When Tey Bannerman tried explaining what Microsoft Copilot is to someone, he realized he couldn't. The name now covers at least 75 different things. Apps, features, platforms, a keyboard key, a laptop category, and even a tool for building more agentic frameworks. He went looking for a complete list. Nothing. Not on Microsoft's website, not in their documentation. So he pieced it together himself from product pages, launch announcements, and marketing materials, then built an interactive visualization to map the sprawl. Bannerman notes he couldn't find a clear pattern in how Microsoft applies the name. There isn't one. Hacker News commenters compared it to Microsoft's .net branding push around 2002, when they'd slapped that suffix on everything. One joked that 'In Microsoft, everything is a copilot.' The approach makes sense as an umbrella strategy for AI across their portfolio, but it also creates real confusion. You're trying to figure out what a specific Copilot actually does? Good luck. Competitors have taken different paths. Google consolidated from Bard to Gemini across products, but with far fewer distinct branded items. OpenAI keeps model names specific (GPT-4, DALL-E) with ChatGPT as the main consumer brand. Apple went with 'Apple Intelligence' as a unified label. Salesforce does something similar with Einstein, but narrower in scope. Microsoft's approach is the most aggressive by far. Both in scale and in how thoroughly they've pushed one brand name across their entire ecosystem.
