Questions & Answers

As answered by people managing Paperguide AI and AZIPCODE.

What makes your product unique?

Paperguide AI's answer

Paperguide is an AI Research Platform for Scientific Research Workflows, built specifically for the way real research is done. Unlike generic AI writing tools that hallucinate citations, Paperguide grounds every claim, extraction, and reference in a real, peer-reviewed source paper.

What sets Paperguide apart:

-Unifies the full research workflow in one connected platform. Discovery, screening, extraction, synthesis, writing, and references all run on the same paper library, replacing the typical four to six tool research stack. -AI-native architecture. Every paper saved to the Reference Manager is immediately usable by AI Search, the Literature Review Agent, Research Agent, Chat with PDF, Structured Data Extraction, and the AI Paper Writer. No re-uploading. -Citation grounding at the architecture level. The AI Paper Writer pulls citations only from your real reference library, eliminating fabricated references that plague generic AI writing tools. -Structured workflows for serious research. AI Literature Review runs a five-step Plan, Search, Screen, Extract, Synthesize pipeline. Deep Research Report adds researcher confirmation at every stage. Both are built for multi-week and multi-month research projects. -Built for research teams. Shared libraries, customizable permissions, and review workflows are built in from the ground up, supporting research labs, principal investigators, systematic review teams, and evidence synthesis groups. -200M+ peer-reviewed papers across PubMed, arXiv, OpenAlex, and Semantic Scholar, with paper quality evaluation using SJR, SNIP, and citation metrics on every result.

Why should a person choose your product over its competitors?

Paperguide AI's answer

Paperguide is the only AI research platform that brings the entire scientific research workflow into one connected workspace. Competitors handle one stage well. Elicit handles structured extraction, SciSpace handles paper analysis, NotebookLM synthesizes a defined source set, Consensus answers evidence-meter questions, and Scite verifies citation context. Each of these tools stops at their stage, leaving the researcher to stitch outputs across four to six platforms.

Paperguide runs the connective tissue between every stage on one shared paper library. Researchers find papers across 200M+ peer-reviewed sources from PubMed, arXiv, OpenAlex, and Semantic Scholar, organize them in the Full-fledged AI-native Reference Manager that replaces Zotero, Mendeley, and EndNote, screen and synthesize through the AI Literature Review Agent and Deep Research Report, extract structured evidence into custom-column tables with source-linked citations, chat with PDFs conversationally with page-level rationale, and draft research papers and reviews with the Citation-Grounded AI Paper Writer where every reference is verified against the actual library.

The architecture-level difference is citation grounding. Generic AI writing tools and research assistants hallucinate references that do not exist. Paperguide's AI Paper Writer cites only from your real library, eliminating fabricated references at the architecture level. Combined with paper quality signals (SJR, SNIP, citation metrics) on every result, Paperguide is built for the multi-week and multi-month research projects of research labs, principal investigators, postdocs, systematic review teams, and evidence synthesis groups, where credibility, accuracy, and team collaboration all matter.

How would you describe the primary audience of Paperguide AI? Paperguide is designed for serious scientific research workflows. The platform is built for research labs, principal investigators, postdocs, faculty, systematic review teams, evidence synthesis groups, research librarians, scientific research professionals in industry R&D and clinical research, and research analysts building evidence bases.

Research labs and research groups use Paperguide for multi-week and multi-month literature reviews and evidence syntheses. Principal investigators and research faculty rely on the platform to prepare grant proposals, manuscripts, and grant-grade evidence reviews. PhD researchers and postdoctoral researchers run structured reviews and thesis chapters on it, while systematic review teams use it for Cochrane-style and discipline-specific protocol-driven evidence syntheses. Evidence synthesis teams in health, life sciences, and policy build evidence bases for decisions and publications. Research librarians and methodology supervisors use it to oversee reviews and support research teams. Scientific research professionals in industry R&D and clinical research produce reproducible evidence reports, and research analysts and policy researchers build evidence bases for organizational and policy decisions.

The common thread across this audience is an end-to-end, multi-week or multi-month research process where credibility, citation accuracy, and team collaboration all matter.

What's the story behind your product?

Paperguide AI's answer

Paperguide was built to fix the fragmentation problem in scientific research. A single research project typically runs across four to six disconnected tools: PubMed or Scopus for search, Zotero or EndNote for references, Covidence or Rayyan for screening, Excel or DistillerSR for extraction, and Word or Overleaf for writing. Every handoff loses data and burns hours of non-research work. Paperguide was built to consolidate the entire research workflow into one collaborative AI-native platform where every claim, extraction, and citation traces back to a real, peer-reviewed source paper.

Which are the primary technologies used for building your product?

Paperguide AI's answer

Paperguide is built on a modern AI research stack: evaluated language models for agentic workflows, a custom hybrid semantic and keyword search pipeline across 200M+ peer-reviewed papers (PubMed, arXiv, OpenAlex, Semantic Scholar), vector embeddings and retrieval-augmented generation for citation grounding, paper quality scoring (SJR, SNIP, citation metrics), and a cloud-native collaborative workspace with a Chrome extension and public Search API. Subscription billing is powered by Chargebee.

Who are some of the biggest customers of your product?

Paperguide AI's answer

Paperguide is used by researchers and research teams across leading universities, research labs, and industry R&D organizations worldwide.
