The free version of Duplichecker lets you check up to 1,000 words per search with unlimited daily searches. The Pro version costs about $10 monthly and increases your limit to 25,000 words per search. Pro users also get an ad-free experience, priority customer support, and full access to all writing tools including the grammar checker and paraphrasing tool. If you only need to check short pieces of content occasionally, the free version works fine. For longer documents or regular use, the Pro version offers much better value.

Duplichecker's AI content detector is pretty good at spotting text made by popular AI tools like ChatGPT. It uses smart algorithms to analyze writing patterns, vocabulary, and sentence structure. Most users report accuracy rates between 85-95% when detecting GPT-3 and GPT-4 content. It might not be as reliable with newer AI models or heavily edited AI text. For best results, check longer samples (at least a few paragraphs) since short snippets can be harder to identify correctly.

Yes! Duplichecker supports multiple languages for plagiarism checking. You can check content in Spanish, French, German, Italian, Portuguese, and several other languages. The tool compares your text against web sources in the language you're using. The AI detection feature works best with English content but can recognize patterns in other major languages too. Just paste your text or upload your document, and the system will analyze it regardless of language.

Duplichecker doesn't store your uploaded documents or pasted text permanently on their servers. Once your content is checked, it isn't saved in their system. The tool doesn't require you to create an account for basic checks, which adds another layer of privacy. However, like most online services, your data does travel through their servers during the checking process. If you're working with highly sensitive or confidential information, you might want to break it into smaller chunks or use offline alternatives.

Duplichecker is more budget-friendly and accessible than Turnitin, which is mainly for educational institutions. While Turnitin has access to academic databases and submitted student papers, Duplichecker primarily checks against web content. This means Turnitin might catch academic plagiarism better, but Duplichecker works great for bloggers, content creators, and casual users. Duplichecker also offers extra tools like grammar checking and paraphrasing that Turnitin doesn't include. For general content checking, Duplichecker provides good value, but for academic work, Turnitin's specialized database might be worth the higher cost.
