Create and extend custom copilots in Microsoft Copilot Studio

Microsoft Copilot Studio is a graphical low-code tool for creating and maintaining copilots.

A copilot is an AI-powered conversational interface based on large language models (LLMs) and additional sources of knowledge. It’s a powerful AI companion that can handle a range of requests, from providing simple responses to common questions to resolving issues requiring complex conversations.

Copilots can engage with customers and employees in multiple languages across websites, mobile apps, Facebook, Microsoft Teams, or any channel supported by the Azure Bot Service.

Extend Microsoft Copilot for Microsoft 365 with Copilot Studio

As a developer, you can enhance, enrich, and customize Microsoft Copilot for Microsoft 365 in 2 ways: you can extend Microsoft Copilot or build your own copilot.

On its own, Copilot for Microsoft 365 is a powerful productivity tool for keeping users in the flow of their work across Microsoft 365 applications. It provides users with general skills that enhance personal productivity, such as understanding, summarizing, predicting, recalling, translating, and generating content. It draws from a baseline of your organizational knowledge by indexing content into Microsoft Graph, such as the emails, chats, and documents that users have permission to access.

However, business workflows don’t typically run exclusively on Microsoft 365 applications and experiences. With Copilot extensibility, you can augment Copilot for Microsoft 365 with custom actions and ground your responses with connectors that access data in real-time. You can even extend Copilot’s experiences with declarative and custom copilots that focus on specific user experiences.
