Best AI Research Agents of 2026
Research is one of the most time-intensive knowledge tasks, and AI can speed up the reading — but not the checking. This guide compares AI research tools for literature reviews, market analysis, document summarisation and multi-source synthesis on what each documents: the sources it can read, whether it cites them, and how it handles your own files. Whatever the tool, check every citation before you rely on it.
