The AI Tool Already Inside Your Microsoft Apps
Most professionals who use Microsoft 365 — Word, Excel, PowerPoint, Outlook, Teams — do not realise they already have access to one of the most powerful AI tools available.
Microsoft Copilot is built directly into the Microsoft 365 apps that hundreds of millions of professionals use every day. It is not a separate tool you need to learn. It is not a different platform you need to switch to. It is an AI assistant that lives inside the software you are already using — available exactly where your work happens.
In 2026 Microsoft Copilot has matured significantly from its early versions — becoming genuinely useful for a wide range of professional tasks across the entire Microsoft 365 ecosystem.
This guide shows you exactly what Copilot can do and how to use it most effectively in each Microsoft app.
What Is Microsoft Copilot and How to Access It
Microsoft Copilot is available in several forms in 2026.
Copilot in Microsoft 365 — the most powerful version
Integrated directly into Word, Excel, PowerPoint, Outlook, and Teams. Available with Microsoft 365 Business or Enterprise plans that include the Copilot add-on. This is the version described in most of this guide.
Copilot free — at copilot.microsoft.com
A free web-based version of Copilot — similar to ChatGPT — available to anyone with a Microsoft account. Includes web search capability and basic AI assistance. Does not include the deep Microsoft 365 app integration of the paid version.
Copilot in Windows 11
A system-level AI assistant available in Windows 11 — accessible with the Copilot key on compatible keyboards or from the taskbar.
Part 1 — Copilot in Microsoft Word
Word is where most document professionals will get the most immediate value from Copilot.
Draft with Copilot
Open a new Word document. Click the Copilot icon that appears in the document margin. Type what you want to create — a project proposal, a business report, a policy document, a meeting summary. Copilot generates a complete draft based on your description.
Unlike standalone AI tools Word Copilot can reference other documents in your Microsoft 365 environment — pulling in context from your OneDrive files, your emails, and your Teams conversations when generating content.
Rewrite and improve
Select any text in your document. Click the Copilot icon. Choose “Rewrite” to get alternative versions of the selected text — different tones, different lengths, different approaches.
Summarise long documents
Open any long Word document. Open the Copilot chat panel on the right side. Ask: “Please summarise this document” or “What are the five most important points in this document?” Copilot reads the entire document and produces the requested summary.
Ask questions about your document
Use Copilot chat to interrogate your document. “What commitments are made in this contract?” or “What risks are identified in this report?” or “Is there anything in this document that contradicts [specific statement]?”
Part 2 — Copilot in Microsoft Excel
Excel Copilot brings AI to data analysis — allowing professionals to analyse, visualise, and interpret spreadsheet data using natural language rather than formulas.
Analyse your data
Open any Excel spreadsheet with data. Click the Copilot button in the Home ribbon. Ask questions about your data in plain language — “What are the top five values in column B?” or “Show me the trend in revenue over the past twelve months” or “Which products have the highest profit margin?”
Copilot analyses your data and provides answers — often accompanied by charts or formatted tables.
Generate formulas
Ask Copilot to write Excel formulas for you. “Please write a formula that calculates the percentage change between column C and column D” or “Create a formula that highlights any cell in column E where the value is more than 20% above the average.”
Copilot writes the formula, explains what it does, and can insert it directly into your spreadsheet.
Create charts and visualisations
Ask Copilot to create charts from your data. “Please create a bar chart comparing quarterly revenue across the four regions” or “Show me a trend line for monthly website traffic.”
Copilot generates the chart and inserts it into your spreadsheet — formatting it appropriately based on the data.
Identify patterns and insights
Ask for analytical insights rather than specific outputs. “What patterns do you notice in this sales data?” or “What factors seem to be most correlated with high customer satisfaction scores?”
Copilot provides narrative analysis of your data — identifying trends, outliers, and relationships that might not be immediately obvious.
Part 3 — Copilot in Microsoft PowerPoint
For professionals who create presentations regularly Copilot in PowerPoint is one of the most significant time-saving features in the entire Microsoft 365 suite.
Create a presentation from a prompt
Click the Copilot button in PowerPoint. Describe the presentation you want to create — the topic, the audience, the key points, the number of slides. Copilot generates a complete presentation — with slide titles, content, and speaker notes — based on your description.
The generated presentation requires editing and personalisation — but it provides a structured starting point in minutes rather than the hours a from-scratch presentation typically requires.
Create from an existing document
One of Copilot’s most powerful PowerPoint features is the ability to create a presentation from an existing Word document or PDF. Provide the document and ask Copilot to create a presentation based on it.
This feature is particularly valuable for converting reports, proposals, or briefing documents into presentation format — a task that previously required significant manual reformatting.
Summarise a presentation
Open any existing PowerPoint presentation. Ask Copilot “What is this presentation about?” or “Summarise the key messages in this deck.” Useful for quickly getting up to speed on a presentation before a meeting.
Improve individual slides
Select any slide and ask Copilot for specific improvements — “Make this slide more visually engaging” or “Simplify the text on this slide” or “Add speaker notes for this slide.”
Part 4 — Copilot in Microsoft Outlook
For email-heavy professionals Copilot in Outlook produces significant time savings through email drafting, summarisation, and thread management.
Draft emails with Copilot
When composing a new email click the Copilot button in the compose window. Describe the email you want to write — the purpose, the key points, the tone. Copilot drafts the email.
Adjust the draft using the coaching options — make it shorter, make it more formal, make it more friendly — until the tone and length are right.
Summarise long email threads
Click on any long email thread and use Copilot to summarise it. Particularly valuable for catching up on threads you have not read or for getting the key information from a long, complex discussion quickly.
Prepare for meetings from email context
Ask Copilot to help you prepare for a meeting by summarising the email context. “Please summarise the key discussion points and decisions from this email thread so I can prepare for the meeting tomorrow.”
Coaching on email tone
After drafting an email use Copilot to check the tone. “How does this email come across? Is there anything I should change to make it more effective?” Copilot provides tone analysis and specific suggestions.
Part 5 — Copilot in Microsoft Teams
Copilot in Teams addresses one of the most significant productivity drains in modern professional life — the time consumed by meetings and the work required to act on them.
Meeting transcription and summarisation
Copilot can transcribe and summarise Teams meetings in real time — capturing what was discussed, what decisions were made, and what action items were agreed.
After a meeting ask Copilot “Please summarise what was decided in today’s meeting” or “What action items came out of this meeting?” Copilot provides a structured summary based on the meeting transcript.
Catch up on missed meetings
If you could not attend a meeting use Copilot to catch up on what you missed. “What did I miss in the [meeting name] meeting?” or “What decisions were made that affect my work?”
Meeting preparation
Before a meeting ask Copilot to help you prepare. “Please summarise the relevant context from my recent emails and files about [meeting topic] so I can prepare effectively.”
Chat summarisation
In busy Teams channels ask Copilot to summarise recent activity. “What has been discussed in this channel over the past week?” or “What are the key updates I should know about?”
Part 6 — Microsoft Copilot vs Claude and ChatGPT
Understanding when to use Copilot versus other AI tools helps you get the best results from each.
Use Microsoft Copilot when:
You are working within Microsoft 365 apps — Word, Excel, PowerPoint, Outlook, Teams. You need AI assistance that has access to your Microsoft 365 content — your documents, emails, and meeting transcripts. You want to generate presentations or documents without switching to a separate tool.
Use Claude when:
You need the highest quality written output for external-facing documents. You are working on complex analytical tasks that require extended reasoning. You need to process documents outside the Microsoft ecosystem.
Use ChatGPT when:
You need image generation. You want to use custom GPTs. You need a versatile general AI tool outside the Microsoft environment.
The most effective approach for heavy Microsoft 365 users is to use Copilot for in-app tasks and Claude or ChatGPT for tasks that are better suited to standalone AI tools — using each where it performs best.
Getting Access to Microsoft Copilot
Microsoft 365 Copilot — included with certain Microsoft 365 Business and Enterprise plans. Check with your organisation’s IT team or Microsoft 365 admin to see if Copilot is available on your account.

Final Thoughts
Microsoft Copilot’s greatest advantage is not its raw AI capability — Claude and ChatGPT are generally more powerful as standalone AI tools. Its greatest advantage is integration — being available exactly where your work lives, with access to your documents, your emails, and your meetings.
For the hundreds of millions of professionals who use Microsoft 365 daily Copilot represents a genuine productivity opportunity — reducing the time required for document creation, data analysis, email management, and meeting follow-up without requiring any additional tools or workflow changes.
Explore what is available on your Microsoft 365 account. Start with the app where you spend the most time. And build the habit of reaching for Copilot before doing manually what AI can do faster.
