Quetext
Best overallFor most everyday users, Quetext is the better all-around tool because it combines plagiarism detection, AI detection, and grammar checking in one easy-to-use platform, while AI Detector by SEOToolZone is a free but limited option best for quick, one-off AI checks. The single biggest difference is that Quetext offers a full writing toolkit for a low monthly price, whereas SEOToolZone is free but cluttered with ads and capped at 2,000 words per scan.

Common questions
No, Quetext is better for essays because it handles longer documents and also checks plagiarism, which is important for academic work. SEOToolZone is fine for a quick check on a short paragraph, but its 2,000-word limit makes it impractical for full essays.
Neither tool has a dedicated mobile app, but both websites work in a mobile browser. Quetext's interface is cleaner on a small screen, while SEOToolZone's ads can be annoying on mobile.
Both tools are reasonably accurate for common AI models like GPT-3.5 and GPT-4, but no detector is perfect. Quetext tends to give more nuanced results with additional context, while SEOToolZone gives a simple percentage score that can be misleading on borderline cases.
Only if you regularly write or review content — for example, if you're a student submitting multiple essays a month or a blogger publishing weekly. If you only need an AI check once in a while, stick with SEOToolZone's free tool.
No, SEOToolZone only accepts plain text or .txt files. Quetext supports PDF and Word document uploads, which is much more convenient for working with existing files.
Quetext wins for everyday use with its all-in-one plagiarism and AI detection, while SEOToolZone is a decent free backup for quick, short checks.
If you're a student, blogger, or professional who regularly writes and needs to check for both plagiarism and AI content, go with Quetext — the $7.99/month is a small price for a clean, reliable tool. If you just want a free, no-fuss AI detector for short texts and don't mind ads, AI Detector by SEOToolZone will do the job in a pinch.
