# The Context File: One Page That Makes Every AI Tool Work Better for You

*Every new chat starts with a brilliant stranger. A short, well-kept document about who you are and how you work fixes that across every assistant you use. Here's how to write one.*

Every time you open a new chat with an AI assistant, you meet a brilliant stranger. It knows a startling amount about the world and nothing at all about you: your job, your audience, the words you hate, the format your boss actually reads.

Most people solve this by retyping the same background over and over, a little differently each time. There's a better way, and it fits on one page.

A **context file** is a short document that describes you, your work and your preferences in a form an AI can use. You paste it at the start of a conversation, upload it to a project, or drop it into the custom-instructions setting many assistants now offer. Write it once, keep it current, and every tool you use gets a little less generic.
