Best AI Search Engines: 8 AI Search and Research Tools

AI search engines that answer with citations, plus research tools that search academic papers or answer only from your sources. Sources, accuracy and availability compared.

How to choose

  • For English sources use Perplexity or Felo; for Chinese sources use Metaso, Nano AI Search or Zhihu Zhida.
  • For academic questions, Consensus and Elicit search only the research literature.
  • AI search can cite weak sources too — open the originals for anything important.
