Which tool for an AI search engine?

AI search engines answer the question instead of handing you ten links. What matters is whether every claim has a source you can open, how fresh the results are and what you can do with the answer next.

Perplexity is the best AI search engine, with a cited source on every claim. ChatGPT is best when you want search inside a full assistant, Gemini for Google users, and Grok for real-time news from X.
