How it works
How to Check Text for AI-Generated Content
Paste text or upload a supported document, run the scan, and use the explainable report to guide a closer review.
Review text in four focused steps
2. Check the sample
Use 250 to 50,000 characters and include enough complete text to provide meaningful context.
3. Select Scan
Start the analysis from the text workspace with one focused action.
4. Review the report
Compare the overall assessment, confidence, and strongest flagged passages before deciding what needs closer review.
Explainable results
Understand What the Detection Report Shows
The report separates an overall assessment from the supporting passages so a result can lead to a more informed review.
A probability is a model assessment, not a literal percentage of AI-written words.
- Overall assessment and confidence
- Passages with the strongest AI risk signal
- A cautious interpretation instead of an authorship verdict

Marketers and publishers
Check incoming copy before fact-checking, brand review, and publication.
Content teams
Add a consistent editorial review step without treating one score as proof.
Responsible interpretation
Use the Result as a Signal, Not a Verdict
No detector establishes authorship with absolute certainty. Use the report to focus a thoughtful review, then consider the wider context. Keep human judgment central to consequential decisions.
- Use complete samples with enough surrounding context.
- Read highlighted wording in context before drawing conclusions.
- Compare results with the drafting process and source notes.
- Never use one score as the sole basis for a consequential decision.
