Common questions

Is Copyleaks better than Originality.ai for detecting ChatGPT?

Both are highly accurate, but Originality.ai has been independently tested as the most accurate for GPT-4 and GPT-5. Copyleaks is better if you need to detect AI in multiple languages.

Can I use these tools on my phone?

Neither tool has a mobile app. You can use both through a mobile browser, but the experience is clunky. For on-the-go checking, Originality.ai's website is slightly easier to navigate on a phone.

Which tool is cheaper for a freelancer scanning 10 articles a month?

Originality.ai is cheaper. At $12.95/month for unlimited scans (with a word limit per scan), it's straightforward. Copyleaks' credit system could cost more and is harder to predict.

Do these tools work with Google Docs?

Originality.ai has a Chrome extension that integrates with Google Docs to track writing history. Copyleaks offers an LMS plugin but no direct Google Docs integration.

Which tool is easier to set up for a non-technical person?

Originality.ai is much easier. You paste text or a URL and get results in seconds. Copyleaks requires you to configure API keys, webhooks, and sensitivity settings — it's built for developers.

Originality.ai wins for everyday users with its free trial, clear pricing, and simple interface; Copyleaks is overkill unless you need enterprise-grade multilingual and code scanning.

If you're a regular person — a writer, blogger, or small business owner — start with Originality.ai. It's cheaper, easier to use, and you can try it for free right now. Only consider Copyleaks if you work in a large organization that needs multilingual scanning or code plagiarism detection.
