Om dette verktøyet

The tool analyzes input text to identify potential matches across a broad source set and reports on originality. It targets educators, researchers, editors, and writers who need reliable verification of content integrity. By processing submissions, it helps ensure proper attribution and reduces the risk of accidental plagiarism. The system can ingest plain text, uploaded documents, or URLs, and returns a structured originality report with a similarity score and source excerpts. Conceptually, it uses multiple detection layers: exact text matches, fingerprinting for near-duplicates, n-gram overlap, and paraphrase detection via contextual embeddings. Outputs include a ranked list of sources, excerpts, and an exportable report. Core features include language detection, adjustable similarity thresholds, and selective source filtering. Use cases span student submissions, draft articles, research papers, and editorial workflows where integrity matters. The tool emphasizes speed, scalability, and privacy, enabling integration into LMS, CMS, or workflow automation. Its differentiators include multi-layer analysis, configurable privacy options, and API access for automated checks. This combination supports rigorous review while safeguarding user data.
