Markdown Split Editor

live · no libraries

Write markdown on the left, see it rendered on the right — by a small parser written from scratch in this page. Nothing is fetched, nothing is executed: raw HTML is printed as text and unsafe links come out as plain words. Type anywhere and every count updates live.

    Ctrl+B bold · Ctrl+I italic ·
    Ctrl+K link — all with undo intact. The colour in the source pane is a
    second pass of the same parser, painted behind the text box, so typing still behaves exactly
    like a plain one. Both panes are focusable, so arrows and PgDn scroll them, and
    they stay lined up by source line, not by percentage. Words are counted from the rendered text; images render
    as a placeholder chip on purpose — this page makes zero network requests.
