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 PDF Annotations
Ask Beaver to "highlight the key findings" or "mark everything relevant to my project," and it adds highlights and notes to the PDF. Color-coded and ready to review. Read more.
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.
Sentence-Level Citations
Beaver cites its sources sentence by sentence, so you can trace any claim back toImproved sentence-level citations where it came from. Hover to preview the source, or click to open the highlighted PDF.
Local File Processing
PDFs and EPUBs up to 1,500 pages (100 MB max) are processed locally on your device.
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 (Soon)
The Cloud Processing add-on will be available in the future. 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.
OCR Support
Optical character recognition for scanned PDFs.
