About PapersGPT for Zotero

PapersGPT for Zotero is an AI and MCP plugin that turns a Zotero library of PDFs into a searchable knowledge base. It goes beyond chatting with a single file by supporting synthesis across many documents and global library search. The plugin is built in native C++ and released under the AGPL-3.0 license.

It can connect to a long list of model providers, including ChatGPT, Gemini, Claude, DeepSeek, Grok, OpenRouter, Kimi, GLM, SiliconFlow, and open-weight models, and the project stresses local processing and data sovereignty. It also exposes an MCP interface so other AI tools can work with the library, and the README presents indexing speed and low memory use as design goals for libraries with thousands of PDFs.

PapersGPT suits researchers, students, and academics who manage large collections of papers in Zotero and want to ask questions of them. The input does not give pricing details, so check the project website for plans or limits.
