I needed to solve a specific task. I was looking for a list of keywords for an English language project to come up with associations. I turned to Google and started searching for suitable websites. However, it turned out to be not so easy. Either the websites didn't provide the information I needed, or they required payment upfront, which didn't allow me to test them and understand if it was worth paying. On keys.so, I found a solution. The list of a million words is sorted instantly. I type in the first letters, and frequent words appear, which is very convenient. There are various sorting options, help, and user-friendly filters. Everything is intuitive. And the most important thing for me is the ability to export data in CSV format. I was able to test all of this for free, so now I am confidently ready to pay for the service. I didn't use other features of the site, so I can't comment on them.
