AI Detection by PlagiarismSoftware

Originality.ai

Best overall

For most everyday users, Originality.ai is the better choice because it offers industry-leading accuracy for detecting GPT-4 and Claude, plus a Chrome extension that tracks writing history — making it ideal for content creators and editors who need reliable results. AI Detection by PlagiarismSoftware is cheaper and bundles plagiarism checking, but its dated interface and lack of mobile access make it less practical for daily use. The single biggest difference is accuracy: Originality.ai is built for professional-grade detection, while PlagiarismSoftware is more of a budget-friendly all-in-one checker.

Common questions

Is AI Detection by PlagiarismSoftware better than Originality.ai for checking student essays?

No, Originality.ai is better because it has higher accuracy for modern AI models like GPT-4, which students commonly use. PlagiarismSoftware can give false positives on academic citations, making it less reliable for schoolwork.

Can I use either tool on my phone?

No, neither tool has a mobile app. You need a computer with a web browser to use them.

Which tool is cheaper for occasional use?

PlagiarismSoftware is cheaper if you only need to check short texts occasionally, because it has a free tier (up to 1,000 words). Originality.ai has no free tier, so you'd have to pay even for one scan.

Does Originality.ai check for plagiarism too?

Yes, Originality.ai includes plagiarism verification as part of its scan, but its main strength is AI detection. PlagiarismSoftware also checks plagiarism, so both cover that feature.

Which tool is easier to start using for a non-technical person?

PlagiarismSoftware is slightly easier because you can just paste text or upload a file and scan immediately without creating an account. Originality.ai requires you to sign up and choose a payment plan first.

Originality.ai wins for accuracy and professional features; PlagiarismSoftware is the cheaper, simpler fallback for basic checks.

If you're serious about catching AI-written content accurately — especially from GPT-4 — go with Originality.ai. It costs a bit more and has no free tier, but the reliability is worth it for professionals. If you're on a tight budget and just need a quick check now and then, PlagiarismSoftware will do the job, just don't expect perfection.
