What is Deep Researcher?
An AI research assistant built for serious research workflows.
Deep Researcher is an AI-powered research tool that helps students, academics, and professionals turn a research question into a structured, citation-backed report. Unlike a simple chatbot, it is designed for multi-step research: it clarifies your question, discovers relevant sources, synthesizes findings, and presents them in a format you can verify and export.
In our tests, DeepResearcher consistently produced deeper academic coverage than general search assistants. On a medical imaging literature review task, it returned 24 citations with clear section headings, while Perplexity returned 8 web sources and Consensus returned 7 scientific papers. For researchers who need exportable reports, Chinese-language support, and structured synthesis, DeepResearcher is the strongest option we tested.
Academic Depth
20+ citations per report, organized by theme and methodology.
Verified Sources
Every claim links to a source you can open and verify.
Export Ready
Download structured reports as PDF or Word documents.
Real Academic Research Workflow
How researchers use DeepResearcher from question to final report.
Define the Research Question
Start with a broad topic and refine it into a focused, answerable question. DeepResearcher can help narrow the scope based on current literature.
Discover Relevant Sources
The AI scans academic databases, preprints, and trusted web sources to find the most relevant and recent papers.
Generate a Structured Draft
Receive an outline with introductions, methodology themes, key findings, and a reference list—ready for human review.
Verify Citations
Every claim links back to its source. Check the original paper before including the citation in your final work.
