Permissions and privacy

Page access

Paperpal reads the page, PDF, or text field you are working in to check grammar, paraphrase, summarize, or save notes, and the listing describes it working on any webpage. Limit Chrome site access to the writing and reading sites you use, such as Overleaf or journal pages.

Data notes

The listing discloses personally identifiable information, personal communications, user activity, and website content, under Cactus Communications' privacy policy. PDF chat history is saved to your Paperpal account, so check unpublished manuscripts and data against your institution's rules first.

Pricing

Free plan with monthly limits; paid Prime and Pro plans. Pricing and plan limits change more often than store metadata, so use the linked developer page as the final check before subscribing.
