Scite

Scite is an AI research assistant built on "Smart Citations". For millions of scientific articles, Scite shows not only how many times a paper has been cited, but how: whether later studies support it, contrast it, or simply mention it, with the citing sentence shown in context.

This helps researchers, students and professionals evaluate how reliable a claim is and find the most relevant evidence quickly. Scite Assistant answers research questions with references drawn from real papers, so its answers are grounded in the scientific literature. Researchers can also monitor citations to their own work, check reference lists, and use the browser extension while reading.

Good fit if you: do academic, medical or scientific research and need to check how well-supported a claim is.
Less ideal if you: want casual, general-knowledge answers; a general AI assistant is simpler.

Pricing: free trial; paid individual and institutional plans.
