Cleanor Labs
These sections explain the job in plain language and set expectations for what the tool should do well.
To use the editor, type your Markdown directly or paste an existing block into the input pane. The preview pane renders the result instantly using GitHub-flavored Markdown, so you can confirm headings, links, tables, and code blocks look right as you write.
When you are done, copy the source to your clipboard or download it as a .md file. The editor keeps the focus on the core writing loop, write, check the rendering, keep moving, rather than trying to be a full IDE with plugins and themes.
Everything stays local in your browser. Your content is never uploaded to a server, so the editor is safe for private notes, drafts, and documentation.
GitHub-flavored Markdown (GFM) extends standard Markdown with features that documentation and READMEs rely on. This editor supports GFM tables, task lists, fenced code blocks, strikethrough, and autolinks, so the preview matches how your content will look on GitHub.
That makes it a practical place to draft README sections, issue and pull request text, changelog entries, or any docs you plan to publish on a platform that uses GFM. What you see in the preview is what you can paste into those tools.
Because the same local rendering powers the preview, you get a reliable check of your formatting without ever sending the content anywhere.
