Can I run plain TeX on Overleaf?
Yes — you can configure your project to be compiled using plain TeX by the following:
- In the Overleaf editor, click on the "Settings" button (i.e. the gear icon next to your username in your project window).
- From the "LaTeX engine" dropdown list, select "LaTeX dvipdf". Then click "Save settings".
- Add a blank file to your project, and save it as
latexmkrc(if you do not already have this file).
- Add the following line to your
$latex = 'tex %B';
If you want to use
luatex instead, leave the "LaTeX engine" on "Automatic", and use in your
$pdflatex = 'xetex %B';
