Online Writing Lab (OWL), in 1994. Many colleges and universities use the Purdue OWL website as an
academic writing reference source for proper word usage, punctuation, grammar, and style. Professors criticized the partnership, begun in 2020, between OWL and the company Chegg, which provides
AI-generated "homework help" that some consider to be plagiarism. Purdue is organized into 10 colleges and schools.
