Core Features and Plus Tools

All plans (including the Free plan) give you full access to Beaver's core features.

Chat with Your Entire Library

Turn your entire Zotero library into a searchable knowledge base. Beaver uses semantic search across titles and abstracts to find relevant papers by topic, meaning, author, or journal — not just exact keyword matches. Learn more: Searching Your Library.

Reading Assistant

Chat with open PDFs in Zotero. Select text or equations for explanations, get summaries, and compare claims against your library. The reading assistant understands the context of your paper and can answer questions about specific passages. Learn more: Reading Assistant.

Organize Your Library

Beaver helps you manage your Zotero library: create and organize collections, add tags, fix metadata, and keep everything tidy. Ask Beaver to sort, deduplicate, or restructure your references. Learn more: Editing Metadata and Library Management.

AI-Powered Automation

Automate your research flow with AI-powered actions and workflows. Set up recurring tasks, batch operations, and custom triggers. Early support is available now, with more capabilities coming soon. Learn more: Actions.

Page-Level Citations

Every answer links back to the specific page of the source PDF so you can verify claims quickly.

Local File Processing

PDFs up to 300 pages (50 MB max) are processed locally on your device. Your files are never uploaded in full — Beaver works with what's on your machine. Learn more: File Processing.

Broad Model Support

Bring your own API key (BYOK) and use models from OpenAI, Anthropic, Google, OpenRouter, and more. Choose the model that fits your needs and budget. Learn more: Using Your Own API Key.

Plus Tools

Plus Tools are included with the Plus plan and also available to Free users via credit packs (when enabling Plus Tools with your own API key in settings).

Discover New Research

Search over 240 million scholarly works from OpenAlex and other sources to find papers beyond your Zotero library. Explore related work, trace citation chains, and uncover research you might have missed. Learn more: Web Search.

Batch Processing

Process multiple PDFs at once to extract structured data. Pull out methods, findings, sample sizes, or any custom fields across a set of papers in one go.

AI-Ranking of Search Results

Uses AI models to re-rank and improve the relevance of all search results, surfacing the most useful papers first.

Cloud Processing Add-on (Beta)

The Cloud Processing add-on is currently available by invitation to beta testers. It extends Beaver with server-side document understanding for deeper, more accurate search and citation.

Full-Text Search

Keyword and semantic search across the full content of processed PDFs — find relevant sections or paragraphs, not just titles and abstracts.

Cloud-Based Document Understanding

Handles tables, figures, equations, and complex layouts that local processing can't. Documents are processed on our servers for higher-quality extraction.

Sentence-Level Citations

Citations pinpoint the exact sentence in the source text, not just the page — making it easy to verify and trace every claim.

Auto-Annotate Your PDFs

Ask Beaver to add highlights and notes directly into the PDF file based on your questions or research goals.

OCR Support

Optical character recognition for scanned PDFs. (Coming soon)
