Developers Can Build AI Apps that Authenticate and Bill to the User, Not the Creator

Anthropic has introduced a new feature that allows users to build, host, and share interactive AI-powered applications directly within the Claude app—transforming Claude from a conversational assistant into a full development platform. The functionality lets developers generate Claude-powered artifacts that run code, interact through APIs, and function like standalone apps—all without having to manage deployment infrastructure or scale server loads. Crucially, users of these apps will authenticate with their own Claude accounts, meaning that API usage is billed to them, not the app creator.

Early adopters have already built a wide range of applications using this new system: from AI-powered games with persistent NPC memory, to adaptive tutoring tools, dynamic writing assistants, and CSV data exploration tools powered by natural language prompts. Developers, as noted in anthropic.com, can prompt Claude to build these apps directly, iteratively refine them through conversation, and share them instantly via link—no backend configuration or API key management required. Claude handles all the complexity, including code orchestration, prompt engineering, and error handling.

The apps leverage Claude’s own API and are powered by real code, often structured in React with support for file processing and user interface components. Users can view, fork, and customize any existing artifact, making collaborative app development frictionless. While current limitations include no support for external APIs, no persistent storage, and reliance on Claude’s text-based completion API, the framework is robust enough to support sophisticated workflows—such as chaining multiple Claude calls in agentic pipelines.

The new feature is available in beta across all Claude subscription tiers—Free, Pro, and Max—democratizing access to AI app development. By absorbing the technical overhead, Anthropic is enabling anyone with an idea to quickly bring it to life. Whether for rapid prototyping or sharing interactive AI tools with others, Claude’s in-app development environment represents a major step toward accessible, scalable AI app ecosystems.
