Write LaTeX in a browser and watch the typeset PDF update beside it.
A collaborative LaTeX editor with the whole TeX distribution already installed, so a journal template compiles on the first attempt instead of after an afternoon of missing-package errors. Source on the left, rendered PDF on the right, full history, and templates for most journals and universities. It has quietly become the standard way theses get written.
Questions
A genuinely usable free tier with paid plans for volume or team features. The free plan allows one collaborator per project and enforces a short compile timeout that long documents will hit.
Yes. Overleaf sends your input to its own servers to process it. That is fine for public material; for anything containing personal data, use one of the on-device tools instead.
