What is Papersgpt For Zotero?
PapersGPT is an AI-powered plugin designed specifically for Zotero 7 and 8 that enables users to chat with academic PDFs and research papers directly within the Zotero interface. It integrates multiple advanced language models including ChatGPT (GPT-5, GPT-4o), Claude (Claude 4.5 Sonnet, Claude 4.5 Haiku, Claude 4.1 Opus), Gemini (Gemini 2.5 Pro, Gemini 2.5 Flash), DeepSeek, Qwen, Mistral, GLM4.6, and Kimi, allowing users to ask questions, get instant summaries, and gain deep insights from their PDF documents without leaving Zotero.
The tool offers powerful research assistant features including the ability to chat with multiple PDFs simultaneously, generate literature reviews from dozens of selected papers in seconds, extract insights and annotations, save notes to the Zotero library, and export or share conversation results. It supports both cloud-based commercial AI models (requiring your own API keys) and free local open-source models like Gemma 3, Qwen 3.5, gpt-oss, Llama 3.2, and Mistral that run directly on your computer for 100% data privacy.
PapersGPT is designed for academics, researchers, graduate students, postdocs, and anyone who needs to work with large amounts of PDF text efficiently. With over 1228+ happy researchers and 2.4k GitHub stars, it helps users filter through Zotero libraries at amazing speed, making literature reviews that traditionally take weeks into focused, efficient tasks completed in seconds.
