## What Literfy Does

Literfy provides a three-step research workflow:

2. **Organize & export** — save papers to your library, export citations in BibTeX/RIS/APA/MLA/IEEE and 12+ formats, sync with Zotero/Mendeley/EndNote/Overleaf
3. **Generate literature reviews** — AI builds outlines and writes full reviews grounded exclusively in your selected papers, with linked citations
