AI for Deep Research (2026)

Deep research used to mean opening 30 tabs and writing a Notion doc nobody read. AI deep research tools now plan multi-step research workflows, pull from primary sources with citations, and synthesize findings into structured outputs in minutes rather than days. Claude and Perplexity lead general-purpose deep research with web-grounded citations; Elicit and SciSpace specialize in academic literature with paper-level citation tracking; Julius AI handles deep research on tabular and code-grounded data analysis.
