Your organisation has thousands of documents in SharePoint. Most of them are impossible to find. Copilot in SharePoint changes that — turning a passive file store into an intelligent knowledge layer you can search, question, and summarise in plain English.
This guide shows you how to use SharePoint Copilot to find the right document in seconds, get instant summaries without opening files, and pull answers from across your entire intranet.
What Is Copilot in SharePoint?
In 2026, SharePoint Copilot can:
- Search document libraries using natural language
- Summarise any document without opening it
- Answer questions by drawing on multiple documents at once
- Generate SharePoint pages from existing content
- Draft News posts from a short description
Requirements: Microsoft 365 Copilot licence. Works in SharePoint Online within Microsoft 365.
Natural Language Document Search
How to Use It
In your SharePoint site, click the search bar and type what you need in plain English:
- “Find the latest version of the data privacy policy”
- “Show me all project proposals submitted in the last 6 months”
- “Which documents mention the Northbridge account?”
- “Find the onboarding guide for new marketing hires”
Copilot returns results ranked by semantic relevance — it understands synonyms and context, not just keyword matches.
Summarise Documents Without Opening Them
Hover over any document and click the Copilot icon — within seconds you get a plain-English summary, key decisions or recommendations, and any action items mentioned. Review 15 documents in the time it used to take to open three.
Ask Questions Across Multiple Documents
From a document library, open the Copilot pane and ask cross-document questions:
- “What are the key differences between our 2024 and 2026 IT security policies?”
- “What have we decided about Vendor X across all meeting minutes this year?”
- “Summarise all feedback on the new product design across the research documents in this site”
Copilot synthesises answers with citations pointing to specific files. Your SharePoint becomes a knowledge base you can query.
Create SharePoint Pages with Copilot
Generate a Page from Existing Documents
Go to New > Page and use Draft with Copilot: “Create a project overview page using the project charter and status update documents in this library.”
Draft Internal News Posts
When creating a News post, use Copilot: “Write a 200-word announcement about our new flexible working policy launching next month.” A polished draft is ready in seconds.
Best Practices for SharePoint + Copilot
- Keep documents well-named. Descriptive file names in logical libraries improve search quality.
- Use metadata columns. Department, Status, and Project columns enable precise filtering.
- Manage permissions properly. Copilot only surfaces documents the user has access to.
- Use summaries for onboarding. New hires can get up to speed on a project in minutes, not weeks.
Key Takeaways
- SharePoint Copilot turns a passive file store into a searchable, summarisable knowledge layer.
- Use natural language search to find documents by meaning, not just file name.
- Use document summaries to review 10 files in the time it takes to open one.
- Use cross-document Q&A to get synthesised answers from your entire intranet.
- Clean organisation and metadata make every Copilot search more accurate.
