+
+[ResumeMD](https://resumemd.pro) is a free online Markdown editor purpose-built
+for resumes. Like [Dillinger](/tools/dillinger/), it loads right in your web
+browser, so there's nothing to download or install. The layout is split into two
+panes: the Markdown editor on the left and a live resume preview on the right.
+You can pick one of 32 templates and export the result as a PDF without creating
+an account, and documents are stored locally in your browser by default.
+
+ResumeMD supports GitHub Flavored Markdown through the
+[react-markdown](https://github.com/remarkjs/react-markdown) and
+[remark-gfm](https://github.com/remarkjs/remark-gfm) processors. Because it is a
+resume tool rather than a general-purpose editor, headings carry structural
+meaning: the H1 becomes the resume name, H2s become section headers, and H3s
+become job titles. That focus also explains the gaps in the table below — raw
+HTML, heading IDs, and syntax highlighting are not supported, since none of them
+apply to a resume.
+
+The Markdown editor, all 32 templates, and PDF export are free. A paid tier adds
+DOCX, HTML, and plain text export along with AI-assisted features.
