What is Copyleaks?

Copyleaks is an AI-powered plagiarism and AI-generated content detection platform used by educators, publishers, and businesses. Its plagiarism checker compares submitted text against web content, academic sources, and internal repositories across more than 100 languages, while its AI detector analyzes text at the sentence, paragraph, and document level to estimate the probability that content was AI-generated. A companion tool, Codeleaks, checks source code for plagiarism.

Copyleaks offers a limited free tier plus paid personal and business plans billed on a monthly credit system, with each credit covering roughly 250 words or one image. Enterprise and education customers receive custom quotes based on volume and integration needs. The platform provides an API and LMS integrations, and annual billing offers a discount over monthly pricing.
