What is Paperpal?
Paperpal is an academic-focused AI assistant that provides manuscript editing, grammar correction, citation management, and journal submission checks grounded in scholarly databases.
Paperpal is an AI-powered writing and editing platform specifically built for scholarly workflows, manuscripts, and literature reviews. Developed by Cactus Communications, the tool utilizes models trained on academic editing data and connects to an index of more than 250 million research papers. Users can upload reference documents and PDFs, search scholarly publications, generate citations in over 10,000 styles, and chat with research papers to extract key findings. In addition to literature discovery, Paperpal provides language editing tools tailored for formal journal standards. These include an academic grammar and tone checker, an AI paraphraser to adjust phrasing and trim word count, a plagiarism checker scanning against 99 billion sources, and a pre-submission readiness checker that tests manuscripts against language and formatting guidelines from over 1,500 journals. The software integrates directly into popular academic writing environments, including Microsoft Word, Google Docs, and Overleaf, enabling authors to edit without leaving their draft workspace.
Unlike generic writing assistants, Paperpal is trained specifically on scholarly edits, integrates directly into Overleaf and Word, indexes over 250 million academic papers, and includes pre-submission compliance checks for academic journals.
