About Paperpal

What is Paperpal (2026 update)

Paperpal is an AI writing tool built for researchers and academics that proofreads, paraphrases, generates text, and checks plagiarism from one workspace. It works inside Microsoft Word, Google Docs, Overleaf, and the web, and it is designed around the specific language and formatting conventions of academic and scientific writing rather than general business copy.

What is new in 2026

In 2026 Paperpal introduced CoPilot, a conversational AI integration inside Word that answers general questions about writing academic text as you work. It also added Paperpal Key, which includes autocorrect for spelling and typographical errors as you type, alongside a Grammar Check feature that flags punctuation, verb tense, and sentence structure issues in real time. A Chat PDF feature was also added, which ingests a PDF’s content so you can extract passages, get section summaries, and ask targeted questions about the document. Paperpal continued expanding integration coverage across MS Word, Overleaf, and Chrome so the same proofreading and generative tools follow you between writing environments.

Key features

  • AI proofreading and language correction tuned for academic and scientific writing
  • CoPilot conversational AI assistant inside Microsoft Word
  • Generative AI tools for rewriting, research assistance, translation, and drafting
  • Chat PDF for summarizing and querying uploaded PDF documents
  • Plagiarism checker with a detailed report
  • Citation generation and a saved citation library

Pricing in 2026

Paperpal offers a free plan plus a paid Prime tier, with additional team and institutional pricing for multiple users. The free plan includes 200 language suggestions per month, 5 AI uses per day, unlimited citation generation, and a plagiarism checker covering up to 7,000 words per month. Paperpal Prime removes most of those caps and adds unrestricted generative AI features. Prime is billed at $25/month, $55/quarter (about 27% cheaper than monthly), or $139/year (about 77% cheaper than paying monthly for a year), and a longer 3-year plan is listed at $289 total, which works out to about $8.02/month locked in before future price increases. Team plans start at $107 for 2 to 5 members.

Who should use it

Paperpal fits graduate students, academic researchers, and non-native English writers preparing journal submissions who need proofreading tuned to scientific and academic conventions rather than generic grammar checking. The Chat PDF and citation tools also make it useful for literature review work, where you need to quickly pull summaries and quotes from source PDFs while keeping a clean reference library.

Limitations and alternatives

The free plan’s caps, 5 AI uses per day and 200 language suggestions per month, are tight for anyone drafting a full paper or thesis, so serious use effectively requires Prime. Paperpal is also purpose-built for academic writing, so it is less useful for marketing copy, casual blog posts, or fiction, where a general-purpose writing assistant like Grammarly may fit better. If you specifically need plagiarism checking or citation management as separate concerns, dedicated tools like Turnitin or Zotero may serve those single needs more directly than Paperpal’s bundled approach.
