ChatGPT 正式入驻 Word：免费用户可用，办公文档内三套 AI 同台竞争
OpenAI 推出面向 Word 的官方 ChatGPT 插件，全球所有账户方案均可使用，免费用户也能直接体验。功能包括将零散笔记整理成初稿、总结长报告、按受众调整语气、编辑格式和统一术语；付费与企业账户可访问外部材料并保存常用技能复用。免费用户默认使用基础模型，企业用户可在特定时段免费预览高级模型，且 Word 插件配额与 Codex 等工具共享。局限方面：模型仍可能出错，插件仅读取当前文档、不访问其他文件，且与网页版 ChatGPT 的聊天历史不同步。文章还提到同一 Word 窗口内已同时存在微软 Copilot、Anthropic 的 Claude for Word 和 OpenAI 的 ChatGPT for Word，ChatGPT 桌面端新增 Appshots 功能可直接截取任意软件窗口内容发送给 ChatGPT。
AI推荐理由 内容为 AIbase 对 OpenAI 在 Word 中上线 ChatGPT 插件的转述报道，非官方首发，来源为聚合型 AI 资讯站，事实描述较具体（免费用户可用、配额与 Codex 共享、仅读取当前文档、不与网页版历史同步），但缺少官方链接与可验证证据，且发布时间为 2026-09-20 的存储时间，无法确认实际发布节点。兴趣点在于 Word 内同时存在 Copilot、Claude for Word 与 ChatGPT for Word 三套 AI 的竞争格局，以及 ChatGPT 桌面端新增 Appshots 窗口截取功能，对办公 AI 应用与产品落地有参考价值；局限是信息密度一般、含推广栏目与版权尾注噪声，故未给高分。

ChatGPT Officially Joins Word: Free Users Can Also Use It, Three Sets of AI Compete in Office Documents

OpenAI has launched the official ChatGPT add-in for Word, available to all account plans worldwide, allowing even free users to experience it directly. This means another major player has joined the ranks of AI assistants in the most popular word processing software.
The add-in offers features that closely align with writers' daily needs: compiling scattered notes into a first draft, summarizing long reports, adjusting tone for different audiences, editing formatting, and unifying terminology. Paid and enterprise accounts can go further, accessing external materials and saving frequently used skills for repeated use. However, there are different levels of access: free users default to using the basic model, while enterprise users can preview the advanced model for free during specific periods; also, the quota for the Word add-in is shared with tools like Codex, not separate.
Its limitations should also be clarified. The model can still make mistakes, the add-in only reads the current document and does not access other files, and the chat history with the web version of ChatGPT is not synchronized — so it's more like a collaborative partner next to the document, rather than an all-knowing writing brain.
What's interesting is the changing landscape. Now, within the same Word window, there are three AI tools simultaneously: Microsoft's own Copilot, Claude for Word from Anthropic, and ChatGPT for Word from OpenAI. Office software is being reshaped by AI. At the same time, the ChatGPT desktop app has added the Appshots feature, which allows you to directly capture the content of any software window and send it to ChatGPT — the barrier to using AI is being further lowered, and people's role in document writing is shifting from "typing by hand" to "giving instructions, reviewing changes, making judgments, and making decisions."
