FAQ
Can AI tools replace Google Scholar? Not entirely, but tools like Semantic Scholar and Consensus offer better AI-powered features like relevance ranking, automatic summarization, and consensus analysis across studies. Most researchers use them alongside Google Scholar.
Are AI research tools reliable for citations? Consensus and Elicit search actual academic databases and link directly to papers. Perplexity cites its sources but may include non-academic results. Always verify citations before including them in academic work.
Which AI tool is best for literature reviews? Elicit is specifically designed for systematic literature reviews. Claude can help synthesize findings across papers once you have collected them.
