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.
Real-time multi-modal content moderation for text, images and video
Screens text, images and video through one platform so a single set of policies can cover every content type you host.
Content is evaluated on submission so violations can be blocked or flagged before they go live, rather than in a nightly batch.
Detects policy-violating material such as abuse, unsafe imagery and other categories you need to keep off your platform.
Dedicated detectors for written content and visual content let you tune sensitivity per medium instead of forcing one threshold on everything.
