Quetext
Plagiarism checker and AI content detector

The same account includes a grammar and spell checker, an AI summarizer, the AITutorMe paraphrasing tool, an AI humanizer and a citation generator. Bulk Scan and a URL checker are also included. Quetext is used through a web app, Chrome, Firefox and Edge extensions, and a Google Docs add-on, and it also offers an MCP server and a REST developer API. The site lists support for English, French, Spanish, German and other languages.
