No. Evaluates internal repetition and optional pasted reference without web crawling. For example, 800-word posts scoring 96 percent unique exhibit zero 5-word overlaps. Pasted source juxtaposition spotlights matching windows for revision.
No. The similarity comparison happens entirely in your browser, only against the reference text you load on the page. Your article is never sent to a server.
Identical five-word sequences depress uniqueness percentages proportionally in sliding-window checks. For example, 95 percent and without highlighted windows suggests originality while 85-94 percent needs revision; boilerplate inflates matches. Contrast against assignment sources to pinpoint paraphrase needs before submission for 800-word posts.
Include reference passages when verifying citations, auditing student work and checking self-plagiarism across publications. For example, paste prior article alongside draft revealing recycled introductions. Address overlaps through quotation or rewriting.
Limited token windows reduce collision probability, inflating uniqueness artificially. For example, 100-word blurbs often hit 100 percent despite clichés. Demand 300-plus words for credible assessment and interpret brief outputs cautiously.
Appraise originality via five-gram sliding windows detecting internal echoes and optional reference overlaps for students, bloggers and compliance teams. Submit 800-word posts observing 96 percent unique with highlighted five-word repetitions. Reference table interprets bands: 95-100 percent equals original polished | 85-94 percent equals revise flagged windows | 70-84 percent equals substantial rewrite | below 70 percent equals duplication risk | sub-100 words equals unreliable. Example one vets thesis chapter: 800 words 96 percent passes; boilerplate methods flagged. Edge handling lowercases comparisons, strips punctuation and ignores citations marked. Scholars ensure integrity, marketers avoid duplication penalties and publishers screen submissions systematically.
Contiguous five-token windows slide across normalized text, matching internally and against pasted sources, decrementing scores per collision. Ninety-five percent and without highlights indicates freshness, while repeated taglines trigger rapid declines. Example two audits campaign: 800-word landing 78 percent due recycled slogans, paraphrased to 94 percent. Edge intricacies involve common idioms like in order to inevitably matching, quoted material requiring exclusion and tables inflating accidental overlaps. Compare assignment sources directly, set aside quoted blocks and demand 300-plus words for stability. Editors coach paraphrase, instructors demonstrate attribution and reviewers document findings every cycle.
Load 800-word draft and optional source, run analysis noting 96 percent, rephrase highlighted five-word windows, rescan confirming uplift. Local scope excludes internet indexes and academic databases; comprehensive verification needs external services. Quoted passages still match unless exempted.
