Automated keyword grouping (clustering) tools. Do you use any?

Here's Serpstat's recent addition: https://www.searchenginejournal.com/serpstat/206074/
With the description of how it works and what data you get.

Do EU/US SEOs use such tools? I know russian seos do, there are a few similar tools: rush analytics, just magic, content yoda. But it was hard finding SEOs from US who use these.

Which country are you from Russia or US?

Of course dude you will find US SEO to use that the language itself will explain it.
