About CountMySentences
Free, private, browser-based text analysis tools — built for writers, students, educators, and SEO professionals who care about their words.
What Is CountMySentences?
CountMySentences is a free online suite of text analysis tools designed to help you write more clearly, measure your content precisely, and understand the structure of your writing. Every tool on this site runs entirely in your browser — your text is never sent to a server, stored in a database, or shared with any third party.
The site currently offers nine free tools: a sentence counter, word counter, character counter, keyword density checker, reading time calculator, paragraph counter, line counter, text case converter, and word frequency counter. All tools work in real time as you type or paste text, with no account required and no usage limits.
Why We Built This
Good writing is precise writing. Whether you are a novelist checking sentence variety, a student verifying an essay word count, an SEO writer optimizing content for readability, or a developer analysing log files, you deserve tools that are fast, reliable, and completely free of friction.
Too many similar tools are buried behind paywalls, forced sign-ups, or cluttered with deceptive designs. CountMySentences was built to be the opposite: open the page, paste your text, get your answer. Nothing more, nothing less.
Our Privacy Commitment
All text processing happens locally in your browser using JavaScript. We do not collect, store, or transmit your text content under any circumstances. You can safely paste confidential manuscripts, business documents, or personal notes without any privacy concerns.
For full details on how we handle data, please read our Privacy Policy.
Who Is Behind CountMySentences?
