What is text analysis, and why use it?

Text analysis turns a piece of writing into numbers you can act on. It shows whether your sentences are too long, whether the vocabulary is varied enough, which words you lean on and how hard the text is for a reader to follow. Writers, students, editors and teachers use it to check a draft before publishing, to match a reading level, or to compare two versions of the same text.

How Text Analysis Works

The analyzer reads your text once and calculates every measure from the same counts, so the results are consistent and instant. Nothing is estimated by a remote service.

1. Split the text

Your text is divided into sentences and words. Abbreviations such as Dr. and e.g., decimals and line breaks are handled so sentences are counted correctly.

2. Measure each word

Every word is counted, its syllables are estimated and its type is checked, so the tool knows how long, complex and common each word is.

3. Work out the statistics

The counts feed the readability formulas, vocabulary measures, sentence statistics, word frequencies and repetition checks, all in a fraction of a second.

Readability Scoring Explained

Flesch Reading Ease

A score from 0 to 100 where higher means easier. Around 60 to 70 is plain English that most adults follow easily, and below 30 is very difficult text.

Flesch-Kincaid Grade Level

The same inputs expressed as a US school grade. A score of 8 means an eighth grader should understand the text. Most web content works best between grades 6 and 9.

Gunning Fog Index

Estimates the years of schooling needed to follow the text on a first read. It leans on the share of complex words, those with three or more syllables.

SMOG Index

Counts words with three or more syllables across the sentences. It is designed for samples of 30 sentences or more, so treat shorter texts as a rough guide.

Lexical Density and Vocabulary Richness

Lexical density is the share of content words, the ones that carry meaning, compared with small connecting words such as the, and and of. A higher figure means denser, more informative writing. Vocabulary richness looks at variety instead. The tool counts unique words, calculates the type-token ratio (unique words divided by total words) and shows how many words are used only once. Together they show whether a text is varied or leans on the same few words.

Word Frequency Analysis

A word frequency list ranks the words in your text from most to least used, with counts and percentages. It helps you spot the main topics of a text, find words you overuse and check keyword usage. Common words such as the and of are hidden by default so the useful words stand out, and you can turn that off to see everything. The repetition panel also finds repeated phrases, words that echo within a few words of each other, and sentences that start the same way.

Your Text Stays on Your Device

Everything on this page runs in your browser. Your text is never uploaded, logged or stored, which makes it safe for drafts, essays, contracts and anything else you'd rather keep to yourself. It's also fast, because there's no waiting on a server, and it keeps working even if your connection drops after the page has loaded.

Works on Mobile and Desktop

The analyzer works in any modern browser on phones, tablets and computers, with nothing to install. On a large screen the results sit in clear panels that you can collapse. On a phone the panels stack and every button is sized for touch.

Frequently Asked Questions

What does a text statistics analyzer do?
It measures what is inside your writing, beyond a simple word count. It scores how easy the text is to read, shows how varied the vocabulary is, ranks the most used words, measures sentence lengths and flags repeated words and phrases.
How is this different from a word counter?
A word counter tells you how long a text is. The analyzer tells you what kind of text it is: how hard it is to read, how rich the vocabulary is, which words dominate and where you repeat yourself. For a quick count of words and characters, use the Word Counter.
Is my text uploaded anywhere?
No. The analysis runs in your browser, on your own device. Your text is never uploaded, logged or stored, so it is safe to use with drafts, essays and private documents.
What is a good readability score?
It depends on your readers. For general web content, a Flesch Reading Ease of 60 to 70 and a grade level of 7 to 9 is a common target. Technical, legal or academic writing scores lower, and that can be fine if your audience expects it.
What is lexical density, and what is a typical value?
Lexical density is the share of words that carry meaning, such as nouns, verbs and adjectives, compared with small connecting words like the, and and of. Written text is often around 50 to 60 percent, and casual speech is lower.
Why does the type-token ratio change with text length?
The longer a text is, the more often common words repeat, so the ratio of unique words falls. Compare it only between texts of similar length. The root type-token ratio shown beside it is less sensitive to length.
Does it work in other languages?
Word counts, sentence lengths, word frequency and character types work in any language that separates words with spaces. The readability formulas and the common-word list are designed for English, so scores for other languages are not meaningful.
