Our Verdict
Perplexity AI is the clear winner for general research -- its combination of real-time search and inline citations makes it the most trustworthy AI research tool available. For academic research specifically, pair Consensus or Elicit with Claude's document analysis capabilities. Google Gemini's Deep Research feature is impressive but less consistent in citation quality.
