permissions, and centralized billing. Individual collaborators are free on any plan.

When your app is ready, click the Deploy button at the top of the workspace. Replit Deployments gives you a production URL with HTTPS, automatic scaling, and zero DevOps.

Choose your deployment type:

• Autoscale — Scales up and down based on traffic. Best for web apps and APIs.
• Static — For static sites and SPAs. Fastest and cheapest option.
• Reserved VM — A dedicated machine that is always on. Best for bots, background jobs, and databases.

Your app gets a .replit.app domain by default. You can connect a custom domain in the deployment settings.
