Custom GitHub Copilot with Theia AI – New Video Tutorial

Ever wondered how to build your own GitHub Copilot—customized for your domain and embedded into your specialized tool or IDE? We just published a new video tutorial on YouTube that shows exactly how to do that using Theia AI.

What You’ll Learn

In this short tutorial, we demonstrate how to build a custom, domain-specific AI-powered tool, tailored for domain experts like system engineers, analysts, or developers working with specific models or configuration data. You’ll learn how to:

• Create a Theia-based application using open-source components.
• Integrate a custom AI chat agent powered by an LLM (e.g., OpenAI, Claude, Gemini).
• Equip the agent with tool functions—domain-specific operations the AI can trigger, such as creating or querying structured data.
• Leverage Theia AI to give your tool an intelligent assistant that truly understands your domain model.

This video showcases the flexibility and extensibility of Theia AI enabling you to build your own GitHub Copilot, focused on real, domain-specific workflows and business logic—not only general-purpose coding.

Why It Matters

Domain experts often work with complex systems and need specialized support. Off-the-shelf AI tools aren’t enough. With Theia and Theia AI, you can build a custom, intelligent experience—one that understands your domain, speaks your language, and integrates tightly into your toolchain.

In this video, you’ll see how an AI agent can:

• Create new artifacts based on prompts.
• Answer questions about domain-specific workflows.
• Interact with files and models in your workspace.
• Respond using tailored, efficient logic you define.

And all of this is done in an open, vendor-neutral, fully customizable platform.
