Academic grammar checker and language editor built for research papers
Paperpal is a language tool built for researchers rather than general writers. It checks grammar and punctuation against the conventions of academic English, suggests tighter academic phrasing, and offers a rewrite mode that adjusts tone for journal submission. It also flags manuscript compliance issues such as inconsistent terminology, and generates cover letters and responses to reviewers. It comes from Cactus Communications, which has long sold human editing services, so the tool sits alongside a paid manuscript-editing offering. Free checks are metered by word count, and deeper features sit in the subscription tiers.
