CopilotKit has released Open Intelligent UI, a free, open-source project that lets companies add ChatGPT-style interactive answers to their own apps. The company calls it "the open-source alternative" to Intelligent UI, the feature OpenAI added to ChatGPT this week.

Instead of a wall of text, an app built with it can answer with a chart, a map, a 3D model you can rotate or a small working calculator, depending on the question. CopilotKit CEO Atai Barkai announced it on X, describing it as a template that "works with ANY agent."

The timing is deliberate. OpenAI's Intelligent UI arrived with GPT-6 and lets ChatGPT reply with charts, maps and clickable tools. In its launch post, CopilotKit argues that OpenAI's version is closed, works only with OpenAI's models and lives only inside ChatGPT, with "no API to bring it into your own product."

So this isn't something regular ChatGPT users will download. It's a starter kit for developers and businesses that want the same kind of answers inside their own software, like a support chatbot, a travel app or an internal company tool.

CopilotKit's pitch is that those answers should look like the rest of the product. It says the kit works with a company's own design system, existing on-screen components and real data, so a generated chart or form doesn't look like it came from somewhere else.

Here's how it works in plain terms. An AI agent decides whether each answer should be plain text, a table or a custom mini-app. For the custom pieces, it writes web code that runs in an isolated sandbox on the page, and CopilotKit says that code can only load add-ons from an approved list. Users can also download any generated interface as a standalone web page.

It runs on AG-UI, an open standard CopilotKit created for connecting AI agents to apps. The company says developers can swap the included LangChain agent for others, such as Mastra, Google ADK or Microsoft Agent Framework, without rewriting the interface. The code on GitHub is under the MIT license, which allows commercial use.

"Any agent" comes with a catch in the default setup, though. According to the project's own documentation, answers come from OpenAI's chat-latest model out of the box, so you need an OpenAI API key. A second model, Jev from a company called TypeSafe, picks the type of visual for every message and needs its own key. If Jev fails, the answer fails instead of quietly falling back.

Claude and other GPT models can be swapped in for answers. But as shipped, the open alternative to ChatGPT's feature still leans on OpenAI's model.

The project isn't brand new, either. GitHub redirects CopilotKit's earlier Open Generative UI repository to the new name, and the repository dates back to March. Its roughly 1,700 stars include its time under the old name.

Some claims are still unchecked. Barkai's post says it's available on web, mobile and Slack, but the GitHub readme describes a web app and an optional MCP server, with no details on mobile or Slack versions. The readme also notes that demo numbers are illustrations, map routes aren't verified driving directions and results can vary.

Nobody has independently tested how well Open Intelligent UI chooses its visuals. Its own docs call that choice "a model judgment, not a guarantee."
