Multi-Layer Linguistic Analysis
Cross-reference against indexed publications and web sources to flag verbatim overlaps, synonym-swapped patchwriting, and synthetic AI cadence.

Inspect highlighted sentences in the split-pane assistant, apply contextual rewrites, and copy formatted APA or MLA citations.
Classification Taxonomy
How OriginalityAI categorizes text segments during deep document inspection.
Direct Plagiarism

Patchwriting & Paraphrasing
Replacing select words with synonyms while retaining the underlying clause structure and argument sequence of a source.
AI-Synthesized Cadence
Prose exhibiting uniform sentence burstiness, low perplexity variance, and formulaic transitional patterns typical of language models.
Authentic Scholarship
Original synthesis written with natural structural variation, supported by clear parenthetical citations and independent analysis.
