Categories:
Overleaf is a web-based, open-source collaborative LaTeX editor for researchers, students, academics, and technical teams to create, edit, and share professional scientific documents.
🚀 Overview
Overleaf is an online platform that makes it easy to write, edit, and collaborate on LaTeX documents in real-time, eliminating the need for local installations and simplifying complex formatting for technical content.
It solves key problems in scientific writing: producing beautifully formatted documents with formulas, tables, citations, and figures; enabling seamless team collaboration; and providing instant previews without compilation hassles. Founded in 2011 by researchers John Hammersley and John Lees-Miller, Overleaf was built to democratize LaTeX—a powerful typesetting system used in academia and science—making it accessible to beginners while supporting advanced users. Acquired by Digital Science in 2014 and merged with ShareLaTeX in 2017, it now serves over 25 million users worldwide.
The project prioritizes user-friendliness, reliability, and innovation to support the global research community.
