Replit Ghostwriter is Replit's AI coding line inside its browser IDE, and the public ghostwriter URL now highlights Replit Agent for building production-ready apps through chat. You describe an app or site, refine it in conversation, and Agent can search the web, connect Stripe or OpenAI, use built-in database and auth, and test its own work in a browser loop before you publish.

Compared with standalone autocomplete plugins, Replit bundles the editor, hosting, database, and agent workflows in one workspace. Agent adds Extended Thinking and High Power model options for harder tasks, plus automations that can talk to Slack or email. The trade-off is effort-based credits: heavy Agent builds consume monthly allowances faster than simple Ghostwriter completions.

Starter is free with daily Agent credits and one published project. Core costs $20 per month billed annually ($25 monthly) and includes $25 of monthly credits plus up to 5 collaborators and 2 parallel agents. Pro is $95 per month billed annually with $100 credits, 15 collaborators, 10 parallel agents, and 28-day database rollbacks. Students, indie builders, and small teams are the core audience.
