EssayCheck vs Turnitin

EssayCheck

Worth a paste before you hand in an essay: three readings in one screen, free, with no signup, and the per-sentence flags are more useful than a bare percentage. Do not treat it as an integrity tool, though. The site itself says detectors disagree with each other, the same page offers a humaniser to rewrite flagged text, and the plagiarism scan that justified the earlier paid plans has disappeared.

Pros

• +Completely free with no account, card or expiring trial
• +AI score, rubric grade and grammar check come back from one paste
• +Per-sentence flagging shows what tripped the detector instead of a single number
• +Handles up to 4,000 words in one pass

Cons

• −Humaniser and editor sit next to the detector, undermining it as evidence of anything
• −No plagiarism scan any more, and no history without an account
• −No named operating company in the terms since the August 2026 rewrite
• −No API, LMS integration or bulk upload for teachers

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
