Copyleaks

Checking a student essay for copied passages and for text written by an AI model is the kind of job Copyleaks handles.

Copyleaks is an AI content detector and plagiarism checker that scans writing in multiple languages and flags both copied material and machine-generated text.

Teachers, publishers and businesses can run those checks without leaving the systems they already use, because Copyleaks connects through an API and through LMS integrations.

That makes it a practical fit for schools that want detection built into their course platform, or for developers who want to add it to their own product.

Copyleaks also offers writing assistance made for catching errors, so you can clean up a draft after checking it.

Two cautions apply.

False positives are possible, so a flagged passage needs a human read before anyone is accused of anything.

And AI detection will not catch every form of plagiarism.

The pricing model is listed as free, but the cost may still be a barrier for individual users who need regular access.
