What is Replit Agent?
Agent is your creative partner. Agent takes your ideas, helps you refine them, and then makes them real. Unlike a chatbot that only answers questions, Agent takes action: it sets up your project, creates applications, checks its work, and fixes problems along the way. Describe what you want in everyday language. No code or technical knowledge required. Agent handles the rest, from planning to deployment.How to use Replit Agent
Getting started
Describe what you want
In your Replit Workspace, just start chatting. Describe an app you want to build, ask a question, research a topic, or pull data from connected services like BigQuery, Slack, or Notion. There are no constraints. Replit Agent handles whatever you throw at it.
Choose what to build
Optionally, select a project type: web app, mobile app, slides, design, data visualization, and more. If you already described what you want in step 1, Agent figures out the right setup automatically.
Agent builds it
Agent writes code, sets up infrastructure, and tests the result. Once you’re in your project, you can switch between Agent modes to control how it builds.
You’re not locked into one type. Start with a web app and add a mobile app, slides, or a video later — all in the same project.
Plan mode
Enable Plan mode to brainstorm, ask questions, and map out your project before Agent changes any code or data. In Plan mode, Agent will:- Break down complex projects into ordered task lists
- Explore different approaches and weigh trade-offs
- Review and refine before any code is written
Agent modes
Choose how Agent builds your project:- Lite: Make lightweight, inexpensive changes quickly. Lite mode is ideal for visual tweaks, bug fixes, and scoped features
- Autonomous: Use Agent’s full capabilities. Pick Economy for cost-efficient builds or Power for the most capable models. Toggle optional features:
- App testing for automated browser testing
- Code optimizations for the Agent to review its own code
- Turbo for up to 2.5× faster builds using the fastest models. Best suited for larger tasks where speed matters most. Turbo can cost up to 6× more than Power mode (Pro only)
- Max: Long-running, hands-off building experience for complex projects
Tip: You can also enable Plan mode to review and iterate on Agent’s plan before building begins.
What you can build with the Replit Agent
- Web apps, mobile apps, data dashboards, and AI-powered tools
- Visual designs and prototypes — explore mockups on the Design Canvas before committing to code
- Multiple outputs in one project — web apps, mobile apps, slides, and videos sharing the same backend
- Files and documents — CSVs, PDFs, PowerPoint files, Markdown docs
- Connected service queries — pull data from BigQuery, Linear, Slack, Notion, and more directly from chat

Frequently asked questions
Do I need to know how to code?
Do I need to know how to code?
No. Agent handles all the technical work — writing code, setting up infrastructure, configuring databases. You describe what you want in plain language and Agent builds it.
What's the difference between Lite, Autonomous, and Max?
What's the difference between Lite, Autonomous, and Max?
Lite is for quick, targeted changes (10–60 seconds) — visual tweaks, bug fixes, and scoped features. Autonomous is the full Agent experience with Economy and Power tiers, optional App testing, Code optimizations, and Turbo. Max is for long-running, hands-off builds on complex projects.
Can I build more than one thing in a project?
Can I build more than one thing in a project?
Yes. You can add web apps, mobile apps, slides, videos, and data visualizations to the same project — all sharing the same backend and data.
What happens if Agent makes a mistake?
What happens if Agent makes a mistake?
Agent tests its own work on a regular basis. Agent also creates checkpoints as it works, so you can roll back to any previous state. You can also chat with Agent to describe what went wrong and it will fix the issue.
