Here's what this free tool does in detail — every feature is built to solve real problems, runs entirely in your browser, and is free forever.
The heading query matches any heading that contains the search text. Searching for Start matches ## Getting Started. The first match is used. Enable Case sensitive for exact casing.
For searching and replacing text across the entire document, use Free Markdown Find & Replace.
With Include subheadings enabled (the default), the extraction continues until the next heading of the same or higher level. A matched ## heading includes all ###, ####, etc. beneath it. Toggle it off to stop at the very next heading of any level.
After extracting, use the Free Markdown Heading Shifter to promote the section to standalone H1 level.
The output label shows the heading level, matched heading text, and line count when found. When no heading matches, a clear 'Not found' status appears. No silent failures.
To audit all headings in the document, use the Free Markdown Headings Extractor.
Headings inside fenced code blocks are ignored during the search. Only real ATX-style headings in the document body are considered. The extracted content preserves any code blocks within the matched section.
For adding anchor IDs to headings after extraction, use the Free Markdown Anchor ID Generator.
Drop a multi-section document into the input. Click Load example for a typical doc with several sections.
Type the heading text or a substring into the query field. The first matching heading is used.
The heading and all content beneath it (including sub-headings) are returned as standalone Markdown.
Pull the Installation or API Reference section from a large README for a separate doc.
Extract individual chapters from a monolithic guide into separate files.
Isolate one section for review or feedback without scrolling through the whole document.
Extract the relevant section from shared lecture notes for focused review.
Pull a specific section to import into a CMS, wiki, or knowledge base.
