Embarcadero Launches 'Kai', an AI Agent for RAD Studio

Embarcadero Technologies has launched 'Kai', an AI agent plugin for RAD Studio (Delphi / C++Builder), in the Japanese market as of June 10, 2026. Kai is an agent-based AI that provides end-to-end development workflow support directly within the IDE, ranging from prompt-based application and UI generation to automated compilation error correction.

What is Kai: An AI Development Assistant Integrated into RAD Studio

While RAD Studio previously provided AI assistance through 'Smart CodeInsight', Kai elevates this by functioning as a deeply integrated AI agent. By using a dockable agent chat window, developers can issue instructions for coding, UI generation, compilation, error correction, file operations, and autonomous workflows using the Model Context Protocol (MCP). It supports version control and PR workflows while understanding the project context to manipulate the IDE directly, rather than just providing text responses.

Kai generates code and project updates that adhere to RAD Studio's standards, utilizing established frameworks like VCL, FireMonkey, and FireDAC. It ensures that the generated output is tailored to the specific needs of Delphi and C++Builder development.

Key Features

- Context-Aware Code Suggestions: Goes beyond basic autocompletion by understanding the current implementation intent, offering inline 'Ghost Text' suggestions and side-by-side comparison panels. - Fully Integrated Agent Chat: Allows direct code editing via a chat interface that references project files using the '@' symbol. - Prompt-based App/UI Generation: Instantly generates platform-native UI components and functional prototypes from text prompts. - Automated Compiler Error Correction: Detects compiler errors, suggests or applies fixes, and transitions directly into the re-compilation flow. - Code Modernization: Assists with refactoring, updating UI patterns, and migrating legacy Delphi/C++ code to support the latest platforms. - Flexible AI Model Support: Supports both cloud (OpenAI, Gemini, Claude, GitHub Copilot) and local models (Ollama, LM Studio) via BYOK (Bring Your Own Key). It communicates directly with the chosen backend, ensuring that assets are not passed through an external proxy layer.
