Stop concatenating Markdown by hand
Combining Markdown files looks easy until you actually do it: heading levels collide, internal links break, frontmatter conflicts, code fences get accidentally nested. Our Markdown merger handles it for you. Drop the files in the order you want, and we produce a single, coherent document.
Use it to assemble chapter files into a book, combine notes for an AI summarization run, or build a single-file documentation export from a multi-file repo.
What the merger does
- Reorders files by drag-and-drop
- Adds an optional separator between sections
- Promotes or demotes heading levels to keep a coherent hierarchy
- Rewrites internal links so they resolve in the merged file
- Merges or strips conflicting frontmatter blocks
- Generates a top-level table of contents
The output is a single .md file ready to be fed to an AI, exported to PDF, or published as a single-page doc.
