Markdown adds visible structure to plain text with everyday symbols. Those signals can make a document easier for people and AI tools to inspect, but they do not guarantee correct interpretation.

What is Markdown?

Markdown in one sentence

Instead of clicking buttons to format text, you type small marks: # for a heading, ** around bold, - for a list. The marks are plain characters, so the file can be opened in ordinary text editors and usually reduces dependence on one app. Markdown extensions and rendering can still vary between tools.

Why it matters for AI

Markdown exposes structure through visible syntax instead of relying on visual styling alone. Headings, list markers, and table delimiters give AI tools useful structural signals and make the input easier for you to inspect. That can reduce ambiguity, but it does not guarantee that a model will interpret every document correctly or produce a better answer.
