Distraction-free text editor with auto-save, word count, dark mode, and markdown formatting support.
A bare text area is the whole interface: type, and the note saves itself automatically in the browser, so a closed tab or a crash does not lose your work. A live counter tracks words, characters, and lines as you type, a dark-mode toggle switches the surrounding chrome, and markdown-aware formatting lets you preview headings, lists, and emphasis without leaving the page. The surprise most users hit is that auto-save is local, not cloud. Your note lives only in the browser where you typed it, so another device, a different browser, or a cleared site-data setting will not find it.
A concrete input and expected output from the current implementation.
Input
The quick brown fox jumps over the lazy dog.
Expected output
9 words, 44 characters with spaces (36 without), 1 line, and the text stored exactly as typed.
The sentence has nine whitespace-separated words. Counted exactly as typed, the characters come to 44, including the eight spaces and the final period; excluding the spaces leaves 36 (the letters plus the period). The single line counts as one line.
After a short pause in typing, the current text is written to the browser's storage, and reopening the page restores it. There is no save button and no upload: the note exists only inside the browser where you typed it. That is also the main limitation - the note does not follow you to another device or browser, and clearing the browser's site data deletes it.
The counters recalculate on every change: words split on whitespace, characters count everything as typed, and lines follow your line breaks. Markdown stays as plain text in the editor; the preview mode renders headings, emphasis, lists, and links. What is saved is always the raw markdown, so copying from the editor carries the markup, not the styled result.
Auto-saved text is restored from browser storage when the page loads, so a missing note means that storage was cleared or replaced: private or incognito mode, a site-data or cookie wipe, a browser profile switch, or a storage limit reached. There is no backup anywhere else. For anything you cannot afford to lose, copy it out before relying on the auto-save.
No account and no upload. The editor, counters, and auto-save all run in the browser, and the stored text stays in the browser's own storage for that site. The trade-off: nothing syncs, so the note is not available on your phone or another computer. If you need the text elsewhere, copy it out yourself.
