Word counter, case converter and readability checker
Paste once and every tool reads the same text: real character counts, twelve case formats, readability scores, keyword density and SEO title width measured in pixels. Everything runs in your browser — nothing is uploaded.

Counts
Why these four numbers differ
Your text contains emoji, accents or a script where one visible character is built from several code points. Pick the measure that matches where the text is going.
Time to read
230 is the average adult reading speed for familiar prose.
Longest sentences
| Sentence | Words |
|---|
No sentence is longer than {limit} words.
AP capitalises prepositions of four letters or more. Chicago lowercases them all.
All twelve formats
URL slug
Leave this off to keep Hindi, Arabic and accented letters, which are valid in URLs and readable to the people searching for them.
Readability
Six published formulas over the same text. They disagree by two or three grade levels, so all six are shown rather than one being passed off as the score.
Consensus grade
| Formula | Score |

Keyword density
| Phrase | Count | Density |

Add more text to see which phrases repeat.
SEO title and description width
Google truncates by pixel width, not character count. Two 60-character titles can differ by 300 pixels.
Result preview
Cut where Google would cut it. Google also rewrites titles for roughly 60% of results, so treat this as the best case.
Cleanup
Applied in a fixed order, so the same selection always gives the same result.

Questions
Is my text uploaded anywhere?
No. This is a static page with no backend. Every count, conversion and score is computed in your browser by JavaScript running on your own machine, and the text is never sent anywhere. You can disconnect from the network and it still works.
Why does the character count differ from my other tool?
Because "character" has several meanings. Most tools report UTF-16 code units, which counts a family emoji as nine. This one reports what a reader sees by default and shows all four measures — graphemes, code points, UTF-16 units and UTF-8 bytes — whenever they differ.
Does Title Case follow a style guide?
Yes, and you can choose. AP and Chicago both lowercase articles, coordinating conjunctions and short prepositions, but differ on longer prepositions — AP capitalises "Over", Chicago does not. Both always capitalise the first and last word.
How accurate are the readability scores?
They are accurate arithmetic over a syllable heuristic, which is the best any of these formulas has ever had. They detect long sentences and long words reliably and cannot judge whether your writing is good. They apply to English only, so the tool refuses to score other scripts rather than returning a flattering number.
Why measure SEO titles in pixels?
Because that is how Google truncates them. Two titles of exactly 60 characters can differ by over 300 pixels depending on which letters they use, so a character limit is a rough average rather than a rule.
Is my text saved between visits?
Your text and preferences are saved in this browser's localStorage, on your own device, so the page is as you left it when you come back. Nothing is sent to a server. Use "Reset everything" in the footer to clear it.
Your text never leaves this tab. There is no server to send it to: this is a static page, and every calculation happens in your browser.
