Perplexity AI
perplexity.ai
An AI-powered answer engine that searches the web in real time and returns sourced, cited responses rather than a list of links.
Why it is useful
The most practically useful AI search tool available — it cites its sources inline with every claim, making it far easier to verify answers than with standard AI chat. The real-time web access means it handles current events and recent information that knowledge-cutoff models cannot. For research, quick fact-checking, and replacing multi-tab search sessions, it outperforms most alternatives.
