OverCite : Add Citations in LaTeX without Leaving the Editor

Abstract Adding citations while drafting in LaTeX often requires leaving the editor, searching for a paper in mind, copying its BibTeX entry into the project bibliography, renaming the cite key, and then returning to the sentence. OverCite is an open-source, lightweight tool that lets authors find, select, and insert citations without leaving the writing environment. In Overleaf, OverCite uses rough citation placeholders (e.g., \citep{Perlmutter1999} ) and local sentence context to query ADS/SciX-indexed literature, rank likely matches, and insert the selected reference, without leaving the editor. A companion VS Code extension provides the same functionality for local LaTeX projects. The ADS/SciX database includes astronomy, physics, computer science, mathematics, biology, and all indexed arXiv e-prints, making OverCite useful across a broad range of scientific disciplines.
