Pros & Cons
AIDetector.cx
+ Nailed obvious AI — a ChatGPT paragraph scored 71% (Balanced) to 98% (strict), and it named the cliché transitions to cut
+ Very low false positives — a genuine human anecdote cleared at 95% human
+ Honest by design: shows confidence tiers, flags when its two engines disagree, and publishes no inflated accuracy %
+ All-in-one at $10/mo Pro — dual-engine detector plus humanizer, plagiarism check and 19-language support
+ Explicit responsible-use framing — warns against treating a score as sole proof
− Polished, cliché-free AI can slip the Balanced engine — a naturalistic AI sample read 85% human / 'Inconclusive'
− Free tier is stingy: 5 checks for the life of the account, not per day
− Newer and less battle-tested than Originality.ai, with a smaller public track record
− The two engines often disagree, so borderline text still needs human judgment
Originality.ai
+ Highest detection accuracy we've reviewed — caught GPT-4o, Claude, and Gemini outputs
+ Combines AI detection + plagiarism check in one scan
+ Readability scoring alongside detection results
+ Team features: scan multiple URLs, export reports, API access
+ Full-site scan mode — checks entire domains, not just pasted text
− Credit model gets expensive for high-volume content operations (100K+ words/mo)
− Occasional false positives on highly formulaic human writing
− No real-time browser extension (must paste text or submit URL)
