Microsoft's latest prod to use Copilot AI in the Edge browser is subtle, but still annoying - and I'm getting fed up with this (www.techradar.com)

Microsoft has started surfacing a small "Try Copilot" button in the Edge address bar when users visit rival AI sites like ChatGPT, Perplexity and Deepseek. Clicking it opens Copilot in Edge’s sidebar — a subtle but deliberate nudge to redirect traffic to Microsoft’s LLM service. The behavior is inconsistent (it sometimes appears only on repeat visits) and notably absent on Google’s Gemini page, but it continues a pattern of browser-level product promotion that includes earlier, more aggressive prompts (e.g., pop-ups discouraging Chrome downloads). For the AI/ML community this matters because browser and OS integration become a lever for shaping which models users try, influencing adoption, evaluation comparisons and ecosystem competition. Technically, the UI element is a toolbar icon at the far right of the URL bar that launches Copilot in the sidebar; users can disable it by visiting edge://settings/appearance/copilotAndSidebar → App specific settings → Copilot → toggle off “Show Copilot button on the toolbar”. The move underscores how platform owners can steer traffic to embedded LLMs, raising UX and competitive implications for third-party AI services and researchers benchmarking or deploying alternative models.
