What This Tool Does
Paste or type text and every statistic updates as you go: words, characters with and without spaces, sentences, paragraphs, lines, unique words, reading time and speaking time. Alongside those sit readability scores, a keyword density table, a sentence-length distribution, character-limit meters for the places short copy gets truncated, and a writing goal with a progress bar.
Everything runs inside your browser tab. Your text is never uploaded.
How to Use It
Type directly into the editor, paste from anywhere, or load a .txt, .md, .docx or .pdf file. The headline counts appear immediately in the panel beside the editor.
Set a target in the Writing goal panel to get a progress bar and a running "to go" figure. Add the platforms you publish to in the Character limits panel and watch the meters as you trim. Switch the keyword table between single words, two-word phrases and three-word phrases, and hide common words to see what your text is actually about.
Sentences of 26 words or more are tinted amber directly in the editor; sentences of 40 or more get a stronger tint. This is the part most counters skip: knowing that your longest sentence runs to 62 words is only useful if you can see which sentence it is.
Need to change how the text is capitalized rather than measure it? The Case Converter shows fourteen cases of the same text at once.
Need to tidy the list itself — sort it, drop duplicates, strip blank lines? Line Tools does all of that in one pass.
Why Vietnamese Counts Differently
Vietnamese writes every syllable as a separate space-delimited unit. Split on spaces and you have counted syllables, not words — the word học sinh (student) is one word occupying two syllables. Most Vietnamese words are in fact multi-syllable, so a space-based count overstates the word total by a wide margin.
That number is still the one you usually want. When a Vietnamese university or newspaper specifies a length, they mean the space-separated count, because that is what every editor reports. So this tool shows exactly that figure — and labels it "syllables", with a note explaining the relationship. The number is useful; calling it something it is not would be careless.
Chinese, Japanese and Korean do not use spaces between words at all, so for those scripts the tool counts characters, which is the conventional unit there.
Which Readability Score To Trust
Six indices are shown for English text, and they disagree with each other on purpose — each weighs sentence length and word complexity differently.
Flesch Reading Ease returns a 0–100 score where higher is easier; general web copy usually aims for 60 or above. Flesch-Kincaid Grade, Gunning Fog, Coleman-Liau, ARI and SMOG all return an approximate US school grade level instead, so a result of 8 means an average eighth-grader should follow it.
Two cautions. First, all six are statistical measures over a body of text: below about 100 words they swing wildly, and the panel labels them as unstable when that is the case. Second, they measure only sentence length, word length and syllable counts. A passage of short words in short sentences that argues something incoherent will score beautifully. Use them to catch prose that has drifted long and dense, not as a verdict on quality.
Character Limits and Where Text Gets Cut
A meta title is generally cut around 60 characters in search results and a meta description around 160. An X post allows 280 characters on a free account. An Instagram bio stops at 150, a caption at 2,200. A LinkedIn post allows 3,000 characters but the feed shows only about 210 before a "see more". A YouTube title is capped at 100. An email subject line is usually clipped near 50 characters on a phone.
These are guides, not guarantees — platforms adjust them, and some vary by account tier. The panel records the date the figures were last checked so you can tell how fresh they are.
