The Turnitin AI checker is a specialized component of Turnitin’s academic integrity suite that analyzes student submissions to identify likely AI-generated or AI-paraphrased text from models like ChatGPT, Claude, Gemini, or similar tools. Integrated into Turnitin Feedback Studio, it provides educators with an AI writing indicator (percentage score), highlights suspected sections, and distinguishes between human-written, AI-generated, and AI-refined content. Designed specifically for student essays and academic writing, the Turnitin AI checker helps institutions maintain originality standards while offering insights to guide discussions on responsible AI use in education.
Is Turnitin AI Checker Free or Paid?
The Turnitin AI checker is not available for individual free use or personal purchase. It is exclusively offered through institutional licenses to schools, universities, and educational organizations—no direct access exists for students, independent educators, or non-institutional users. When an institution subscribes to Turnitin’s suite (such as Feedback Studio or Originality), the AI detection feature is typically included (sometimes as an add-on or bundled), making it “free” to end-users like students and teachers within that licensed environment. Outside institutional access, no official free tier or standalone paid option exists for the authentic Turnitin AI checker.
Turnitin AI Checker Pricing Details
Turnitin does not publish public pricing for individuals, as the AI checker is part of enterprise/institutional licensing agreements. Costs are negotiated based on institution size, student enrollment, features, and contract terms—often calculated per student annually. Here’s a representative overview based on reported ranges:
| Plan Name | Price (Monthly / Yearly) | Main Features | Best For |

| Institutional License (Standard) | Custom / ~$2–$4 per student annually (negotiated) | Core plagiarism detection + basic AI writing indicator, LMS integration, reporting | Smaller colleges, K-12 schools with basic needs |
