WriteLaTeX is a free, collaborative, online service that lets you easily create, edit, and share mathematical, scientific, and technical content.
Launched in 2011, WriteLaTeX aims to make the power of LaTeX accessible to all scientists and technical writers.
Key features of WriteLaTeX:
Every document you create has a link that can be shared with your co-authors, and they can review, comment, and edit.
Changes from all authors synchronize transparently, so everyone always has the latest version.
The Beamer package helps you create presentations with complicated tables, figures, and graphs.
Documents are compiled in the background, so you can see the results right away.
See errors and warnings as you go, so you can catch them early.
WriteLaTeX works on iPads and other devices, so you can edit online from anywhere. There's no software to install, and no sign-up required.
