What is OpenLeaf
AI-powered citation search and paper review for Overleaf. Find relevant papers to cite, paragraph by paragraph. What's new: Cross-browser support — now runs on Opera and Edge, and is Safari-ready.
OpenLeaf adds AI-powered citation search and paper review directly into the Overleaf editor — no tab switching, no workflow interruption. Also works with OpenAI Prism.
Citation Search:
- Analyzes your document paragraph by paragraph
- Searches Semantic Scholar, OpenAlex, and Google Scholar simultaneously
- Deduplicates results across all sources
- Uses LLM-based scoring to rank fetched papers
- One click to add the BibTeX entry to your .bib file
Paper Review: Two AI reviewer modes to get feedback on your papers:
- Friendly: a supportive mentor who highlights strengths and frames suggestions constructively
- Fire: the dreaded Reviewer #2 who stress-tests every claim with surgical precision
