Empowering every developer with plugins for Microsoft 365 Copilot | Microsoft 365 Blog (2023)

Generative AI models are ushering in the next frontier in interactions between humans and computers. Just like graphical user interfaces brought computing within reach of hundreds of millions of people three decades ago, next-generation AI will take it even further, making technology more accessible through the most universal interface—natural language.

Microsoft’s approach to generative AI is focused on keeping humans at the center and augmenting human agency. It’s not an autopilot approach, but rather a design ethos that we call Copilot to tackle the growing volume of digital debt that is taking attention away from innovation and sapping our productivity. According to Microsoft’s latest Work Trend Index research, the inflow of data, emails, meetings, and notifications has outpaced our ability to process it all. Workers are spending two full days of the work week managing email and attending meetings—just to keep up. While 49 percent of people said they’re worried that AI will replace their jobs, even more—70 percent—would delegate as much work as possible to AI to lessen their workloads.

Today, I’m excited to announce extensibility for Microsoft 365 Copilot with plugins. With this announcement, we’re empowering every developer to integrate their apps and services into Microsoft 365 Copilot. Together, we can reach hundreds of millions of people where they work every day to create a whole new way of work.

Microsoft 365 Copilot: Your copilot for work

Earlier in March, we announced Microsoft 365 Copilot which brings the power of next-generation AI to Microsoft 365 products like Microsoft Teams, Outlook, and more. Microsoft 365 products are among the leading productivity, communications, and collaboration solutions in the market today.

Microsoft 365 Copilot combines the power of foundation models with your data in Microsoft Graph and Microsoft 365 apps to turn your words into the most powerful productivity tool on the planet. You experience Microsoft 365 Copilot in two ways: in-app assistance and cross-app intelligence to unleash creativity, unlock productivity, and uplevel skills.

The success of our products, like Teams, with more than 300 million active users, would not be possible without our vibrant community of developers and partners. You’ve been a key part of this journey, building the ecosystem with us, with apps that run on and extend our products. As I look at this next-generation AI opportunity, I’m most excited about what we can do together.

Today, we’re announcing the extensibility model for Microsoft 365 Copilot with plugins. Developers can now integrate their apps and services into Microsoft 365 Copilot with plugins to reach hundreds of millions of people where they work every day. Plugins are tools that augment the capabilities of AI systems, enabling them to interact with APIs from other software and services to retrieve real-time information, incorporate company and other business data, and perform new types of computations.

There are three types of plugins for Microsoft 365 Copilot: ChatGPT plugins, Teams message extensions, and Microsoft Power Platform connectors—enabling developers to use existing software and tooling investments and skills.

With Teams Toolkit for Visual Studio, Visual Studio Code, and CLI, developers can create Teams message extensions today that will function as plugins for Microsoft 365 Copilot. We are introducing new capabilities in Teams Toolkit to make it easy to create, test, and debug plugins. Developers can bring any API described by the OpenAPI specification to Microsoft 365 Copilot quickly with the plugin creation experience in Teams Toolkit, available in private preview today.

Developers can control and customize the user experience when their plugin is invoked through Adaptive Cards. Based on the metadata in the OpenAPI specification, Teams Toolkit scaffolds a plugin containing a manifest and declarative Adaptive Cards that define the Copilot user experience. Developers can further customize the manifest and cards to fit their scenario, such as configuring authentication settings, before testing their plugin in Copilot.

See the new tooling in action below, and sign up for the developer early access program to try it out.

Supercharge your data with Semantic Index for Copilot

Microsoft Graph is the gateway to customers’ productivity and collaboration data, as well as their compliance, security, and privacy policies. Copilot grounds the user prompts and responses with the Microsoft Graph data and inherits security and permissions at runtime. This enables an approach to security and governance that our customers control. Furthermore, the data stays in the customers’ tenant and is not used for training Microsoft’s foundation Models.

Microsoft Graph Connectors are Generally Available

The recently announced Semantic Index for Copilot is a sophisticated map of user and company data and powers how Microsoft Graph data is surfaced to Copilot. It computes vector embeddings from Microsoft Graph data to capture semantics and similarities around content and users and enables fast semantic search by Copilot across billions of items in a vector index. Developers can bring their data to Microsoft Graph with Graph connectors to take advantage of the Semantic Index for Copilot to deliver more personalized and actionable responses.

In addition to productivity and collaboration data in Microsoft Graph, Microsoft 365 Copilot can now also access structured data from Microsoft Dynamics 365 and Microsoft Power Platform stored in Microsoft Dataverse. This means copilot responses will be grounded in your business data in addition to user data in Microsoft Graph. Customers in the Microsoft 365 Copilot Early Access Program will be able to try out this capability as we roll out Microsoft 365 Copilot in the program. Developers can import data into Dataverse through Microsoft Power Platform connectors. Watch a demo below of what’s possible with access to business data in Dataverse. Read this blog to learn more.
