Chrome users cannot natively access Microsoft Copilot's sidebar feature, which is built into Edge. This extension provides a one-click shortcut to open Copilot from Chrome, with header spoofing to make requests appear as if they come from Edge.

User clicks the extension icon (or presses Ctrl+Shift+K) → side panel opens → sidepanel.js immediately opens https://copilot.microsoft.com in a new tab and closes the panel. The background service worker spoofs Edge browser headers and removes CSP/frame restrictions for Bing domains to enable the Copilot experience in Chrome.

Target users: Chrome users who want access to Microsoft Copilot without switching to Edge / Users familiar with Edge's Copilot sidebar who prefer Chrome

The extension is extremely simple (6 text files, ~78 bytes of functional JS). Analysis is straightforward but limited in depth.
Cannot fully verify whether copilot.microsoft.com allows any unauthenticated interaction from the extension's context.
The side panel iframe approach seems partially broken—sidepanel.js immediately opens a tab and closes the window, suggesting the side panel embedding may not work as intended.

Monetization

No paid features detected

The extension contains zero billing, subscription, license, or upgrade-gating code. The only 'upgrade' keyword (background.js line 9) refers to upgrading the Chrome browser version to 114+, not a paid feature. Microsoft Copilot has a paid 'Copilot Pro' tier externally, but the extension does not gate any features or reference payment in any way.

Confidence: 90
Payment platform: --
Source: AI / High
Login required: Yes
Reason: The extension is a launcher that opens copilot.microsoft.com. Microsoft Copilot requires a Microsoft account for interactive AI chat functionality, which is the core use case. The extension itself implements no login UI or authentication logic—login is enforced by the destination service.
