Best AI Tools for a Literature Review in 2026

A 2026 guide argues that AI tools for literature reviews aren’t interchangeable: different platforms specialize in discovery, screening and extraction, or citation verification. The piece says the right workflow typically combines tools while keeping key decisions under human control. It evaluates products using five criteria—discovery coverage, fit for review workflows, source traceability, human-review controls, and free access—rather than lab benchmarks, and advises checking current capabilities and prices for major projects. For early research, it highlights Canyam’s unified discovery. For structured systematic reviews, it recommends Elicit for screening and data extraction. Consensus is positioned for fast, cited yes-or-no answers, while Scite checks citation context using supporting or contrasting labels. Semantic Scholar is presented as a free search option covering more than 200 million papers.
