Microsoft Copilot: Complete Guide for Business Use in 2026

Microsoft Copilot is Microsoft's enterprise AI assistant built into the Microsoft 365 suite — Word, Excel, PowerPoint, Outlook, Teams, and SharePoint. Powered by OpenAI's GPT-5 series models, Copilot allows employees to generate documents, analyze data with natural language, summarize meetings, and create presentations, all without leaving the apps they already use.

Teams Meeting Intelligence

Meeting summaries, transcription, and action item extraction — among the best meeting AI in the market.

Excel Natural Language

Generate formulas, analyze data, and create charts by describing what you need in plain English.

PowerPoint Generation

Create entire presentations from Word documents, outlines, or simple text prompts in minutes.
