markdown-it-title is a plugin for the markdown-it library that extracts the document title and optional excerpt paragraphs during markdown parsing. It's designed for developers working with plain markdown files who need to programmatically extract titles for HTML `<title>` tags, Open Graph metadata, or meta descriptions without using YAML front matter. The plugin supports configurable heading levels for title extraction and can capture multiple paragraphs as excerpts for use in page summaries or post excerpts.
