Result
This page has no server side at all. The table you paste is parsed by JavaScript inside your own browser, the chart is drawn on a canvas element on your machine, and the export file is assembled locally. Nothing is uploaded, stored or written to any log. You can disconnect from the network after the page has loaded and everything will still work — which is the simplest way to verify the claim yourself.
Facts and limits of this method
| Counting unit | A word is a run of characters between spaces (a \S+ token) |
|---|---|
| Word length | Counted in characters (code points); punctuation glued to a word counts toward its length |
| Tie-breaking | When lengths are equal, the word that appears first in the text wins |
| Top-5 mode | Shows the five longest words in descending order of length, duplicates included |
| Case | Not changed — each word is shown exactly as written in the text |
| Updates | Recalculated on every change to the text, nothing is sent to a server |
When it misleads you
- Punctuation glued to a word without a space — a comma, period, quote, hyphenated dash — counts toward its length. "Electromagnetic," at the end of a sentence is one character longer than the same word without the comma.
- Strings made of digits, code or a URL ("https://example.com/path") are counted as words too and can "win" purely on length, without being an actual word of the language.
- A hyphen does not split a word ("well-known" is one 10-character word), but an en dash or em dash with spaces on both sides splits the text into two separate words.
- When several words share the maximum length, single-winner mode shows only the first one in reading order — the others of the same length are left out unless top-5 mode is on.
How it is calculated
The text is split into words on spaces and line breaks — the same logic as the character counter. Each word is a continuous run of non-whitespace characters.
Each word's length in characters is measured, then the list is sorted in descending order of length. The longest word becomes the main result.
In top-5 mode, the first five entries of the sorted list are taken — they can include the same word more than once if it appears several times in the text.
The top-5 list is rendered as "word — N characters", one word per line, keeping each word's original case.
Questions and answers
Does punctuation count toward a word's length?
Yes, if it is glued to the word without a space. A comma or period right after a word adds one character to its length.
What if several words share the same maximum length?
Single-winner mode shows only the first one in reading order. Turn on top-5 mode to see the other words of the same or slightly shorter length.
Can a URL or a number end up at the top?
Yes — the tool cannot tell a regular word from a URL, number or code. Any space-free run of characters counts as a word.
How is a hyphenated word's length counted?
A hyphen does not split a word, so "well-known" is counted as one 10-character word, hyphen included.
Is my text sent anywhere?
No. All parsing runs in your browser; the text is never transmitted anywhere.
