Scores come from an established third-party detection service, not a homegrown scoring trick.
You get the passages that carry the signal, not one number with no explanation.
Revise flagged passages, rescan with the same detector, and compare what changed.
Every saved version records the result and changes without pretending a score proves authorship.
Detection is the start of the workflow. Revision History keeps the draft, every rescan, and every change connected.
See the revision workflowRun a verified check and see which sentences carry the strongest signals.
Edit the flagged passage yourself or ask for a focused rewrite suggestion.
Run the same verified detector again when the draft is ready for another read.
See a word-level diff, the new result, and a saved trail of every version.
A score alone gives you nowhere to go. We surface the patterns and passages behind it, so you know where to focus your next revision.
Humans vary sentence length without thinking. Models flatten it. Detectors weight this signal hardest.
Runs of same-length sentences read machine-made. We flag every one and show you where.
Delve, seamless, robust, a testament to. The stock words that scream generative AI.
Em-dash pileups and stacked rule-of-three lists are among the loudest tells.
Start with AI detection. When you need more, check the same text for plagiarism and unsupported claims without opening another tool.
A clear result with verified sentence-level signals.
Matched sources and highlighted overlap, inline.
Claim-by-claim verdicts with sources, not just a score.
GPTZero and Originality.ai each do one thing well. Here is how they stack up against a detector that checks all three.
Paste or upload a draft and it is checked by a verified detection model. You get a clear result and sentence-level signals. With a free account, you can revise flagged passages, rescan the draft, and compare every version.
No detector, ours included, is certain on every input. Treat the result as a signal to investigate further, not proof on its own, especially on shorter drafts.
Checking your own draft before it goes out: marketing copy, LinkedIn and Reddit posts, newsletters, reports, and other professional writing. It is built for writers improving their work, not institutions policing submissions.
The free check on this page takes up to 500 words per scan and is capped at 3 scans per day. Sign up for a higher monthly word allowance and the full sentence-by-sentence report.
No. Paste or upload text in the browser and get a result in seconds. No account is needed for a quick check. A free account unlocks the revision, rescan, and version-comparison workflow.
Yes. AI detection covers a range of languages, including Spanish, French, German, Portuguese, and Chinese, and plagiarism checking covers well over a hundred. Accuracy is strongest in English and the other widely-supported languages; coverage keeps expanding.
