Microsoft Copilot

Microsoft Copilot is the AI layer Microsoft has built across its entire product portfolio, powered by OpenAI’s GPT-4 models. For consumers, the most significant fact is simple: the free Copilot web app and Windows integration give you access to GPT-4-level responses without paying anything, which makes it one of the best free AI options available.

The Copilot web experience at copilot.microsoft.com supports text chat, image generation via DALL-E 3, and web-grounded answers through Bing — all for free. It’s built into Windows 11 as a system-level assistant and lives in the Edge sidebar, so for Windows users it’s always one click away.

The enterprise story is different and more powerful. Microsoft 365 Copilot ($30/user/month, requires M365 Business) embeds AI into every Office app: in Word, it drafts documents and rewrites sections. In Outlook, it summarizes email threads and drafts replies. In Excel, it generates formulas, creates pivot tables, and analyzes trends in plain English. In Teams, it writes meeting summaries and action items in real time. In PowerPoint, it builds presentations from a Word document or a text prompt.

The depth of M365 Copilot’s integration is unmatched — it has access to your organization’s emails, documents, calendar, chats, and meetings, and can reason across all of them together. This makes it the most contextually aware AI for knowledge workers living inside Microsoft’s ecosystem.

The main friction is cost: $30/user/month on top of existing M365 subscriptions is significant for large teams. But for organizations that are deeply Microsoft-centric, the productivity returns can justify the investment quickly.
