Everything you need to know to get started.

Agent Builder is a no-code platform for creating and publishing AI apps that respond with charts, cards, tables and forms, not just text.

You can connect your data, customize how the agent looks and behaves, and publish it as a live website copilot or standalone AI app in minutes.

Agent Builder is for anyone who wants to create an AI app using their own data and share it with others or embed it into a website.

Whether you run a startup, a SaaS product, an online store, or just have documents or data you want people to explore, you can build an assistant that feels like a real interactive experience.

No.

You can build, customize and publish your agent entirely through the Thesys interface. Just connect your data, set instructions and click Publish.

If you want more control later, everything is powered by the C1 API, but it is completely optional.

  1. Go to thesys.dev/agent-builder
  2. Connect your data source, upload files, or enter a URL
  3. Click Publish
  4. Copy the embed snippet and paste it into your site

Your copilot goes live instantly and starts responding to visitors with UI.

Normal chatbots return text.

Thesys agents return interactive UI.

That means instead of reading long answers, users see charts, product cards, comparison tables and forms they can use immediately. This turns conversations into real actions instead of dead ends.

Thesys uses usage-based pricing. You only pay for what your agents generate, including the charts, cards and forms they create for users. You can start for free and add credits as your usage grows. Learn more on our pricing page.
