Headings, bold, italic, inline code, links, unordered lists, blockquotes and fenced code blocks. Tables, ordered lists, images, footnotes, task lists, strikethrough and raw HTML are not parsed. A fence renders as plain escaped code, even when it starts with js or bash.
No. The page has Write and Preview tabs. The preview updates from the current draft when you switch tabs, but you cannot see both panes side by side. Copy HTML places the generated markup on the clipboard.
No. Fenced code keeps line breaks and escapes angle brackets, but no language parser runs. A language tag such as js stays visible inside the block rather than activating JavaScript colors.
Raw HTML is escaped before preview, so tags appear as text instead of executing. Links are limited to http, https and mailto; other schemes become #. The preview link opens in a new tab with noopener and noreferrer.
The editor stops accepting Markdown at 500 KB and shows an error while truncating the pasted value. That guard keeps rendering responsive. There is no save, history or account, and closing the page clears the draft.
Yes. Copy HTML puts the generated fragment on the clipboard. Paste it into a Text or Code editor, then check the theme styles because the preview uses the app's own typography. Recheck tables and images elsewhere since this parser does not create them.
Compose Markdown with a tabbed preview covering headings, emphasis, links, lists, blockquotes and fenced code for READMEs, posts and notes. Input hash Title and dash bullets witnessing formatted hierarchy. Reference table maps tokens: hash Title equals H1 | double hash equals H2 | dash equals bullets | double asterisks equal bold | triple ticks equal a plain code block. Example one drafts README: title, installation bullets and a fenced code block. Edge handling escapes embedded HTML, leaves an unclosed fence as literal backticks and has no table parser. Developers scaffold docs, bloggers outline articles and students structure notes systematically.
Markup translates predictably: headings structure sections, bold and italic emphasize, inline code marks tokens, fenced blocks preserve whitespace, links connect resources, blockquotes cite sources and unordered lists group items. A fenced block keeps indentation and escapes markup, but every fence renders as plain code because there is no syntax highlighter. Example two builds a tutorial: hash Title, dash setup steps, a fenced command block and exported HTML pasted into WordPress Text mode. Edge cases: nested lists are not parsed as a hierarchy, image syntax is not converted, and raw HTML is escaped before preview. Switch between Write and Preview to catch broken delimiters, validate links and archive sources every revision.
Enter a hash Title, a dash list and a fenced code block, inspect Preview for structure, duplicate HTML for WordPress insertion. The parser excludes tables, ordered lists, images, footnotes, task lists, strikethrough, raw HTML and syntax highlighting. It also has no PDF export or collaborative editing. For word, sentence and reading-time totals complementing documentation length planning, continue with our length counter at /word-counter to gauge scope accurately. The preview also leaves ordered-list numbers as plain paragraph text. Version markdown sources and exported HTML quarterly.
