How do I choose an AI tool to search for academic papers?
When selecting your tool, first identify if you require API integration for your workflow, as scite and Semantic Scholar provide this, while others do not. Consider your budget; Semantic Scholar, Consensus, and Vicena offer free tiers, while scite requires a monthly payment. If your work requires specific technical features, note that Vicena supports direct workspace-to-computer file transfers. Review subscription policies carefully, especially regarding auto-renewal and refund terms, as scite explicitly states no refunds are available. Finally, check platform compatibility, such as the need for a Chrome extension offered by scite versus a browser-only interface. Match these technical and financial requirements against your specific research needs to determine which platform aligns best with your existing academic workflow.
