Resea AI is a deep research agent designed to operate similarly to a professional PhD researcher or consultant. The core functionality of this AI lies in its ability to independently conduct and complete research-related tasks such as academic research, paper writing, market analysis, and business reports.

Resea AI is a deep research agent platform launched in August 2025 that automates the comprehensive academic research process from literature discovery and synthesis through structured report writing at a depth comparable to a professional PhD researcher or research consultant.
The platform integrates with major academic databases including Google Scholar, PubMed, and arXiv to search across hundreds of millions of papers, synthesize findings, and produce complete research reports, literature reviews, and long-form academic documents with accurate citations and logical sectioning without requiring manual paper-by-paper review.
The platform's research depth sets it apart from general-purpose AI writing tools that summarize individual documents or answer specific questions.
Resea performs multi-source research across its integrated academic databases, cross-references findings, identifies consensus and disagreement across literature, and constructs well-organized academic arguments with properly formatted citations.
It supports multiple citation styles including APA, MLA, Chicago, and others, and maintains accurate source indexing throughout even very long documents a capability that becomes critical when handling reports that cite dozens or hundreds of sources.
One of Resea's most technically notable capabilities is its handling of output length. The platform imposes no word limit on generated documents, with verified capability to produce academic reports of 50,000 words or more with maintained logical structure, consistent argumentation, and accurate citations throughout.
This long-document capability is particularly relevant for dissertation assistance, comprehensive literature reviews, systematic reviews, and technical research reports where the required depth cannot be compressed into a shorter format without sacrificing coverage or analytical rigor.
Resea AI's writing editor provides full document editing capabilities for post-generation refinement: paraphrasing, rewriting, summarizing, and expanding specific sections through AI-assisted editing that maintains the document's academic tone and citation accuracy.
