Perplexity

An AI search engine that cites its sources

The verdict

Where ChatGPT and Claude are built for chatting and writing, Perplexity is built for looking things up, and every answer lists the web sources it came from so you can check them. Follow-up questions stay in one thread, you can ask by voice, and anything useful saves to a library. The free plan covers everyday questions; Pro at $20 a month adds Deep Research and newer models that most casual users never need.
