AI detector, plagiarism and content-quality checks in one scan
Classifies text as AI, original or mixed and pinpoints which sentences most influenced the score, so reviewers know exactly where to look.
Runs plagiarism matching, readability scoring, grammar and spelling fixes, guideline checks and fact/hallucination screening from the same scan.
Upload DOCX, PDF or DOC files, paste text, scan a URL, or queue large batches of documents to process at scale.
Check content inside Chrome and Google Docs, or wire detection into your own apps through the REST API and MCP server.
Write, check and reduce similarity across the whole paper lifecycle
Run similarity checks against a large comparison corpus, with several versions of checking available for different stages of a paper.
Detect how much of a document reads as AI-generated, so you can address the AIGC rate before submission.
Rewrite content to bring down both the similarity rate and the AIGC rate while aiming to preserve original formatting and meaning.
Generate drafts of literature reviews, proposals, journal articles and course papers with references and structure.
