Turnitin is an academic and research integrity company that for more than 20 years has provided plagiarism/similarity detection, AI-writing detection, online grading, and feedback tools for educators, researchers, and publishers. Its market-leading integrity services are exposed to third-party platforms through the RESTful Turnitin Core API (TCA), which lets an integrating product submit a document, generate a Similarity Report, and display it to users without leaving the host platform, plus a Learning Tools Interoperability (LTI) path for LMS integrations. TCA is SOC2 compliant and runs across international data centers. Turnitin was surfaced as a portfolio company of Norwest Venture Partners and enriched into the API Evangelist network from its public developer documentation.
