Paperpal

Paperpal is an academic writing assistant from Cactus Communications built for researchers, faculty and graduate students who write for journals and theses. It corrects grammar and tone with suggestions trained on scholarly edits, paraphrases sentences while keeping the academic register, checks a manuscript for similarity against a large source database before it reaches an institution, and answers research questions from a library of more than 250 million articles with citations generated in over 10,000 styles. Beyond editing, users upload PDFs and reference lists to question them and assemble literature reviews, generate figures with AI assistance and export them as high resolution SVG files, and run more than 30 presubmission checks against the formatting requirements of over 1,500 journals. Paperpal works in a web editor and as plugins for Microsoft Word, Google Docs, Chrome and Overleaf, so the checks run where the writing already happens. The parent company's two decades in scholarly publishing services shape the tool's focus on journal readiness rather than general prose. Institutions can license it through an enterprise arrangement. Pricing is published in US dollars on an annual basis.
