Overview
ScholarGraph is a comprehensive academic literature intelligence toolkit that helps researchers efficiently search, analyze, and manage academic papers using AI-powered tools. Features 11 academic search sources with intelligent domain-based source selection and PDF download capabilities.
Security & Privacy
This skill operates with the following permissions: Network Access: Queries academic APIs (arXiv, Semantic Scholar, OpenAlex, PubMed, CrossRef, DBLP, IEEE, CORE, Google Scholar, Unpaywall) and web search services File System: Reads/writes configuration files, downloads PDFs, stores knowledge graphs in SQLite database (data/knowledge-graphs.db) LLM Integration: Sends custom system prompts to AI providers for structured JSON output (concept extraction, paper analysis, etc.) Optional Python: PDF figure extraction (pymupdf) and PPT export (python-pptx) require Python 3.8+ Data Storage: All data is stored locally. No telemetry or analytics are collected. API Keys: Optional API keys are only used for their respective services and are never transmitted elsewhere. Source Code: Open source under MIT license at https://github.com/Josephyb97/ScholarGraph
