What Is Microsoft Copilot?
Microsoft Copilot is Microsoft's AI assistant. With the Wave 3 update, Copilot uses multi-model intelligence — drawing on OpenAI's GPT-5 series as well as Anthropic models to select the best model for each task. The multi-model architecture is structurally enabled by the April 27, 2026 amendment to Microsoft's OpenAI agreement (which ended cloud exclusivity through 2032 — see section-4-5). Leadership changes in early 2026 saw Mustafa Suleyman move to lead Microsoft's superintelligence initiative, with Yusuf Mehdi and Aris Andreou (EVP Copilot) taking over the Copilot product direction.
Copilot has historically existed in two forms that are often confused — and as of August 2026 Microsoft is collapsing them into a single app:
-
Copilot (free chatbot) — available at copilot.microsoft.com, built into Windows 11, and integrated into Microsoft Edge. Free for anyone. Provides conversational AI, web search with citations, image generation, and document summarization.
-
Microsoft 365 Copilot — the workplace AI layer added on top of existing Microsoft 365 subscriptions (Word, Excel, PowerPoint, Outlook, Teams). Requires a paid M365 subscription plus the Copilot add-on. This is the version designed for enterprise productivity.
The two apps merge — and five features are being removed
Starting mid-August 2026, Microsoft is folding the consumer Copilot app into Microsoft 365 Copilot as a single application that handles both personal and work accounts, rolling out worldwide on mobile and web. The licensing tiers below do not disappear — free Copilot, Copilot Pro and the M365 Copilot add-on all remain — but the two-app split does.
⚠️Warning
Five consumer features stop working on August 18, 2026. Microsoft is retiring Group Chats, AI-generated podcasts, Copilot Labs, Deep Research, and Mico (the animated assistant character). Two of these need action before the date: podcast episodes must be downloaded individually from your library to be kept, and group chat threads, messages and images will not carry forward — copy anything you want into a document first. Paying business users get Researcher as the replacement for Deep Research; free users get no direct equivalent. Files generated by the standalone app migrate to OneDrive, and Microsoft warns other features may temporarily disappear during the transition.
Microsoft's framing, via EVP Jacob Andreou, is that the app had to earn "the right to exist" by dropping underperforming features. The plainer read is that running a separate consumer app and a business app made Copilot harder to position against single-app competitors — ChatGPT, Claude and Gemini each present one product to both audiences.
💡Key Concept
Why the distinction still matters: even inside one app, the free tier and the M365 tier are meaningfully different products. The free experience competes with ChatGPT and Claude as a general-purpose assistant. Microsoft 365 Copilot is grounded in your organization's documents, emails and meeting history via Microsoft Graph. Shared branding and now a shared app do not make them the same capability — what you get still depends on which licence your account carries.

Core Features
Free Copilot — Everyday AI
The free Copilot chatbot at copilot.microsoft.com offers:
- Web search with citations — every factual answer links to sources by default; built-in grounding against hallucination
- Image generation — DALL-E integration for generating images from text prompts directly in the chat
- Document and image upload — analyze uploaded PDFs, Word docs, images, and data files
- Notebook mode — extended context for longer, more complex tasks
- Voice — speak to Copilot and receive spoken responses
Microsoft 365 Copilot — Enterprise Productivity
M365 Copilot embeds AI into the core Office apps:
- Word: Draft documents, rewrite paragraphs, summarize long documents, suggest edits
- Excel: Generate formulas from plain language, create charts, analyze data, highlight trends
- PowerPoint: Create slide decks from a prompt or document, reformat existing presentations, generate speaker notes
- Outlook: Summarize email threads, draft replies, schedule meeting follow-ups, manage inbox priorities
- Teams: Transcribe and summarize meetings in real time, catch up on missed meetings, generate action items
- Microsoft 365 Chat (BizChat): A cross-app AI assistant that can query across your emails, documents, meetings, and chats simultaneously
Copilot in Windows
Available in Windows 11 via the taskbar button or Win + C shortcut. Useful for:
- Adjusting system settings via natural language
- Answering questions without switching to a browser
- Summarizing open documents or clipboard content
Edge Integration
Copilot is built into Microsoft Edge's sidebar (click the Copilot icon or press Ctrl + Shift + .). Useful for:
- Summarizing the current webpage
- Generating answers based on page content
- Comparing products across shopping pages
Strengths
- Ubiquitous availability: Pre-installed on Windows 11, embedded in Edge, and freely accessible — Copilot has the widest distribution of any AI assistant
- Grounded web search by default: Unlike ChatGPT or Claude, the free Copilot cites web sources for factual queries without requiring a specific mode or tool
- Microsoft 365 deep integration: For organizations already on M365, Copilot has direct access to emails, documents, meetings, and Teams history — no data export or pasting required
- Image generation included free: DALL-E image generation in the free tier is a notable advantage over some competing free AI tools
- Multi-modal: Handles text, images, documents, and voice in the same interface
Limitations & Considerations
- M365 Copilot price barrier: At $30/user/month on top of an existing M365 subscription, M365 Copilot is a significant budget item — most valuable when the organization already has heavy Microsoft 365 usage. Note: Microsoft has announced an M365 pricing increase effective July 2026
- Less customizable than ChatGPT: No equivalent of Custom GPTs or the GPT Store; less community ecosystem
- Copilot Pro vs. M365 Copilot confusion: The Copilot Pro plan ($20/month) adds M365 features for personal/family plans — but not for business; the full enterprise M365 Copilot requires the separate add-on license
- Brand fragmentation: "Copilot" appears in many contexts (GitHub Copilot, Copilot+ PCs, Edge Copilot, M365 Copilot) — they share a name but are separate products with different capabilities and pricing
- Prompt injection is a recurring, unsolved exposure: deep integration into mail, files and calendar is the product's main advantage and also its main risk, because anything Copilot can reach is reachable by an attacker who can plant instructions where Copilot will read them. Three distinct vectors were disclosed in 2026 alone, and Microsoft patched each individually rather than closing the class
⚠️Warning
The August 2026 disclosure is worth understanding as a pattern, not an incident. Varonis Threat Labs repeatedly asked Copilot why auto-execution would not work, and Copilot answered — naming the disabled parameters and one undocumented one, autorun=1. Appended to a crafted query string, that produced a zero-click attack: the victim clicks a link, Copilot loads in their already-authenticated session, and the attacker's instructions run with no prompt and no visible indication. Reachable data included mail, calendar, chat history, connected drives and Copilot's stored memory. Microsoft planned a patch and a formal vulnerability identifier for August 18, 2026.
Two things generalize beyond this bug. First, the assistant disclosed its own attack surface — model output about a system's internals is itself a disclosure channel, which no input filter addresses. Second, the blast radius equals the connected-app list, so the security question to ask before enabling a connector is not whether the assistant is trustworthy but what an attacker inherits if a single link is clicked. This is a live constraint for regulated environments, not a theoretical one.

Getting Started
- Go to copilot.microsoft.com — sign in with a free Microsoft account or use it without signing in
- On Windows 11: click the Copilot icon in the taskbar or press
Win + C - In Edge: click the Copilot icon in the top-right sidebar or press
Ctrl + Shift + . - Try a web search query and notice how Copilot cites sources for every factual claim
- Try image generation — type "create an image of..." and see DALL-E respond in-chat
- If you're an M365 user at work, ask your IT admin whether your organization has M365 Copilot licenses enabled
Key Takeaways
- There are two meaningfully different Microsoft Copilot products — the free general chatbot and the paid enterprise Microsoft 365 Copilot — and from mid-August 2026 they share one app across personal and work accounts. The app merged; the licensing tiers did not, so what you get still depends on your licence
- Five consumer features retire on August 18, 2026: Group Chats, AI-generated podcasts, Copilot Labs, Deep Research, and the Mico character. Download podcast episodes and copy group-chat content out before that date — neither carries forward. Business users get Researcher in place of Deep Research
- The free Copilot is one of the best zero-cost AI options available — web-grounded answers with citations and image generation without a subscription
- Microsoft 365 Copilot is among the most powerful productivity AI tools when the organization already runs on M365 — it queries across your real documents, emails, and meeting history
- Copilot's biggest structural advantage is distribution: it is pre-installed on Windows 11 PCs and available in Edge, making it the most accessible AI assistant for most Windows users globally
- GitHub Copilot (the AI coding tool) is a separate product — see Section 9.6 (GitHub & Version Control) for coverage of GitHub Copilot specifically
