FAQ
What is the best AI tool for research?
There is no single best tool. Discovery platforms help find papers, citation tools help evaluate how claims are received, and reading assistants help summarize dense sources. Use several where they complement your method.
Can AI research tools replace a literature review?
No. They can speed up discovery and screening, but researchers still need a defined search strategy, source verification and critical reading. Check database coverage, citation accuracy and how summaries handle conflicting evidence.
How should researchers verify AI-generated findings and citations?
Open the original paper and confirm every cited claim, publication detail and quotation. AI summaries can omit context or merge sources, so primary literature remains the authority.
