About Overleaf

Overleaf is a collaborative writing and publishing system that makes the whole process of producing academic papers much quicker for both authors and publishers.

Overleaf is a free service that lets you create, edit and share your scientific ideas easily online using LaTeX, a comprehensive and powerful tool for scientific writing.

Overleaf has grown rapidly since its launch in 2012, and today there are over 2,000,000 users from over 180 countries worldwide who've created over 17 million projects using the service.

Writelatex Limited, the company behind Overleaf, was founded by John Hammersley and John Lees-Miller, two mathematicians who worked together on the pioneering Ultra PRT Project and who were inspired by their own experiences in academia to create a better solution for collaborative scientific writing.

Overleaf is supported by Digital Science. Digital Science is a technology company serving the needs of scientific research. Their mission is to provide software that makes research simpler, so there’s more time for discovery.

Whether at the bench or in a research setting, their range of products help to simplify workflows and change the way science is done. Digital Science believes passionately that tomorrow's research will be different — and better — than today's.

Their portfolio brands include Altmetric, Labguru, Figshare, ReadCube, ÜberResearch, BioRAFT and Symplectic.

Our Aims

Why did we create Overleaf? To address problems that we experienced ourselves when writing papers collaboratively, and by doing so, make the power of LaTeX accessible to all scientists and technical writers, at all stages of their career.

Most of the world's technological and medical innovations began with a scientific paper. There are two million scientific papers published every year, and many more technical reports and presentations. Scientists in academia and industry spend a lot of their time writing, reviewing and publishing these papers; that's a lot of admin & paperwork tasks. We saw a way we could help save time on these tasks, making the whole process of academic collaboration easier and more effective.

As described in the review of Overleaf on MakeUseOf.com:

“LaTeX is a document markup language that is popularly used in academia. Researchers who are writing papers or books of their own on technical topics mostly choose LaTeX to prepare their documents...To share these documents, you must first save them and then send the file to your peers online. You must also make sure that they have a text editor installed that is capable of viewing and, if necessary, editing LaTeX files … An effective [alternative] solution is offered by a site called Overleaf — it lets you write and share LaTeX from an online interface.”
