What is Replit?
Replit AI is an AI-powered coding assistant integrated into the Replit online IDE that transforms natural language into working code and applications. It provides code completion, AI code assistance, debugging help, and the ability to build full apps and websites through simple chat prompts. The tool includes Replit Agent, which can automatically build apps from descriptions or screenshots, and Ghostwriter for code autocomplete and chat assistance.
Key features include code completion enabled by default, AI code assistance for debugging, natural language to code conversion, Replit Agent for building apps automatically, multiple Agent modes (Lite, Economy, Power), Turbo mode for 2.5x faster performance, screenshot-to-app functionality, built-in database for full-stack apps, and the ability to create slides, videos, and animations. The platform supports 30 programming languages with its custom replit-code-v1.5-3b model trained on 1T tokens.
Replit AI is designed for developers of all skill levels, from beginners exploring coding to professional builders shipping production apps. It serves students, hobbyists, entrepreneurs, designers, and commercial developers who want to go from idea to software quickly without extensive setup or installation. The free tier makes AI coding accessible to anyone, while paid plans cater to serious builders needing more power and collaboration features.
Replit pricing
Pricing model: Freemium
Replit offers four pricing tiers. Starter is free with daily Agent credits, built-in database, ability to create slides/videos/animations, and publish up to 1 project with private/password-protected deployments. Replit Core costs $20/month billed annually ($25/month monthly) and includes everything in Starter plus $25 monthly credits, up to 5 collaborators, up to 2 parallel agents, publishing in any region, unlimited workspaces, and removes the 'Made with Replit' badge. Replit Pro costs $95/month billed annually ($100/month monthly) and includes everything in Core plus $100 monthly credits, up to 15 collaborators, up to 50 viewers, up to 10 parallel agents, access to most powerful models, 28-day database rollbacks, and premium support. Enterprise offers custom pricing with custom seat limits, SSO/SAML, advanced privacy controls, design system support, data warehouse connections, dedicated support, single-tenant environments, region selection, static outbound IPs, and VPC peering.

Frequently asked questions about Replit
What is Replit Agent?
Replit Agent is an AI tool that builds apps and websites automatically from natural language prompts. You can tell it your app idea through simple chat, and it will build it for you without needing code. It's like having an entire team of software engineers on demand. You can also upload a screenshot of an app or website that inspires you, and Agent will build it for you.
How does Replit Agent work?
Replit Agent works by understanding your natural language description of an app or website and automatically generating the code, setting up the environment, and deploying the application. It can work independently with full build mode (requires Core or Pro) or in Lite mode for quick edits on the free plan. The Agent uses different modes (Lite, Economy, Power) to match the task complexity, and Turbo mode for 2.5x faster performance on Pro.
Is Replit AI free to use?
Yes, Replit AI is available for free on the Starter plan. Free users get access to basic AI features including code completion and AI code assistance enabled by default. Starter plan users receive daily credits for Agent usage up to a monthly cap, which reset daily. However, advanced features like Full build mode, third-party connectors, Plan Mode, and removing the 'Made with Replit' badge require upgrading to Core or Pro.
What is the difference between Starter, Core, and Pro plans?
Starter is free with daily Agent credits, 1 published app, and basic AI features. Core ($20/month annually) adds $25 monthly credits, 5 collaborators, 2 parallel agents, unlimited workspaces, any region publishing, and badge removal. Pro ($95/month annually) adds $100 monthly credits, 15 collaborators, 50 viewers, 10 parallel agents, most powerful models, 28-day database rollbacks, and premium support. Each tier includes everything from the previous tier plus exclusive features.
How does Effort-Based Pricing work for Replit Agent?
Effort-Based Pricing updates how Agent charges to better reflect the time and computation used for each request. Previously, Agent charged $0.25 per checkpoint for every task. Now, simple changes still result in a single checkpoint typically costing less than $0.25, while larger or complex tasks are bundled into one checkpoint that may cost more than $0.25 but reflects total effort. This means you pay less for simple requests and may pay more for complex ones, ensuring pricing aligns with actual work performed.
What programming languages does Replit AI support?
Replit AI's custom replit-code-v1.5-3b model supports 30 programming languages. The model was trained on 1T tokens from a code-heavy pretraining mixture that includes a dev-oriented subset of StackExchange. This enables code completion and AI assistance across a wide variety of programming languages commonly used in software development.
Can non-technical people use Replit AI?
Yes, Replit Agent is designed for both technical and non-technical creators. No coding knowledge is needed - you simply tell Replit Agent your app or website idea through natural language chat, and it builds it automatically. The tool is marketed as 'the best tool for ANYONE' and enables people to quickly go from idea to working prototype without writing code themselves.
What happens when I run out of credits?
When you run out of credits on paid plans, you can add pay-as-you-go credits. Starter plan users have daily credits that reset each day up to a monthly cap. Core and Pro users have monthly credits ($25 and $100 respectively) that roll over for one month if unused. Additional usage beyond your plan's credits is billed as pay-as-you-go based on Effort-Based Pricing, where cost reflects the actual effort the Agent uses for each request.
How many collaborators can I invite on each plan?
The Starter free plan does not specify collaborator limits in the visible features. Replit Core allows you to invite up to 5 collaborators with pooled credits and budget controls. Replit Pro allows up to 15 builders (collaborators) with pooled credits and budget controls, plus up to 50 viewers. There are no per-user fees - everyone works from the same plan's credit pool.
What makes Replit AI unique versus other AI coding tools?
Replit AI is unique because it combines an online IDE with integrated AI at every step, requiring no installation or setup. You can go from idea to app entirely in one browser tab. Replit Agent can build full applications from natural language or screenshots, not just provide code suggestions. The platform offers multiple Agent modes for different task types, Turbo mode for speed on Pro, built-in databases, instant deployment, and real-time collaboration. AI is redefining every single Replit feature, making it fundamental to editing and deploying software.
