How to Build a Google Workspace AI Assistant

Building a Google Workspace AI assistant involves integrating various tools and APIs to enhance productivity while ensuring user data security and compliance with Workspace permissions. The architecture for such an assistant typically includes a frontend interface, a backend API for user authentication and state management, an OAuth layer for secure access, and a tool service that wraps Google APIs like Drive, Docs, Gmail, and Calendar. It also involves an LLM layer for generating structured responses and a policy layer to enforce safety and approval protocols. Critical considerations include starting with a narrow set of functionalities, such as read-only searches and draft creations, and expanding gradually while maintaining strict security measures like incremental authorization and audit logs. The assistant should respect user permissions, avoid unsafe actions, and allow user approval for changes. Monitoring and evaluating the assistant's performance through eval sets and logging are essential to ensure reliability and safety in production environments.
