Frequently asked questions
Which Markdown flavor does this support?
Standard Markdown syntax via the widely-used "marked" library — headings, emphasis, lists, links, images, code blocks, blockquotes, and tables all render correctly.
Can I use this to write GitHub README files?
Yes — the core syntax matches what GitHub, GitLab, and most Markdown editors support, so you can preview your README or documentation before pasting it in.
Is my Markdown content uploaded anywhere?
No. Parsing and rendering happen entirely in your browser using a local JavaScript library — nothing you type is sent to a server.
