Copyleaks

A tool for detecting plagiarized or AI-generated content. Verify originality with Copyleaks' AI detection, the only AI-based platform used by millions worldwide to ensure text authenticity and protect intellectual property. Copyleaks is an AI-powered platform that checks for plagiarism and detects AI-generated content in text, code, or images. It works great for students ensuring essays are original, educators grading assignments, or businesses protecting their content from copying. If you’re dealing with writing integrity, it’s a solid pick, though it shines most in education and enterprise settings. It claims over 99% accuracy for spotting AI from models like ChatGPT or Gemini, backed by third-party studies on English texts. Tests show it nails pure AI content well, but it might flag human writing as AI sometimes, especially non-native English. I think it’s reliable enough for most checks, just pair it with your own review. It scans for plagiarism in over 100 languages, like Spanish or Chinese, and AI detection covers 30+. That makes it handy if your work spans global sources, though cross-language matches can take a bit longer to process. It handles text docs, PDFs, code files like Python or Java, and even images for AI alterations. You can upload directly or use integrations like Google Docs. Limits depend on your plan, but it’s flexible for essays, code repos, or blog posts. Plans start at $13.99/month for Personal (up to 25,000 words), $74.99 for Pro, and custom for Enterprise or Education. No free trial, but you get some free scans to test. It’s affordable for individuals, might add up for heavy users though. It plugs into LMS like Canvas or Moodle, Google Docs add-ons, and APIs for custom workflows. That’s a big plus for teachers or teams wanting seamless checks without switching apps.
