Plagiarism Detector
Check if your text is plagiarized
What Is DeepSeek Plagiarism Detector?
DeepSeek Plagiarism Detector is an advanced AI-powered tool designed to spot copied passages, text produced by artificial intelligence, and even plagiarized code. In contrast to standard text checkers, DeepSeek doesn’t limit itself to matching words; it also examines context, writing patterns, and paraphrased text to detect subtle forms of plagiarism.
Why It Stands Out
- Dual Detection
DeepSeek identifies both human-led plagiarism and AI-generated text in a single analysis, making it a robust solution for varied content types—from essays and academic papers to technical manuals and source code. - Versatile Language & File Support
This tool can scan documents in over 30 languages and supports multiple file types. It’s a go-to resource for authors, researchers, and educators worldwide. - Actionable Feedback
Instead of merely flagging plagiarized or AI-written sections, DeepSeek provides specific suggestions for users to improve the originality of their content.
