Quetext

Quetext has grown beyond its original plagiarism checker into a broader writing review suite. You can check a draft for copied passages and AI generated patterns, rewrite stiff AI text, summarize source material, fix grammar, and build citations without moving the document between several unrelated tools.

The AI Detector checks text from major models including ChatGPT, Claude, Gemini, Llama, and Mistral. Results work at sentence level, so you can see which lines triggered the detector rather than receiving one unexplained score for the whole document. The free checker accepts up to 1,000 words at a time. As with every AI detector, the result is an indicator, not proof of authorship. False positives remain possible, especially with formal or heavily edited writing.

The AI Humanizer handles the next editing pass. Paste an AI assisted draft, choose a tone and humanization strength, and Quetext rewrites the phrasing while retaining the original meaning. Natural, Formal, and Conversational modes cover common uses such as emails, articles, reports, and academic drafts. Quetext describes this as an editing tool, not a way to evade academic or publishing rules, which is the right way to use it.

The AI Summarizer turns up to 2,000 words into a paragraph, bullet list, meeting notes, or a structured report summary. You can also choose a short, medium, or long output. It works well for getting the shape of an article, transcript, research paper, or proposal quickly, though important facts still need checking against the source.

Plagiarism detection remains a major part of the product. DeepSearch checks writing against online sources, while ColorGrade feedback separates exact and near matches. Citation tools cover common academic formats, and the Chrome extension brings plagiarism and AI checks into webpages, email drafts, and browser based documents. Teams can use the REST API for publishing or learning systems.

Quetext also has a hosted MCP connector for compatible AI assistants and apps. After OAuth authorization, an assistant can submit plagiarism and AI detection reports, monitor their status, retrieve structured results, list reports, and check the account quota. This is suited to editorial agents, research workflows, and internal tools where originality checks need to happen inside the existing process.

There is a free plan for occasional checks, humanizing, and summaries. Paid plans raise monthly word allowances and add larger bulk uploads, downloadable reports, broader API use, and organization options. Quetext makes the most sense for students, educators, editors, agencies, and content teams that need both detection and revision tools. Anyone making a disciplinary, hiring, or publication decision should review the source text and supporting evidence rather than treating an AI score as a verdict.
