Your app, inside ChatGPT and Claude
Build ChatGPT plugins
and MCP Apps.
Your components and APIs become a ChatGPT plugin that opens from the sidebar and answers in your own UI. You define the tools; we generate and host the MCP server. The same publish runs in Claude.
Start with a prompt
Your design system.
In the conversation.
Your agent doesn't type back. It shows you. Product cards, dashboards, galleries, video, 3D, rendered in the conversation as your actual interface, not a wall of text. And it's governed: it can render only components you approved, enforced on every render.
Built on MCP Apps, the standard ChatGPT plugins use.
ChatGPT apps and plugins run on MCP and its MCP Apps extension, the open standard Metabind is built on. Press publish and Metabind generates an MCP server from your tools, then hosts, scales, and monitors it. One publish runs in ChatGPT, Claude, and every MCP host.
Inline or fullscreen.
Your Interactive Tools render right in the chat, or take over the screen for a full catalog, a dashboard, or a checkout.
From the sidebar.
Your app opens from the ChatGPT sidebar or as a tab in the conversation. You choose how in Metabind Studio.
Nothing to provision.
No transport code, no host conformance, no deploy pipeline. Every publish is versioned, with one-button rollback.
Already have an app? It's three steps from ChatGPT.
Convert
Your coding agent converts your SwiftUI, Jetpack Compose, or React components, or a Figma file, into BindJS. The Metabind CLI imports them into your workspace and wraps your REST or GraphQL endpoints as tools. Your design system carries over. Only the syntax changes.
Playground
Talk to your agent before your customers do. The Playground in Metabind Studio runs your tools live, so you can change a component or the agent's script and see the result in the same pass. To test on a real device, point the Assistant SDK at your draft endpoint and run your own app.

Publish
One button. Metabind generates, hosts, and scales the MCP server. Then publish to ChatGPT: connect its MCP URL, or submit it for the directory. The same publish runs in Claude and inside your own app.
The same agent, inside your own app.
The Assistant SDK drops the same governed agent into your iOS, Android, and web app: same tools, same script, your brand. On iOS and Android, your components render as native SwiftUI and Jetpack Compose.
Common Questions
What are ChatGPT plugins?
Apps that run inside ChatGPT. A plugin opens inline in the conversation, fullscreen, or from the ChatGPT sidebar, and shows your own interface instead of a wall of text. The new generation, which OpenAI calls plugin extensions, is built on MCP Apps, the open standard Metabind runs on. Metabind turns the components and APIs your app already has into one, and hosts it for you.
Does it work in ChatGPT today?
Yes. Connect your published project to ChatGPT with its MCP URL. Your Interactive Tools render inline or fullscreen, and your app can open from the ChatGPT sidebar or as a tab in a conversation.
Can I publish it to ChatGPT's app directory?
Yes, you can submit it. Metabind handles the domain verification ChatGPT requires. Listing in the directory then goes through OpenAI's own submission and review, which sets its own requirements and timeline. Stuck? Our support team can help.
Do I have to write an MCP server?
No. You define the tools; Metabind generates, hosts, and scales the server.
Does the same app work in Claude?
Yes. One publish runs in ChatGPT, Claude, and every MCP host, and inside your own app through the Assistant SDK.
Do I have to rebuild my app?
No. It's an easy drop-in. Your AI coding agent converts your existing components into BindJS, from SwiftUI, Jetpack Compose, React, or a Figma file, and the CLI imports them into Metabind. Your APIs become Data Tools, and you author the agent's scripts in Metabind. We generate and host the MCP server; you keep your app. Deconstructed, not rebuilt.
What's the free tier?
Starter is free and includes Metabind Studio, BindJS, and the Assistant SDK, with 10K tool invocations included to ship a working assistant. No credit card.
