AI Detector by 8Tools

Copyleaks

Best overall

For most everyday users, Copyleaks is the stronger choice because it combines top-tier AI detection accuracy with a polished, enterprise-grade report system and broader input support (including code and images). AI Detector by 8Tools is a decent free option if you just need a quick sentence-level heatmap and don't mind a clunkier interface, but its lack of a mobile app, API, and clear pricing makes it less practical for regular use.

Common questions

Is AI Detector by 8Tools better than Copyleaks for checking a student essay?

No. Copyleaks is better because it has higher accuracy, accepts more file types (including code), and integrates with school systems like Canvas. 8Tools is fine for a quick check but less reliable for formal grading.

Can I use either tool on my phone?

Neither has a dedicated mobile app. Both work in a mobile browser, but Copyleaks is more cumbersome because its dashboard is designed for desktop. 8Tools is simpler on mobile but still not ideal.

Which tool is free?

Only AI Detector by 8Tools has a free tier (up to 5,000 characters per scan). Copyleaks offers only a trial, after which you must buy credits — there is no permanent free option.

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

AI Detector by 8Tools is easier — just paste text and click 'Deep Scan.' Copyleaks requires more steps (API keys, webhooks, role-based access) that can confuse beginners.

Can I use these tools to check if an image contains AI-generated text?

Only Copyleaks can scan images for AI text. 8Tools does not accept image inputs.

Which tool is more accurate for detecting AI-written code?

Copyleaks is designed for code (supports C++, Python, Java, JavaScript) and has higher accuracy. 8Tools focuses on natural language and may miss AI-generated code.

Copyleaks wins on accuracy and versatility for serious users; 8Tools is a decent free option for quick, casual checks.

If you're serious about AI detection — especially for school, work, or publishing — go with Copyleaks despite the cost and setup. If you just want a free, no-fuss check on a short piece of text, AI Detector by 8Tools will do the job on your laptop.
