Frequently Asked Questions
Can AI research tools replace Google for everyday lookups?
For many queries, yes. Perplexity and Gemini are faster than reading through Google search results because they synthesize information directly. However, Google is still better for finding specific websites, local businesses, and highly current breaking news.
How do I verify AI research tool citations?
Always click through to the original source and confirm the AI's summary matches what the source actually says. Perplexity makes this easy with inline citation links. Budget 30 seconds per key claim to verify, especially for important decisions or published work.
Are AI research tools good enough for academic papers?
AI tools are excellent for literature discovery and initial synthesis but should not be your only research method. Use Elicit or Consensus to find relevant papers, then read the key papers yourself. Never cite a paper based solely on an AI summary without reading the original.
