On April 6, Microsoft announced in a blog post that it has officially invited Microsoft365Insider program members to test the new Copilot collaboration feature in iOS version of Word. This feature, previously known as Agent Mode, aims to completely change mobile document productivity through natural language interaction.

Key Highlights: Instant Writing with Natural Language

Users who hold a Copilot license can now directly call the AI assistant in documents:

  • Instruction-driven: Users just need to click on the Copilot icon within the document and input their ideas; the AI will generate a draft or improve existing content based on the instructions.

  • Reference Enhancement: Microsoft introduced a convenient operation technique, allowing users to quickly reference other materials by typing the "/" symbol, making the AI's output more accurate.

  • Instant Optimization: After generating content, users can ask the AI to further adjust the tone, length, or structure.

Collaboration Mechanism: Security First, Reject "Autonomy"

Regarding complex collaboration scenarios in shared documents, Microsoft designed a strict security verification mechanism:

  • Preview Verification: In shared mode, Copilot's modification suggestions will first be shown in the chat window for preview; only after user confirmation will they be applied to the official document.

  • One-click Reversal: If the AI's modifications do not meet expectations, users can use the undo function or quickly restore the original data through historical versions, effectively preventing accidental operations.

Current Limitations: Still Some Room for "Evolution"

Although powerful, the current testing version still has some technical shortcomings:

  • Cannot Start from Scratch: Copilot cannot directly create new documents; users need to manually create files first.

  • Lack of Multimedia Support: It does not support generating images directly within the document; users need to switch to Copilot Chat to complete this.

  • Comment Anchor Vulnerability: Currently, users cannot add or modify comments, and replacing content with anchor comments may accidentally delete original comments.

Industry Insight: "AI Sovereignty" in Mobile Work

As large models like Gemma4 continue to break through in efficiency, major companies are accelerating the integration of AI capabilities into specific application scenarios. This update by Microsoft is not just an addition of features, but also a deep implementation of its "AI First" strategy on mobile devices.
