PaperPal

Paperpal is an AI writing and research assistant for academic work from CACTUS, a company in scholarly publishing services. It combines a writing workspace with language editing tuned to academic style, paraphrasing, trimming and translation, a research assistant that answers questions with citations from published articles, chat with uploaded papers, a reference library and AI-assisted figure generation. A pre-submission checker covers grammar and consistency, plagiarism, AI-text detection, reference errors and journal fit. Paperpal works in its own editor, as a Microsoft Word add-in and through Chrome and Edge extensions that support Google Docs and Overleaf.

The tool is aimed at researchers, graduate students and academic authors preparing papers, theses and other scholarly documents. Writers should follow their institution's and target journal's rules on AI assistance, and plagiarism or AI-detection scores are indicators rather than definitive judgments. Nothing was tested for this listing.

The pricing page, shown with annual billing, lists a free plan at $0 per month with 200 edits per month and limited daily use of writing and research tools. Prime costs $12 per month, billed annually at $144, with higher limits for edits, plagiarism and AI-detection checks and chat with papers.

Annual billing is advertised as saving 52%, monthly prices were not recorded, and the page offers a money-back guarantee and the option to pause or cancel.
