What it is

Cluster Army Keyword Clusterizer turns a list of terms into keyword groups for organizing related phrases and examining search intent in SEO content work. It calculates distributions for stems, individual words, pairs, and triples, then connects each starting keyword with frequently associated terms. Enter terms by pasting text or uploading a.txt file, with one word or phrase per line. Text input can contain up to 50,000 rows, and uploads are limited to 2 MB. English and Italian settings can exclude standard stopwords; users can also add words to exclude from single-key associations. Results include a chart for each distribution and a mind map with expand, collapse, and download controls. Five downloadable files cover stems, individual terms, pairs, triples, and full clusters, but remain available for 10 minutes after processing. Lists made with Cluster Army’s Long Tail Generator can be imported with one click. The web tool is free: free.
