Here are some testimonies from users of XLingPaper:

Thank you so much for this program! It has made formatting hassle-free. No more worrying about example numbering or tabs going out of whack… Chantel Vanderveen, May 2015

I’m totally hooked on this program now and am very comfortable using it for all of my academic work. Stephen Marlett, June 30, 2014

I really like using XLingPaper. It’s a much better working space for me than MS Word: I can focus my attention on one section of my paper, and achieve better productivity. Joyce Wood, June 30, 2014

It was very difficult to learn XLingPaper at first, but it really paid off. It saved me so much time because I didn’t have to worry about formatting anything. I would never try to write a linguistics thesis on Word. XLingPaper formatted my thesis perfectly, and I’m especially pleased about how easy it is to add example sentences.

… my writing is better and more principled because of [XLingPaper]. Kent Rasmussen, December 17 2013

XLingPaper has been working great, and I’ve been using it to author (and translate via xml tools) most of what I write. Kent Rasmussen, August 12, 2011

[It] has enabled me to be vastly more productive in writing linguistic papers and in dialoguing with linguistic consultants. Colin Suggett, December 14, 2009
