Paperguide

Paperguide is an all-in-one AI research assistant covering search across 200M+ papers, literature reviews, PDF chat, citation-grounded writing, and reference management.

Paperguide consolidates the tools scattered across a researcher's workflow into a single platform. It offers AI search across more than 200 million peer-reviewed papers, an AI literature review agent, deep research reports, structured data extraction, chat with PDFs, a citation-grounded AI paper writer, and a native reference manager. The goal is to remove the need to juggle separate apps for finding, synthesizing, and citing literature. Beyond discovery and synthesis, Paperguide adds writing support that generates outlines and drafts with citations, plus built-in checks for AI-generated content and plagiarism. It is frequently cited as one of the more generous free plans in the category, giving access to deep research reports, citation-backed answers, and writing support at no cost, with Plus and Pro tiers for heavier use and collaboration. The platform targets students, academics, and knowledge workers who want an integrated research assistant rather than a point tool. Its breadth is its main selling point, though breadth also means individual features may not be as deep as best-in-class specialists in citation analysis or systematic review.
