You can now build AI apps within the Claude environment. The feature is currently only available in beta.
Anthropic allows users to build, host, and share AI apps in the Claude app. They can describe their ideas in natural language, after which Claude automatically generates code. The apps run entirely within Claude itself and require no separate API keys or costs, Anthropic writes in a blog post.
The User Pays, not the Developer
When someone uses your AI app, the usage counts towards their own Claude subscription. As a creator, you don’t have to pay for its use by others. The apps are shared via a link and Claude handles everything itself according to Anthropic: from prompt engineering to error handling.
Users have already built learning tools that adapt to the user’s knowledge level, data analysis platforms that process CSV files with natural language, and writing assistants for technical documentation or scenarios. Some apps combine multiple Claude requests in a workflow.
Limitations During the Beta Period
The feature is still in beta and thus has limitations: there are no external API calls or permanent storage yet. It currently only works with text-based API. The feature is available to all Claude users with a Free, Pro, or Max subscription.
Anthropic has recently not only launched Claude Opus 4 and Sonnet 5, but also ensured that Claude can talk back in the mobile app. Users have a choice of five voices and free accounts have a limit of twenty to thirty spoken messages per day.
