Gemini App Now 让用户编辑文档和 PDFs In-Chat
在 Google 上的首选来源中添加 Unite.AI
Google 宣布 2026年10月29日，Gemini应用用户现在可以直接在聊天内生成，预览和编辑文档，PDF，演示文稿，电子表格，代码等文件。 更新内容在公司Gemini App博客的一篇文章中详述，今年四月
根据公告，所有用户在Gemini app可用的所有语言中都可以获得这些能力。
在 Gemini 聊天中编辑文件
在新更新下，在Gemini对话中创建的文件不再需要离开聊天来修改。 用户可以生成一个文件，预览它的位置，并编辑它而不切换到单独的应用程序。 Google在公告中描述了三个编辑力学：将一个文件扩展为全屏幕，让用户可以直接输入编辑内容，在文件中突出文字以询问所选段落，并指示Gemini自己完善文件的内容。
Google的公告包括一个以学习指南为主的范例。 一个用户可以上传手写讲座指出，并要求Gemini从他们那里创建PDF研究指南。 一旦指南存在，用户可以手动编辑，突出特定章节，让Gemini在这些章节中修改文本或视觉，并就材料提出更多问题。 公司将该序列作为应用程序内部的单个连续会话，而不是工具之间的交接。
增加直接编辑会改变Gemini会话内的分工。 生成，预览，和修订现在都在同一界面中进行，Gemini可以根据请求修改文件的选定部分，而用户则保留在全屏上手动输入更改的能力。
支持的格式和平台可用性
新编辑能力下的格式支持按平台划分。 Gemini应用的网络和移动版本都支持PDF预览和编辑。 公告中命名的所有其他格式(Google Docs,Google Sheets，幻灯片甲板，Markdown文件，TXT文件，和代码)仅支持在网络上。
拆分是指手机或平板电脑上的用户可以在Gemini聊天中预览和编辑PDF，同时与Google Doc合作，电子表格，幻灯片甲板，Markdown文件，或通过同一编辑机理的纯文本文件，或代码需要网页版本的应用程序。 Google表示，在Gemini应用程序可以使用的所有语言中，这些能力正在向所有用户滚动，在公告中没有分级或分级的可用时间表。
从文件生成到文件编辑
十月更新基于2026年4月29日的一个文件生成功能Google 宣布，当时公司称 Gemini可以从一个快讯直接在聊天中创建PDF,Microsoft Word和Excel文件，Google Docs, Sheets，以及幻灯片。 这之前的更新是Gemini App的集团产品经理Maryam Sanglaji的推出，并提供给当时全球所有Gemini应用用户。
4月的公告将文件生成设定为从脑暴向完整文件移动的方式，而不离开Gemini应用，消除复制，粘贴，并重新调整应用程序之间转移工作所涉及的步骤。 其实例包括将拟议预算出口到Microsoft Excel文件，将松散的想法编成一个圆形的草稿，以及将长时间的合作合并为一页的PDF或Microsoft Word文件。 对于大多数格式来说，用户可以直接将生成的文件下载到他们的设备，或者导出它到Drive.
4月支持的格式列表涵盖了工作空间文件——Docs, Sheets, and Slids——连同.pdf,.docx,.xlsx,.csv,LaTeX，纯文本，丰富的文本格式，以及Markdown. 在该版本的特性下，Gemini生产了文件，用户将其输出；编辑发生在别处。 十月公告新增该生成能力之上的编辑层，因此文件现在可以在创建时的同一聊天内部进行修改，无论是通过用户在全屏上打字，通过突出一个段落来引导一个问题或者在它上更改，还是通过让 Gemini 完善整个文件。
在Gemini app可提供的所有语言中，所有用户都能实时获得编辑能力，其中PDF编辑支持在网络和移动上，其余支持格式在网络上可用。

Gemini App Now Lets Users Edit Documents and PDFs In-Chat
Add Unite.AI to your preferred sources on Google
Google announced on October 29, 2026 that Gemini app users can now generate, preview, and edit documents, PDFs, presentations, spreadsheets, code, and other files directly within a chat. The update, detailed in a post on the company’s Gemini App blog, extends the file-generation capability Google first introduced in April of this year by adding in-place editing, full-screen preview, and text highlighting to the workflow.
The capabilities are available to all users in all languages where the Gemini app is available, according to the announcement.
Editing Files Inside a Gemini Chat
Under the new update, a file created in a Gemini conversation no longer needs to leave the chat to be revised. Users can generate a file, preview it in place, and edit it without switching to a separate application. Google described three editing mechanics in the announcement: expanding a file to full screen so users can type edits directly into it, highlighting text within a file to ask questions about the selected passage, and directing Gemini itself to refine the file’s contents.
Google’s announcement includes a worked example built around a study guide. A user can upload handwritten lecture notes and ask Gemini to create a PDF study guide from them. Once the guide exists, the user can edit it manually, highlight specific sections and have Gemini make changes to the text or visuals in those sections, and ask further questions about the material. The company presented the sequence as a single continuous session inside the app rather than a handoff between tools.
The addition of direct editing changes the division of labor inside a Gemini session. Generation, preview, and revision now occur in the same interface, with Gemini available to modify selected portions of a file on request while the user retains the ability to type changes by hand at full screen.
Supported Formats and Platform Availability
Format support under the new editing capabilities is split by platform. PDF preview and editing are supported on both the web and mobile versions of the Gemini app. All other formats named in the announcement (Google Docs, Google Sheets, slide decks, Markdown files, TXT files, and code) are supported on the web only.
That split means a user on a phone or tablet can preview and edit PDFs inside a Gemini chat, while working with a Google Doc, a spreadsheet, a slide deck, a Markdown file, a plain text file, or code through the same editing mechanics requires the web version of the app. Google stated the capabilities are rolling out to all users in all languages where the Gemini app is available, without a tiered or staged availability schedule in the announcement.
From File Generation to File Editing
The October update builds on a file-generation feature Google announced on April 29, 2026, when the company said Gemini could create PDFs, Microsoft Word and Excel files, Google Docs, Sheets, and Slides directly in a chat from a prompt. That earlier update was introduced by Maryam Sanglaji, Group Product Manager for the Gemini App, and was made available to all Gemini app users globally at the time.
The April announcement framed file generation as a way to move from a brainstorm to a complete file without leaving the Gemini app, eliminating the copy, paste, and reformatting steps involved in transferring work between applications. Its examples included exporting a budget proposal to a Microsoft Excel file, arranging loose ideas into a bulleted draft, and consolidating a lengthy collaboration into a single-page PDF or Microsoft Word document. For most formats, users could download the generated file directly to their device or export it to Drive.
The supported format list in April covered Workspace files — Docs, Sheets, and Slides — along with.pdf,.docx,.xlsx,.csv, LaTeX, plain text, rich text format, and Markdown. Under that version of the feature, Gemini produced the file and the user exported it; editing happened elsewhere. The October announcement adds the editing layer on top of that generation capability, so the file can now be revised inside the same chat where it was created, whether by the user typing at full screen, by highlighting a passage to direct a question or change at it, or by having Gemini refine the file as a whole.
The editing capabilities are live for all users in all languages where the Gemini app is available, with PDF editing supported on web and mobile and the remaining supported formats available on the web.
