NudgeLearn Grader vs Turnitin

Not published. Turnitin sells to institutions and the site routes every plan question to "speak to an expert". Several capabilities relevant here, including Originality (AI writing detection) and Paper to Digital (scan and grade paper assignments), are separately licensed add-ons rather than part of the base product.

Verified on 2026-08-13 from Turnitin Feedback Studio, Turnitin: about and acquisition history. NudgeLearn is free for 20 graded items a month, then $30/month ($25 billed yearly) for 400, or $50/month ($42 billed yearly) for 1,000.

• ·Similarity checking and AI-writing detection against a repository built since 1998, across 170 languages. We do neither, and nothing in our product replaces that.
• ·Institution-wide deployment: native and LTI 1.3 integration with D2L, Canvas, Microsoft Teams, Moodle and Sakai, centrally administered.
• ·A published security posture including SOC2-certified data centers and GDPR compliance. If your district procurement asks, that decides it today.
• ·Visibility into the writing process itself through the student writing space and Draft Coach, which we do not offer.

• ·Sold to institutions. There is no published price and no way for one teacher to sign up and grade a page tonight without going through procurement.
• ·Its paper path is an add-on and it expects assessments built for it: their own description is to create tailored assessments students complete with a pen or pencil, then collect and scan them. Ours reads a page that was never designed for scanning.
• ·Built around writing and integrity. Multi-step math worked out by hand on paper is not what it is for.
• ·Feedback lands as comments and rubric scores rather than marks placed on the student’s own page with a plain-English explanation of each mistake.
• ·No per-question analytics by student, class and assignment aimed at a single teacher’s own classes.

If what you need is plagiarism and AI-writing detection across a whole institution, Turnitin is the category and we are not a substitute. Choose us when you are one teacher with a stack of handwritten pages, no template, no scanner and no purchase order. Their Gradescope line is the closer comparison for paper at scale; see our Gradescope page.

Handwritten, multi-step work that has to be read rather than pattern-matched: a page of worked algebra, a lab write-up, a paragraph response, marked directly on the student’s own page, with the per-question record kept by student, class, and assignment.

The grader works each problem out itself rather than matching an answer key, so it needs no key and accepts any equivalent form. Anything it cannot read clearly is flagged for you to confirm rather than guessed, and you can override any result. See how it works.
