How Tencent WorkBuddy’s Human-AI Dual Writing Edits Documents in Place

Tencent’s WorkBuddy V5.3.5, released with Tencent Docs on July 30, 2026, positions AI as an editor inside the document rather than a separate chatbot. A user opens a Tencent Doc or a compatible local Office file, selects the portion that needs attention, and gives an instruction in natural language. The resulting change is written back into the original document for the user to inspect and refine. 1711

The core workflow: select, instruct, review

The feature—described by Tencent as “Human-AI Dual Writing”—is built around a deliberately narrow editing scope. Instead of asking an AI to regenerate an entire report, users can select a paragraph, a spreadsheet range, a PowerPoint page, or another targeted area and specify what should change. Reported instructions include optimizing wording, adding content, generating a chart from selected data, or adjusting a slide’s structure and content. 3711

That selection is the practical control mechanism. It tells the AI which part of the file is in scope, while leaving the rest of the document available for the user and other collaborators to keep editing. Tencent-related reporting says the edits appear directly in the original file, where users can take over manually or add comments for further revision. 711

Which files it supports

WorkBuddy V5.3.5 supports Word, Excel, PowerPoint and Markdown formats, and is described as working with both local Office files and Tencent Docs online documents. 113

This matters because the same interaction model can follow a document between local work and online collaboration: open the file in WorkBuddy, select the relevant region, ask for a change, then continue editing the result in the document. Reports characterize the experience as avoiding the usual copy-and-paste loop between an Office file and a separate AI chat interface. 711

What users can ask the AI to do

Text and Markdown

For prose, the most directly supported uses are local rewriting and content expansion. A user can select a market-analysis paragraph for wording improvements or mark a blank area of a report and ask the AI to supplement a relevant section. 3

These are targeted editing tasks, not an assurance that the system will preserve every aspect of complex document formatting in every file. The available reports support localized edits intended to avoid affecting unselected content and layout, but they do not provide independent benchmark evidence for formatting fidelity across all Office features. 7

Excel and other spreadsheets

Spreadsheet work can be grounded in a selected data region. Reported examples include selecting a table for analysis and chart generation; Tencent-related coverage also describes batch processing for formula-related work. 37

Claims about anomaly detection or sophisticated data cleaning should be treated carefully. They are plausible natural-language tasks for an AI spreadsheet assistant, but the launch reporting provided here most clearly substantiates data analysis and chart-generation examples rather than a complete, independently tested list of analytical capabilities. 37

PowerPoint

For presentations, users can select or designate a PowerPoint page and ask AI to adjust structure and content. Coverage also describes targeting a blank area for layout, imagery and conclusions, which illustrates how an instruction can be tied to a specific place on a slide rather than the entire deck. 7

This supports slide-level editing and content assistance. It does not establish that every form of automatic slide restructuring will be reliable or appropriate without human review.

Images and presentation elements

Some reporting says users can select images and PowerPoint elements as well as text and tables. That expands the model beyond plain-text prompting: the user identifies the object or region, then describes the desired action. 7

Why it is collaborative rather than full-document generation

WorkBuddy’s design leaves key decisions with the human author. The person chooses the document, identifies the area to change, writes the instruction and can edit the output immediately. The AI handles a bounded task; the human remains responsible for the brief, accuracy, judgment and final approval. 711

That is also what makes multi-turn work possible in practice. After an AI edit is added to the file, a user can continue writing or add comments, then ask for another revision based on the document’s current state. Tencent-related coverage says the AI can respond to comments and that users can continue editing after an AI change. 7

Public reporting attributes the underlying document-editing capability to Tencent Docs and the agent interaction to WorkBuddy, but it does not disclose enough technical detail to verify specific Tencent Docs API endpoints, rendering-engine internals or conflict-resolution architecture. The safe conclusion is functional: the integration enables AI-assisted edits inside the live document workflow, rather than a detached output that must be manually transferred back. 111

The practical takeaway

Human-AI Dual Writing is most useful when the author knows where a change belongs but wants help executing it: refine this paragraph, analyze this table, add material in this gap, or revise this slide. Its selection-based approach makes the AI’s role more inspectable and easier to constrain than whole-document regeneration.

For high-stakes documents, users should still verify facts, formulas, charts and visual changes before sharing. The product’s value is not that it removes the editor; it keeps the editor in the document while making repetitive or time-consuming revisions faster.
