## What it is
PapersGPT is a Zotero plugin that lets researchers chat with single PDFs, multiple documents, or their entire library using cloud LLMs (ChatGPT, Claude, Gemini, DeepSeek) or built-in local models via Ollama. It also exposes an MCP server so AI agents can search and analyze the Zotero library locally, with citations that jump to the source paper.

## Use cases
- chat with research papers inside Zotero
- compare findings across multiple PDFs
- run a literature review across my whole Zotero library
- query academic PDFs offline with a local LLM
- let AI agents search my Zotero library via MCP
- batch-summarize 100 papers into Zotero notes
- open-source alternative to ChatPDF for researchers

## When to choose
- you already manage papers in Zotero and want AI reading built in
- you need privacy-first, offline analysis with local LLMs
- you want cross-document synthesis with clickable citations
- you want an MCP server exposing your library to AI agents

## When to avoid
- you don't use Zotero and just want a standalone PDF chatbot
- you need a fully free unlimited tool - cloud models and large-library limits are paywalled
- you need to customize the core engine - the C++ agent is closed-source despite the AGPL plugin code
