For everyday users who need a simple, one-off plagiarism and AI check on short documents, AI Detection by PlagiarismSoftware is the more accessible pick — but its free tier is severely limited (800 words) and user reviews are overwhelmingly negative (73% 1-star). TextCortex AI Content Detector API is far more powerful for developers or teams who need scalable, multilingual detection, but it has no consumer-friendly interface and unclear pricing. The biggest difference: PlagiarismSoftware is a basic web tool for quick checks; TextCortex is an API for building detection into your own apps.

Common questions
For a student, PlagiarismSoftware is easier to use because you can paste text directly into a web page. But its free tier only allows 800 words, and its poor reviews suggest it may not be reliable. TextCortex is not suitable for students because it requires programming skills to use.
No. TextCortex is an API, not a mobile app. You would need to build your own app or interface to use it on a phone. PlagiarismSoftware also has no mobile app, but its website works on a phone browser.
Based on available information, TextCortex is likely more accurate because it is frequently updated to detect newer AI models and provides heatmap-level analysis. PlagiarismSoftware's low user ratings (1.84 stars) suggest accuracy issues.
PlagiarismSoftware's free tier is limited to 800 words, which is too short for most real use cases — you'll likely need the $15/month plan. TextCortex has no free tier and requires contacting sales for pricing, so it's not practical for casual users.
PlagiarismSoftware wins for quick, simple checks on short texts; TextCortex wins for developers needing scalable, multilingual AI detection — but neither is great for the average person on a budget.
If you're a regular person who just wants to paste a paragraph and see if it's AI-written, start with PlagiarismSoftware's free tier — but be ready to pay $15/month for longer texts, and take its results with a grain of salt given the poor reviews. If you're a developer or run a business that needs to check lots of content in different languages, TextCortex is the more powerful choice, but you'll need to contact sales for pricing and have coding skills to use it.
