Count every word in real time.
Words, characters, sentences, paragraphs, reading time, Flesch-Kincaid readability, keyword density, and character limits for every social platform. Updates as you type.
Beyond just counting words.
Word count is the floor. What you really want to know: will it read fast, will it fit where you are publishing, and what is it actually about. Here is how each metric in the panel is calculated and what to do with it.
Words Count
= text.split(/\s+/).filter(non-empty).length
Whitespace-separated tokens. Works for most Western languages. Undercounts for Chinese, Japanese, and Korean text (no spaces between words). For CJK content, use the character count.
Characters Count
With spaces vs without spaces
Two values: total chars (what social platforms count, what Twitter limits at 280) and chars without spaces (what some academic submissions count). Both include punctuation and emoji.
Reading time Time
= words ÷ 250 wpm
250 words per minute is the median adult reading speed for general non-fiction (Iowa State 2019 reading-rate study, Nielsen Norman data). Technical content slows to ~180 wpm; casual blogs read faster at ~300.
Speaking time Time
= words ÷ 130 wpm
130 wpm is the average TED talk pace and a comfortable pace for a podcast or webinar. Conversational pace runs ~150 wpm; auctioneers hit 250+. Use for estimating talk length and script timing.
Flesch-Kincaid Readability
FRES = 206.835 − 1.015 × (W/S) − 84.6 × (Sy/W)
Reading-ease score 0-100. 60-70 is the sweet spot for general adult readers (around 8th-9th grade). Hemingway scores ~80. Academic papers score 30-50. Lower = harder to read. Used by the US Navy since 1975.
Keyword density Content
word count ÷ total words × 100, stopwords excluded
How often each meaningful word appears as a percent. Useful as a "what is this actually about" sanity check. Not an SEO ranking factor since the early 2000s. Aim for 1-3% on your primary keyword; higher reads as stuffed.

Honest answers.
Word count divided by 250 words per minute, the median adult reading speed for general non-fiction (Nielsen Norman + Iowa State 2019 reading-rate study). Technical content slows to ~180 wpm; casual blog posts read at ~300 wpm. Speaking time is calculated at 130 wpm, the average TED talk pace.
Flesch Reading Ease scores text on a 0-100 scale where higher is easier. 60-70 is the sweet spot for general adult audiences (around 8th-9th grade reading level). Hemingway, Stephen King, and most newspapers score 70-80. Academic papers usually score 30-50. Below 30 is hard to read. Above 80 starts feeling oversimplified for an adult audience. Grade level is the equivalent US school grade required to understand the text.
How often each word appears as a percentage of total words. Useful as a sanity check to see what your content is actually about, not as an SEO target. Google has not used keyword density as a ranking factor since the early 2000s. Aim for a 1-3% density on your primary keyword and stopwords (the, and, of) are excluded so you see what is meaningful.
X (Twitter): 280 characters per post, 25,000 for X Premium. Instagram caption: 2,200 characters but first 125 are shown without "more" tap. LinkedIn post: 3,000 characters but first ~210 shown before the truncation. Facebook post: 63,206 characters, but engagement drops sharply past 80. Meta description (Google): 150-160 characters before truncation. Title tag: 50-60 characters.
Character counts include all characters including emojis (which count as 1-2 each depending on whether they are composed). Word counts use whitespace-separated tokens, which works for most Western languages but undercounts for Chinese, Japanese, and Korean text that does not use spaces between words. For CJK content, the character count is the more useful number.
