Affiliate disclosure

Last updated: 22 July 2026.

What this means

CASRAI is a 501(c)(3) nonprofit. Most of this site — the CASRAI Dictionary, CRediT resources, implementation guides, standards documentation — is free, ad-free, and carries no commercial relationships whatsoever. The exception is our AI Writing & Research Tools hub: a small set of pages reviewing and comparing commercial AI detection and AI writing-assistant software that researchers regularly ask us about. Some links on those pages are affiliate/referral links. If you click one and sign up for the linked product, CASRAI may earn a commission — at no extra cost to you. Where a vendor has given us a discount code for readers (for example Paperpal's PAP20), we disclose that alongside the link.

Which tools this applies to

• Originality.ai — full review
• GPTZero — full review
• SciSpace — full review
• Paperpal — full review
• Jenni.ai — full review

We do not have an affiliate relationship with every tool in this category — for example, we deliberately do not cover or link Undetectable.ai, since we have no referral arrangement with them and won't fabricate one.

Editorial independence

Recommendations on these pages are based on our own research into each tool's actual features, pricing, and documented accuracy — not on which vendor pays the highest commission. We say so explicitly when a tool has a real limitation (for example: no AI detector, including the ones we link, should be the sole basis for an academic-integrity decision — false-positive rates are real and documented). If our assessment of a tool changes, the page changes; the affiliate relationship doesn't buy favorable coverage.

How this supports CASRAI's mission

Referral revenue from this small set of pages goes toward CASRAI's nonprofit work — maintaining the free CRediT taxonomy, the CASRAI Dictionary, and our standards-development activities. This is a new, small revenue stream for CASRAI, introduced in 2026. As with any nonprofit's commercial activity, whether and how affiliate income is treated for tax purposes is a standing internal policy question we keep under review with CASRAI's own finance and governance functions — this page will be updated if that policy changes.
