JustDone vs Turnitin

JustDone

JustDone's plagiarism checker is useful as one tool inside a bundle rather than a dedicated product: it catches exact and paraphrased matches and links sources, but a shopper who wants only plagiarism checking ends up paying for 30-plus unrelated writing tools at the same time. The site itself says final review and fact-checking remain the user's job.

Pros

• +Flags both verbatim copies and paraphrased matches, not just exact text
• +Links each flagged passage to its likely source
• +Bundled with AI detection and a rewriter in the same editor, so flagged text can be revised immediately

Cons

• −No standalone plagiarism-only plan; the cheapest tier bundles 35+ unrelated tools
• −The site itself cautions that users must still verify facts and do a final review manually

Turnitin

The incumbent for a reason: the submission database and the LMS integrations are what institutions buy, and no challenger matches either. Treat the AI-writing indicator as a prompt for a conversation, not a verdict; Turnitin itself now sells Clarity to show how a draft was written because a percentage alone keeps producing disputes, and the price only arrives after a sales call.

Pros

• +Largest comparison corpus of prior student submissions, which web-only checkers lack
• +LTI integrations with the major learning management systems
• +One contract covers grading, originality, exams and manuscript screening
• +Clarity adds process evidence about how a draft was written, not just a flag

Cons

• −No public pricing; every deal is an institutional quote
• −AI-writing detection produces false positives and has been contested by students
• −Student papers feed the comparison database, a long-running data-rights objection
• −The public site refuses automated fetches, which complicates monitoring
