The essentials in 30 seconds
- Copilot in Word generates first drafts, rephrases, summarizes and translates directly in the document.
- Gemini in Google Docs offers the same capabilities with better collaborative and Drive integration.
- Time savings: 40 to 60% on writing recurring documents (reports, minutes, long emails).
- Main limitation: factual data (figures, dates, proper nouns) must always be checked manually.
- Best use: first drafts, rephrasings, meeting summaries and tone adaptations.
The problem
Professional writing is time-consuming and often perceived as a brake on productivity. Meeting minutes take 30 to 60 minutes. A summary note requires 2 to 3 hours. A project report can take up a whole day. Yet a large part of this time is devoted to formatting the information rather than to strategic thinking.
Write job descriptions, internal communications, procedures and guides — important documents but with low differentiating value in their production.
Produce activity reports, management notes, committee minutes — often urgently, with stakes around clarity and precision.
Write policies, procedures, template contracts and legal notices — documents with a repetitive structure requiring precision and consistency.
The AI solution
Copilot in Word and Gemini in Google Docs make it possible to speed up each stage of the writing process, from the blank page to the final proofreading.
Break the blank page (first-draft generation)
The most used function. In Word: click the Copilot icon at the top of the page and describe your document. Example: "Write a 2-page remote-work policy for an SMB of 50 people, covering eligibility rules, equipment organization and tracking arrangements, in a professional tone". Copilot produces a first draft in 10 seconds that you only have to adapt.
Summarizing long documents
Upload a reference document (annual report, market study, audit) into Word or Docs and ask Copilot / Gemini to summarize it into 5 key points, into 1 page or by theme. Particularly useful for managers who receive many long documents. Copilot can summarize up to 100 pages in a single pass.
Rephrasing and tone adaptation
Select a paragraph that is too technical, too formal or too long. Ask: "Simplify this text for a non-technical executive", "Make this paragraph more convincing", "Cut this text in half while keeping the essentials". Gemini also offers an "Improve" function that adjusts spelling, grammar and style in a single operation.
Implementation
The 5 most effective prompts for professional writing with Copilot / Gemini:
Structured generation
"Write [document type] of [length] on [topic], intended for [audience], including: [list of desired sections], in a [formal / accessible / persuasive] tone." This prompt gives the best results because it provides all the parameters the AI needs.
Targeted summary
"Summarize this document into [number] key points for [audience], highlighting the practical implications for [specific context]." Add the reader's context to get a truly useful summary rather than a generic one.
Tone adaptation
"Rephrase this text for [target audience], using [simple / technical / persuasive] language, without losing the essential information." Works very well for adapting technical content to general-public communication or vice versa.
Contextual completion
"Based on [reference document in OneDrive/Drive], write the [section title] section of this document consistently with the rest." This approach leverages the AI tools' ability to read several reference documents simultaneously.
Augmented proofreading
"Proofread this document and identify: 1) internal inconsistencies, 2) ambiguous phrasing, 3) passages that are too long. Propose corrections." Contact us for hands-on workshops on these techniques.

Frequently asked questions
Can Copilot in Word write an entire document?
Copilot can generate a structured first draft (5 to 15 pages) from a prompt or from other reference files. The quality of the result depends heavily on the context provided. The generated content always requires human review and validation, particularly for factual data. Copilot excels at documents with a strongly repetitive structure: reports, minutes, specifications.
How to use AI to rephrase without losing your style?
Rephrasing is one of the safest uses of AI in writing. Select a paragraph and ask "Rephrase this text in a more concise style" or "Adapt this paragraph for a non-technical reader". To preserve your style, provide examples of your previous writing as a reference. Avoid chained rephrasings which result in a standardized, impersonal text.
Is Gemini in Google Docs more suited to collaboration?
Gemini in Docs offers a better experience for real-time co-writing, thanks to Google's native integration with comments, suggestions and version history. It also lets you reference other Google Drive documents and Gmail emails. Copilot in Word is more powerful for complex documents with tables of contents, advanced styles and mail merge.

Microsoft launched Copilot Pages in late 2024, a collaborative surface in Microsoft 365 Copilot Chat that lets you create collaborative documents from Copilot responses. Concretely: you ask Copilot a question in Teams or the browser, the answer can be sent into a shareable "Page" with your team, editable in real time, and pushable to Word or OneNote. It's an alternative to Google Docs for Microsoft teams that want smoother collaboration on AI-generated content. See our Copilot training to master these tools.
