Beaver is an AI research assistant for Zotero that helps you search your library, read PDFs, create annotations, and discover new papers from one side panel.
Beaver is an AI research assistant built for Zotero users who want help searching, reading, annotating, and organizing academic papers without leaving their library. It lives as a side panel in Zotero and is designed to work with the paper you are reading as well as the rest of your collection.
The product combines agentic library search, a reading assistant inside the Zotero PDF reader, note editing, and tools for discovering new scholarly work. Its responses are grounded in the documents you provide and supported with sentence-level citations, so it is aimed at research workflows where traceability matters.
Search across author names, titles, journal names, abstracts, and full PDF text using Beaver’s agentic search flow. It can combine metadata search, semantic reference search, hybrid full-document search, and search within specific documents.
Works inside the Zotero PDF reader so you can ask about the open paper, inspect figures and tables, and keep the conversation tied to the page you are reading.
Cites claims sentence by sentence and can open the highlighted PDF passage behind a response, making it easier to verify where an answer came from.
Creates highlights and notes in PDFs, including reviewable annotations such as key findings, comparisons to related studies, and explanations of technical terms.
Helps manage collections, add tags, and fix metadata in your Zotero library, with changes requiring your approval.
Searches beyond your local library to discover scholarly works, with pricing-page tools for external search, batch processing, and AI ranking of search results.
Ask questions about the papers in your Zotero library and get answers drawn from metadata, abstracts, and full-text PDFs.
