What is this tool?

A Keyword Density Checker analyzes text and shows how often each term appears — both as a raw count and as a percentage of the total words (its density). It does this for single words and for 2–3-word phrases (n-grams), so you can see which terms and combinations dominate your writing, not just isolated words. An optional stopword filter ignores common words like "the" and "and" so the results focus on meaningful keywords, and you can export the table to CSV or copy it as text for a report. Density is a guide for spotting over-use, not a target to chase — natural, useful writing comes first. For a quick word total, reading time, or a goal bar, pair it with the Word Counter.

How to use this tool?

1. Paste or type your text into the input box. 2. Choose whether to count single words, 2-word phrases, or 3-word phrases. 3. Turn on the stopword filter to ignore common words if you want cleaner results. 4. Read the table of top keywords and phrases with their count and density percentage. 5. Export the results to CSV or copy them as text for your report. 6. Adjust your text and re-check to balance over-used terms.
