How Client-Side Keyword Density Analysis Works
Keyword Density & Frequency Analyzer runs entirely in your browser with JavaScript. There is no sign-up, and whatever you type or open here is processed on your device instead of being sent to a server.
Analyze Content Keyword Density Without Uploading Drafts
Evaluate word frequencies, two-word phrases, and three-word N-grams to prevent keyword stuffing and optimize organic rankings. Paste articles or blog drafts, or attach a .txt, .md or .html file, for instant client-side analysis in your browser memory, keeping unpublished manuscripts private. The table lists the 25 most frequent words or phrases.
Multi-Language and Global Script Support
Our text tokenization engine supports international languages including Spanish, French, German, Arabic, Hindi, Cyrillic, and Urdu. Word boundaries and apostrophes are processed cleanly without dropping contractions or non-Latin alphabets. Languages written without spaces between words, such as Chinese, Japanese and Thai, are not split into separate words, so their counts are not meaningful.
Automatic Tag and Script Stripping for HTML Files
Attach a saved .html page with the Attach File button and the analyzer removes tags, the <head>, <style> and <script> blocks so the counts reflect only the visible text; HTML pasted into the box is counted as typed, tags included.
Why processing in your browser matters
Many online tools upload your files or text to a server to process them. This one does the work on your computer or phone, so your data is not sent to us or stored anywhere else. That lowers the risk when you work with confidential material, although you should still follow your organisation's own rules. Read how this works in our Privacy Policy.
- No uploads: files are opened and saved on your device, so there is no upload or download wait.
- No account: nothing to sign up for or install.
- Free to use: no subscriptions or paywalls.
