Manuscript privacy

Your research stays yours.

Unpublished work deserves clear boundaries. Here is how your manuscript is handled.

Never used for model training

We do not use your manuscripts to train AI models.

Original files are not retained

Your original manuscript file is used for the review and is not retained after processing.

Your reports remain available

Your account and review history are retained so you can return to your feedback.

Reports may include quotations and evidence excerpts that explain a finding. Your account and billing information are kept separately from original manuscript files to support your account and purchases.

Your research remains yours. PaperProof does not publish your manuscript, submit it to a journal or make it publicly searchable. You decide how to revise and when to submit.

Privacy Policy

How your manuscript, account information and review history are handled.

01Information used for your review

PaperProof processes the manuscript you upload, your optional review focus and the information needed to produce your report. Account information, review history, purchase records and messages you send to Support are handled separately from your original manuscript file.

02Your manuscript and model training

Your manuscript is provided for review, not for training AI models. We do not use your manuscripts to train AI. You retain ownership of your work. PaperProof does not publish your manuscript, submit it to a journal or make it publicly searchable.

03Original files and saved reports

Original manuscript files are not retained after processing. Your account and report history remain available so you can return to earlier feedback. Reports can contain quotations, evidence excerpts and source locations used to explain findings. Not retaining the original file does not mean that every excerpt is removed from your reports.

04Revisions and manuscript continuity

When you upload a revised draft, we process it to prepare a new review and check whether it belongs to the same manuscript. If the original file is no longer available, you may need to provide it again. The report history helps distinguish manuscript versions and review rounds.

05Service providers and necessary processing

Providing a review may involve services for AI processing, hosting, account access, payment and email delivery. Information needed for these functions may be processed by the relevant providers. Payment information is handled through the payment service; manuscript content is not needed to complete a payment.

06Account records, notifications and support

Account and purchase information is used to provide access, record manuscript credits, resolve billing questions and protect the service. Report-ready notifications use your account email; you can turn them off for a review while it is being prepared. Support receives the details you choose to include, rather than an automatic attachment of your manuscript or report.

07Retention and your choices

Original files follow the processing-only rule above. Account information and reports are retained to provide your workspace and history; purchase and support records may also be needed to resolve disputes or meet applicable recordkeeping requirements. You can edit your profile and contact Support about access, correction or deletion requests. Available rights and exceptions depend on applicable law.

08Sensitive information and questions

Upload only material you are authorized to share. Remove unnecessary patient identifiers, personal details and other sensitive information before submitting a manuscript. If you have questions about how information is handled, contact Support from your workspace and include only the details needed to explain your request.

Terms of Service

The scope of the service, your manuscript rights and what your purchase includes.

01What PaperProof provides

PaperProof provides AI-assisted feedback on academic research manuscripts, scholarly reviews and research-based academic essays. The service helps identify concerns and plan revisions before submission. It is not a journal, a publisher or a substitute for a journal’s formal peer-review process. Documents outside the supported scope may receive a notice instead of a review.

02How to use the feedback

AI-generated findings can be incomplete or incorrect. Check the cited passages, assess recommendations against your research and decide which changes are appropriate. You remain responsible for the accuracy, integrity and final wording of your manuscript. No report guarantees acceptance, publication or a particular editorial decision.

03Your account and your work

Provide accurate account information and protect access to your account. Upload only work you own or are authorized to submit, including any third-party material and research data. You retain ownership of your manuscript and authorize processing needed to deliver the review and related services.

04One-time purchases and manuscript credits

Prices and the number of credits included are shown before you purchase. A credit unlocks the full review for one manuscript, including its analyses, review history and full-report exports. Credits do not expire. Purchases are one-time payments, with no subscription or automatic renewal. A multi-manuscript pack provides the stated number of separate manuscript credits.

05Unlimited re-reviews of the same manuscript

An unlocked manuscript includes unlimited re-reviews of that same manuscript. You may change the review focus or upload a revised draft without using another credit. Revisions may change the analysis, results and wording while continuing the same research paper. Earlier reports remain separate from newly generated rounds.

06Different manuscripts and access boundaries

A different research paper requires its own credit. If a file appears to belong to a different manuscript, the review may pause and ask you to upload the original paper’s revised version or start a new review. Do not bypass access controls, reuse one manuscript’s access for unrelated papers or disrupt the service.

07Review coverage and exports

A report reflects the material available for that review. Some checks may be incomplete where text, figures or supporting information cannot be assessed. Reference checking verifies whether cited works can be located and their bibliographic details matched; it does not verify that a citation supports your argument. Full-report export covers the selected report round.

08Privacy, payments and questions

Manuscript processing and report retention are described in the Privacy Policy. If you have a purchase, access or review issue, contact Support in your workspace. Refund requests and payment disputes are considered under the purchase terms and applicable law; nothing in these terms removes rights that cannot legally be excluded.

One-time payment · No subscription required

FAQ

Common questions.

What kinds of documents can I submit?+

PaperProof is for academic research manuscripts, scholarly reviews and research-based academic essays. It is not a general-purpose document review service. Materials outside that scope receive a clear notice instead of an academic review.

How much does PaperProof cost?+

Start with a free report preview. Unlock one manuscript for $6, or choose 3 credits for $16 or 5 credits for $24. Credits never expire. Each unlocked manuscript includes all analyses, unlimited re-reviews of the same manuscript, every report round and full report PDF exports. There is no subscription.

Can I use unlimited re-reviews for a different paper?+

Unlimited re-reviews cover the same manuscript as it develops. Changes to its analysis, results or wording can be part of a revision. A separate research paper needs a new review and its own manuscript credit.

Does my Single Review credit expire?+

No. Your manuscript credits never expire. Use it when your manuscript is ready, with unlimited re-reviews of the same manuscript as you revise it.

What does one manuscript credit include?+

One paid manuscript credit includes every analysis, unlimited re-reviews of the same manuscript, all report rounds and complete report exports. A different paper uses a new credit.

Can I change the review focus?+

Yes. Re-run a review with new optional guidance while keeping the same manuscript. If you have edited your paper, upload the revised draft for a new manuscript version. Both are included after you unlock that manuscript.

What does the review assess?+

Main concerns, research methods, evidence, interpretation and reporting. The report explains the basis for each assessment and suggests concrete revision steps. It does not predict a journal’s publication decision.

Will my manuscript be used to train AI models?+

No. We do not use your manuscripts to train AI models. Your paper is provided for review, not model training.

Do you keep my paper or my reports?+

Your original manuscript file is not retained after processing. Your account and review history are retained so you can return to your feedback. Reports may include manuscript excerpts that explain the findings.

Will PaperProof publish or submit my work?+

No. Your research remains yours. PaperProof does not publish your manuscript, submit it to a journal or make it publicly searchable. You decide how to use the review.

What does reference checking verify?+

PaperProof looks up your cited works and checks their bibliographic details. Each reference receives a clear status, helping you see which sources were found and which need a closer look.

How do I start?+

Upload your academic manuscript as a PDF, DOCX, or LaTeX file. Add any areas you’d like the review to focus on, then start your review. You can also explore a sample report before uploading.
