Overview

PapersGPT is a Zotero plugin (.xpi) that indexes PDFs locally and answers questions over a single paper, a selection, or the entire library, with click-to-jump citations. It adds Literature Radar for daily digests from arXiv, PubMed and other sources, AutoPilot for batch-reading collections into Zotero Notes, and an MCP server. Models can be 30+ cloud LLMs, built-in local models, Ollama, or any OpenAI-compatible endpoint.

Who it is for: Researchers using Zotero who want local, cited Q&A over their paper library

Strengths

  • Parsing, indexing and search run locally; local LLMs work fully offline
  • Benchmark: 10,000 PDFs indexed in about 7 minutes, 19.5 ms average query
  • Works with Ollama, custom OpenAI-compatible endpoints, or built-in Hugging Face local models
  • Exposes the Zotero library to Claude Desktop, Cursor and other clients via MCP

Weaknesses

  • Tied to Zotero 7 to 10; unusable outside Zotero
  • README points to 'Professional' capabilities on the website, so free versus paid scope is unclear
  • Indexing 10,000 PDFs used 2.21 GB RSS and 901 MB of index
  • Download links in the README point to different versions (v2.1.0 and v2.2.0)

What it needs

  • GPU optional
  • Needs Zotero 7+, Ollama (optional)
  • Models: OpenAI, Claude, Gemini, DeepSeek, Grok
