Free AI-Writing Check to Use Alongside a Plagiarism Checker
Worried the coursework you will also check for source matches may be flagged? Preview how the analyzed text reads to OmniDetect, inspect the passages that reacted, revise for original analysis, supported claims, citations, and meaning, then recheck the new version.
This preview cannot determine authorship, reproduce the teacher or institution's checker, or replace the institution’s source-use and AI-assistance policy.
Preview my documentWhat the checker-view preview shows
A bounded view of the analyzed excerpt—not a decision by the recipient.
Observed result
The result band and passages that reacted within the text OmniDetect actually analyzed.
Revision target
Places to inspect for original analysis, supported claims, citations, and meaning; never an instruction to disguise the writing process.
Decision boundary
The teacher or institution can use a different method and applies the institution’s source-use and AI-assistance policy.

Preview the submitted version
Paste the same draft you plan to send and confirm the analyzed scope before interpreting the result.
Revise what needs real improvement
Review the reacted passages for original analysis, supported claims, citations, and meaning. Preserve correct material instead of chasing a score.
Recheck the revision
Compare the new OmniDetect result. A changed signal is useful feedback from this method, not a promise about another checker.
Pre-submission review checklist
- Read the institution’s source-use and AI-assistance policy before submitting.
- Confirm the analyzed range and method boundary shown with the result.
- Review passages for original analysis, supported claims, citations, and meaning.
- Keep factual claims, quotations, citations, names, and dates correct.
- Preserve normal drafts and version history as part of the writing record.
- Do not change correct writing solely to imitate a supposedly “human” style.
Evidence and limits behind this workflow
Reviewed 2026-08-27Turnitin Guides
Its current guide says the model can misidentify human and AI-written text and should not be the sole basis for adverse action.
Scope: Turnitin product guidance for qualifying submission prose; it does not validate OmniDetect or describe every recipient’s process.
Liang et al., Patterns (2023)
The study found substantial false-positive risk for 91 human-written TOEFL essays across seven detectors.
Scope: A small, specific non-native-English essay dataset; evidence of risk, not a universal rate for this page or OmniDetect.
