Also, for regular personal/small user base, free tier is more than enough. And you get a free .ts.net subdomain to use with your apps, if you need that.

The answer is not real. The tool, on the other hand, is called Perplexity. It “understands” your question, searches the web, and gives you a summary, citing all the relevant sources.
