Academic publishing keeps accelerating — and so does the gap between what researchers are expected to read and what they have time for. A typical literature review involves hundreds of PDFs, weeks of reading, and a synthesis that's outdated by submission time.

PapersGPT is an AI research assistant built directly into Zotero. It reads your library, answers questions across your PDFs with cited highlights, and automates the most tedious parts of research — so you can spend your time on the actual science.

Built for the Researcher Workflow

Batch-reading your corpus

Select a collection of 50 papers and run AutoPilot to generate structured summaries overnight: research question, methods, sample, key findings, limitations, relevance to your project. Wake up to a screening-ready reading list.

Cross-paper synthesis that cites its sources

Multi-PDF chat (up to 300 PDFs) lets you ask questions across your library:

"What methodologies do these papers use for sentiment analysis, and where do their findings conflict?"

Every answer comes with highlight-backed citations — click through to the exact passage in the original PDF. No more "trust me" AI answers.

Grounded literature review drafts

Generate a literature review draft organized by theme, with APA in-text citations, drawn only from the papers in your library. Because the model can only cite what you actually collected, hallucinated references are structurally eliminated — then verify with our fact-checking workflow.

Privacy where it matters

Preprints, grant applications, and embargoed work don't belong on third-party clouds. PapersGPT's built-in local model server (gpt-oss, Gemma 3, Qwen 3, Phi) runs entirely offline — no API key, no data leaving your machine.

PapersGPT supports 30+ state-of-the-art models: GPT-5.6, Claude Sonnet 5, Claude Fable 5, Gemini 3.1, DeepSeek V4, Kimi K3, GLM-5.2, Grok 4 — plus local models. Premium and Business plans get automatic updates as new frontier models ship, so your workflow never goes stale.

• Business features — up to 300 PDFs per chat, full-library search up to 2,000 papers, multi-device seats for lab groups

FAQ

Is PapersGPT better than using ChatGPT directly? For research, yes, for one core reason: grounding. Generic chatbots answer from memory and hallucinate citations. PapersGPT answers only from your actual PDFs, with clickable source highlights — which is exactly what peer review demands.

Does it work with my existing Zotero library? Yes — PapersGPT reads whatever is already in Zotero 7, 8, or 9. No migration, no re-uploading.

Can it run a full systematic review? It automates the heavy lifting — screening, data extraction, synthesis — but you keep the inclusion criteria and final judgment. Combine PapersGPT with your preferred PRISMA workflow.

How do I avoid AI hallucination in my writing? Ground every claim in your library and verify citations mechanically. PapersGPT's source-grounded answers make this workflow natural; we also published a full AI fact-checking guide.
