As Microsoft (MS) expands its Copilot brand across the board, the number of product lines using the same name is rising sharply. An external developer's tally shows about 80 Microsoft products now carry the Copilot name.

GIGAZINE, an online outlet, reported on April 7 that software developer Tey Bannerman (테이 배너맨) recently released results from collecting and categorising Microsoft's Copilot products. He built the list by combining product pages, launch announcements and marketing materials, and summarised it as a chart that visualises the products by category.

Bannerman said 80 products carried the Copilot name as of late March 2026. They are grouped by function and use into chatbots, enterprise platforms, in-app copilots, desktop applications, hardware, business software and developer tools, among others. In the visual chart, each category is separated by colour to show relationships and positioning at a glance.

One example is Microsoft 365 Copilot Chat, an AI feature integrated across productivity tools such as Word, Excel and PowerPoint. It supports document writing, data analysis and presentation creation. In this way, Copilot is not a single service but is embedded across various product lines or expanded as a standalone service.

A notable point is that Microsoft's official channels do not separately compile a full list of Copilot offerings. Bannerman said, "There is no complete list anywhere in official documents or on the website," and explained that he built the list by gathering individual materials.

The chart he released is interactive, and users can hover over a specific product to see a feature description and its links to other Copilot products. It also supports downloading as an image file so the overall structure can be viewed at a glance.

The list is not a fixed output and is continuously updated. If the community points out missing products, they are added. Bannerman said, "As long as Microsoft keeps adding Copilot products, this list will keep expanding."

In the industry, some say the expansion of the Copilot brand shows one side of Microsoft's strategy to integrate AI functions across its entire product lineup. Some also point out that as the number of products grows quickly, it may become increasingly complex for users to distinguish functions and roles.
