The answer is a Yes. If you install a free IRC Client software on your system, you can use it to chat for absolutely free. We have already listed some free IRC client software above in this article. There are some paid IRC clients also available that provide a free trial (say 15 days or a month) to use those tools. But, if you get a free IRC client which satisfies your requirements, then it is obvious that you should use such a tool instead of a trial or paid tool.
