Frequently Asked Questions

Everything you need to know about PlagiCheck AI

Is PlagiCheck AI completely free?

Yes. PlagiCheck AI is free to use with no sign-up, no credit card, and no usage limits from our side. The AI rewriting uses the Groq API which has a generous free tier.

Will the rewritten text pass plagiarism checkers like Turnitin?

PlagiCheck AI significantly restructures and rewrites text to reduce similarity. However, no tool can guarantee 100% results against every plagiarism checker. Always review the output before submission and use it as an aid, not a guarantee.

Is my text saved or stored anywhere?

No. Your text is processed in real-time and immediately discarded after the rewrite is complete. We do not store, log, or share any submitted content.

How does the AI Detection Score work?

Our built-in AI detector uses perplexity-based analysis — it measures sentence variety, word diversity, phrase patterns, and natural language signals. It runs entirely on the server with no external API. It provides a useful estimate; for definitive results consider using dedicated AI detection tools.

What is the maximum text length I can rewrite?

The tool works best with 50–300 words. Longer texts may take more time and could hit API rate limits. For very long content, we recommend splitting it into sections and rewriting each part separately.

Which writing mode should I use?

Use Standard for general content, Academic for essays and reports, Creative for stories and expressive writing, and Simplified for social media or plain-language content.
