TeXstudio is an integrated environment for writing LaTeX documents. Our goal is to make writing LaTeX as easy and comfortable as possible. Therefore TeXstudio has numerous features like syntax-highlighting, integrated viewer, reference checking and various assistants.
Note: The OS X version is experimental. Since none of the currently active developers are using OS X, we cannot thoroughly test it. We do our best to also support OS X, but be prepared that there may be some issues.
