Questions
›Which Markdown does it support?
GitHub Flavored Markdown: headings, lists, links, images, code blocks, tables, task lists, strikethrough and automatic links. Raw HTML works too, though scripts, style sheets and forms are removed from the preview for safety.
›Where is my draft saved?
In your browser's local storage on this device, a moment after you stop typing. It isn't synced anywhere, and clearing your browser data removes it, so download a copy of anything you want to keep.
›What does the HTML download look like?
A single self-contained page with clean, readable styling built in. It works offline, follows your system's light or dark mode and prints neatly. "Copy HTML" gives you just the body markup to paste into a CMS or email.
›Can I turn it into a PDF?
Yes. Download the .md file and open it in our Markdown to PDF tool, or open the downloaded .html page and use your browser's Print → Save as PDF.
›Is my data uploaded anywhere?
No. This tool runs entirely in your browser, and Rounder never sends what you type or drop in to a server, ours or anyone else's. Once the page has loaded, along with any AI model the tool uses, it even works offline.
