What it is
Paperpal is an AI workspace for academic research and writing. Users can upload references and PDFs, ask questions, and receive cited findings drawn from more than 300 million verified research articles. Writing tools provide academic suggestions, paraphrasing, tone changes, word reduction, grammar correction, proofreading, and citation formatting. Its checks look for plagiarism and AI-writing patterns, review references, and assess journal submission readiness. Paperpal is available on the web and as a browser extension, with a Microsoft Word add-in and browser-extension support for Google Docs and Overleaf. The free plan includes 200 language suggestions, five generative AI uses per day, 7,000 plagiarism-check words monthly, and five daily AI-detection scans of up to 1,200 words each. Prime costs $12/month billed annually or $25/month billed monthly. Paperpal says it does not use user documents, uploads, or personal information to train its AI models, and users can delete documents. It also states that data is encrypted in transit and at rest.
