Which LaTeX template to pick if I want to write a paper that will stay unpublished? I'd like to choose a scientific paper template in LaTeX for a Deep Learning (Artificial Intelligence) project. I think the AAAI or the IEEE are interesting, however, I'd like to know under which terms I can use their templates if my work is not intended for publication. (I am also open to suggestions of other templates or styles to consider.)
Virtually all templates available as packages on the Comprehensive TeX Archive Network (CTAN) are free to use, regardless of whether or not they're intended for submission to the journal for which they were created. If there are any specific restrictions for their use, they would be indicated somewhere in the package information.
