Turnitin is a proprietary plagiarism detection software and is not available as open-source or free download. Access to Turnitin is usually provided through institutional subscriptions (universities, colleges, or research organizations). Individuals typically cannot download or use Turnitin independently without an institutional license.

If you are affiliated with a university or institution, check if they provide access to Turnitin through their library or academic services. Otherwise, there are some alternative plagiarism checkers with free or freemium options, such as:

• Grammarly (plagiarism checker included in premium)
• PlagScan (offers limited free use)
• Quetext (free tier available)
• SmallSEOTools plagiarism checker (free, but less reliable)

For official Turnitin use, you generally need to access it via your institution’s portal or learning management system
