Copilot

A Copilot is an AI-driven assistant embedded in software environments to provide users with context-aware suggestions, automations and help. In practice it generates or completes text, code, queries or tasks based on the current context and user instructions, but it does not act fully autonomously without human oversight. Copilots typically combine large language models, context windows and integrations with files or tools, and they have limitations such as possible hallucinations, privacy and licensing concerns that require user verification.

As a developer you open VS Code and Copilot immediately proposes a function based on comments and existing code, including suggested test cases. A marketing student uses a Copilot in a word processor to generate several versions of a product description and then manually edits the best one for tone and accuracy. In a business context a Copilot inside an email client helps summarize a long thread and suggests reply drafts, after which the user reviews and sends the final message.
