Some users find Copilot underperforms compared to other AI chatbots, citing examples of nonsensical responses and branding confusion across Microsoft products. Others defend Copilot, sharing successful interactions and suggesting that user error, model selection, or the "nondeterministic" nature of LLMs can explain negative experiences. The conversation highlights Microsoft's branding and product naming issues. Many commenters express frustration over the proliferation of "Copilot" across various applications, creating confusion for users. Concerns about Copilot's capabilities, licensing complexity, and integration with Microsoft 365 are also raised. Some suggest Microsoft may be hindering Copilot's performance to conserve resources. Despite criticisms, some users find Copilot useful in specific contexts, while others praise Google's AI search integration. Overall, the thread underscores the complexities and inconsistencies of current AI tools.
