AI Detector vs Turnitin
Academic integrity suiteTurnitin is a widely deployed academic-integrity suite whose AI-writing indicator reports whether text was written by an AI tool. AI Detector is a free zero-shot engine that runs several detection signals and reports an honest fused verdict with a per-detector breakdown. Turnitin is built for the grading workflow; AI Detector is a transparent, no-account tool you can use on its own.

| Cost | Free daily quota; paid plans and per-usage API | Institutional licence |
| Best for | Independent screening and teaching the limits of detection | Institution-wide grade workflows |

Which should you pick?
Choose AI Detector if
- You want an independent, transparent check without a grading-workflow lock-in.
- You want to show students exactly why a detector suggests a text may be AI.
Choose Turnitin if
- You need the AI indicator inside an existing similarity-and-grading workflow.
- You operate an entire institution's academic-integrity pipeline.
- Neither system can prove authorship. An AI-writing indicator, like any detector, can flag a human writer or miss edited AI text.
- A detector score should never be the sole basis for an academic penalty. Always review the human evidence.
