What is AI Detector?
AI Detector is an online AI content detection tool for pasted text. The official site positions it as a free AI checker with percentage scores for content generated by ChatGPT, Gemini, Claude and similar writing tools.
Core features
The public checker accepts pasted text, displays human-written and AI similarity percentages, and shows sentence, word and character counts. The site describes machine-learning and NLP-based analysis for detecting repeated phrasing, vocabulary patterns and likely AI-generated writing.
Pricing and affiliate notes
The public checker exposes a limited free flow and promotes premium access for unlimited words, but no public numeric premium price was verified in the rendered pricing page. Pricing is stored as freemium with no invented paid amount. No public affiliate commission terms were verified, so affiliate monetization is disabled.
Best fit
AI Detector is useful for writers, teachers, students, editors, content marketers and SEO teams that need a quick AI-writing probability check before publishing or reviewing text.
