Text Analysis Tools
Measure, compare, and shape your text instead of just transforming it — count words, sentences, and characters live as you type, check a post against the X, Instagram, or SMS limit, see which words repeat, spot exactly what changed between two versions, or turn a title into a clean URL slug.
Everything else on this site changes your text — a case tool rewrites capitalization, a cleanup tool strips something out. These tools do the opposite: they measure, compare, or reshape without editing your actual writing. The Word Counter reads text back to you as numbers (word count, character count, reading time), and the Slug Generator turns a title into a different, URL-safe form without touching what the title actually says.
The Word Counter and Slug Generator both solve problems that show up right before something gets published. A student needs to know if an essay clears a word minimum before submitting it. A social media manager needs to know if a caption fits under a platform's character limit before posting it. A blogger or developer needs a clean, consistent URL for a new page without hand-typing it and risking a stray capital letter or space.
The Sentence Counter and the Twitter/X Character Counter narrow the same idea down. The first looks at the shape of your writing rather than its size: how many sentences there are, how long the average one runs, and which one is the longest, with every sentence listed so you can check the splits. The second checks a draft against one limit at a time (X, an Instagram caption, or a single SMS) with a live meter that follows X's rules for links and emoji.
They're also often used back to back on the same piece of text: check a title's length with the Word Counter, then generate its slug with the Slug Generator — two quick, read-only checks before you hit publish.
The Word Frequency Counter and Duplicate Word Finder look at which words you lean on: the first ranks every word by how often it appears, with percentages and optional stop-word filtering, and the second flags accidental repeats like "the the" or lists every word used more than once — handy for tightening an essay or finding keyword overuse.
The Text Compare Tool answers a different question: not "how long is this?" but "what changed?" Paste two versions of a draft, a code snippet, or a pasted paragraph and it highlights every added and removed line, word, or character — without altering either version.

What's the difference between the Word Counter and the Slug Generator?
They measure and transform, respectively. The Word Counter tells you facts about text you already have — how many words, characters, or sentences it contains, and whether it fits a platform's character limit. The Slug Generator changes text into something new — a title becomes a clean, URL-safe string. Neither one edits your writing itself; that's what the Case and Cleanup tools are for.
Can I check a title's length and turn it into a URL in the same pass?
Yes, and that's a common combination when publishing something. Paste your title into the Word Counter first to confirm it fits your target length (a meta description limit, a social caption limit), then paste the same title into the Slug Generator to get the URL-ready version — both read-only checks, so running one doesn't affect the other.
Which counter should I use: Word Counter, Sentence Counter, or the Twitter/X Character Counter?
Pick by the question you are asking. The Word Counter gives you overall totals (words, characters, paragraphs, reading time). The Sentence Counter is about structure: how many sentences, how long they run, and which ones are the longest and shortest. The Twitter/X Character Counter checks one draft against one platform's limit, with X's weighting for links and emoji. They read the same text, so you can paste it into all three.
Do these tools track or store anything about the text I analyze?
No. Every tool in this category runs entirely in your browser — counting words, generating a slug, or comparing two texts is plain JavaScript running on your device, with nothing sent to a server and nothing saved once you close the tab.
Which tool should I use before publishing a blog post or product page?
Both, for different parts of the page. Run your meta description through the Word Counter to make sure it fits Google's typical display length, and run your title through the Slug Generator to get a clean URL — checking length and generating the URL are two separate steps, not one tool doing both.
