R2 Copilot 是什麼

Chrome 商店介紹

Private AI side-panel Assistant. Per-site context, page-aware chat, one-click insert into Gmail and Outlook drafts. R2 Copilot is a Google Chrome browser extension that provides AI assistance directly within the user’s browsing context. The extension opens as a secure side panel alongside any active webpage, allowing users to interact with AI without switching tabs or leaving the current page. The extension is designed to operate entirely in parallel with the webpage being viewed, ensuring that user context is preserved at all times. AI interactions are initiated explicitly by the user via the extension panel.

Key Capabilities

When the R2 Copilot side panel is open, users can:

Analyze and summarize the content of the currently displayed webpage.
Ask contextual questions about documents, articles, or contracts being viewed in the browser.
Conduct research assistance tasks such as simplification, expansion, or cross‑referencing of on‑screen information.

Side‑by‑Side Interaction Model

Unlike traditional AI tools that require copying content or navigating to separate interfaces, R2 Copilot remains continuously visible next to the webpage. This side‑by‑side model enables:

Immediate AI interaction without interrupting user workflows.
Reduced context switching and minimized risk of copying sensitive data.
Real‑time assistance aligned with the content currently visible in the browser.

Operational Characteristics

The extension is user‑initiated and user‑controlled at all times.
AI actions are performed only when explicitly requested by the user.
No automatic background processing is performed on webpages.
The extension panel can be pinned or closed by the user at any time.

This architecture allows R2 Copilot to function as an in‑context productivity assistant while maintaining clear interaction boundaries suitable for enterprise and compliance‑focused environments.
