For labs and departments

Buying for a group, with the paperwork handled.

Volume pricing for Paper Review, invoices your department will accept, and plain answers about where a manuscript goes. None of it needs an account, and none of it is a subscription.

Paper Review for a lab

One token per manuscript, bought in bulk

A pack is a one-time payment for Standard review tokens, emailed at purchase. Tokens never expire, so a PI can buy once and hand one to each student as their paper is ready. Each token is one review with the anonymity scan included.

$150 · $7.50 a review

20-pack

For a lab with several submissions a year. Saves $30 against buying twenty reviews one at a time.

See pack pricing → $38 · $7.60 a review

5-pack

For a small group or one busy author. Tokens work for any Standard review, in any field profile.

Buying one review for someone else, or a Deep or Journal Pack review? Buy it with your own email. The receipt email carries a link to start it, and you can forward that email to the author. The link works once, on any device, within 7 days.

Paying

Invoices, reimbursement and purchase orders

Reimbursing a card payment: Every Paper Review result page has a "Get invoice for reimbursement" button that emails a Stripe PDF invoice, with an optional line for your institution or tax ID. For packs and other purchases, email ben@purplelink.llc with the Stripe receipt.
Paying by purchase order or invoice: If your purchasing office must pay first, email ben@purplelink.llc with the quantity and billing address. A Stripe invoice follows within one business day, payable by card or US bank transfer.
ModernTex for several people: $19.99 a Mac, once. For a lab, email ben@purplelink.llc with the number of Macs and your billing address. You get one invoice and keys the lab can reassign when a student leaves.
Supplier forms: A W-9 and any supplier registration details are available on request.

Data handling

Where a manuscript goes

For a research office or ethics board, in brief. The privacy policy has the full detail.

Paper Review and the other paid checks: The manuscript is sent to Anthropic's Claude API for analysis. Under Anthropic's commercial terms, inputs are retained for up to 30 days for abuse monitoring and are not used for model training. Reference titles and DOIs are sent to CrossRef. The Paper Review report is emailed as a PDF when the review finishes, through Resend, to the address on the Stripe receipt. The manuscript is not emailed. Purplelink deletes the manuscript and the online copy within about a day after the result is first opened, or within 48 hours if it never is.
Clinical and patient data: Purplelink is not a HIPAA business associate. Do not upload protected health information or identifiable participant data. De-identify first. Unpublished results are fine because the manuscript is deleted within about a day after you open the result, and Anthropic does not train on it.
The free tools: Files sit in a temporary folder on our server only while the result is built, then they are deleted.
ModernTex and Vitae: Desktop apps. Files and records stay on your Mac unless you use an optional feature that sends them. ModernTex's AI features go to your own AI account. Vitae contacts only the services you connect, such as your mailbox or Zotero.
Payments: Stripe handles payments on its own checkout page. Purplelink never sees card details. No account is created.
Journal AI policies: Publishers let authors use AI tools on their own manuscripts, with rules on disclosure. See what ten publisher and venue policies say.

Vendor review

For your IT or research office

A data processing addendum, the subprocessor list, and a completed HECVAT Lite (a standard higher-education security questionnaire) or your department's own vendor questionnaire are available on request: ben@purplelink.llc. The security and data handling page sets out what each product does with a file, who processes it, how it is encrypted and when it is deleted.
