Academi.cx is a service that allows users to upload academic documents to be checked for AI-generated and plagiarized content. Similarity reports are powered by Turnitin, giving you the same plagiarism insights your instructor would see. AI detection is powered by our in-house detector, benchmarked to closely mirror Turnitin's AI results.

Our in-house AI detector has been benchmarked at over 85% accuracy when compared to Turnitin's AI detection — the closest on the market. We also typically achieve 99% accuracy when detecting documents that score 0% or 100%. We were able to achieve this because we previously provided direct Turnitin AI reports, giving us access to hundreds of thousands of real Turnitin results to train and benchmark against. Most competitors simply don't have access to this volume of real-world Turnitin data, which is why their detectors fall short. Our goal isn't to be a standalone AI detector — it's to closely replicate Turnitin's AI results so you see what your teacher will see. Similarity reports are still provided directly from Turnitin.

Once you upload your document to academi.cx, it is processed within a few minutes. Your document is submitted to Turnitin for similarity analysis, and our in-house AI detector analyzes it for AI-generated content. Once processing is finished, both the similarity and AI reports, including percentages and highlights of specific content, are available on the dashboard for viewing.

The similarity score indicates how much of your document matches existing academic content. It's essentially a plagiarism score that highlights areas of your work that are similar to or directly copied from other sources.

The AI content score shows the percentage of your document that has been identified as AI-generated by our in-house detector. This score is benchmarked at over 85% accuracy compared to Turnitin, helping you see results that closely mirror what your teacher will see. Note that viewing the exact AI percentage is a premium feature available to subscribers or users who have uploaded their document using a credit.

For non-premium members, the processing time is dependent upon the queue length, in most circumstances under 3 minutes. Premium members have the ability to skip the regular queue, leading to faster processing times.

No, documents uploaded to academi.cx are not stored in Turnitin's global repository. This ensures that your work remains private and won't be used for comparison against future submissions.

No, your name and personal details are never shared with Turnitin. All documents are uploaded completely anonymously.

Absolutely. Since your document isn't added to Turnitin's global repository, you can safely submit it again without issues.

Yes, academi.cx offers a free tier. However, free users only receive similarity percentages and reports, and cannot view anything regarding flagged AI content. Premium users, on the other hand, get priority queue times, the ability to upload an unlimited number of documents, and access to AI content percentages and detailed reports. Users can also purchase credits to access the same pro features for individual documents.
