Check your writing against the real literature
Every passage is searched across live academic databases and matched to published, open-access work — with a DOI on each source so anyone can verify the overlap. It even catches paraphrased reuse that word-for-word checks miss.
The similarity check runs as part of an AI Detector analysis — one upload gives you both the AI verdict and the source matches.

// where it searches
Live search across published research
Your text is chunked and searched across many academic databases in parallel, downloading open-access full text where it's available — so matches point to real, citable work.
This checks your writing against published and open-access literature with DOI evidence — it is not a private student-paper database, so it's built for grounding and citing your work against the real record.
// two scoring lanes
Catches copying and paraphrasing
Two independent layers run over every chunk. The semantic lane is strictly additive — it only ever finds more, and degrades gracefully if a source can't be embedded.
Word-for-word overlap
Word and n-gram Jaccard plus bigram containment catch copied and lightly-edited passages with high precision.
Paraphrase rescue
A SPECTER2 embedding layer compares meaning, not just words — surfacing reworded reuse that lexical checks alone would miss.
// evidence you can verify
Every match points to a real source
Overlap is reported chunk by chunk, and each contributing source is listed with a DOI — so a reviewer can open the original and check it in one click.
Recent work has explored transformer-based approaches to text classification. The integration of machine-learning methodologies facilitates unprecedented analytical capabilities across academic domains, particularly where labelled data is scarce.

It runs as the second half of an AI Detector analysis — one upload gives you both the sentence-level AI verdict and the source matches. There's no separate document to submit.
