Multi-method detection approach rather than a single scoring model

Free tier available with no account required for a quick check
Accuracy claims are independently benchmarked rather than only self-reported
Bundles several content-integrity tools that would otherwise require separate subscriptions
Live plagiarism checking catches duplicate content that static-database checkers miss
Cons
English only - no multilingual detection support
Free tier limited to 2,048 characters per request
Any AI detector carries some false-positive risk on human-written text
No unlimited free tier; the free AI checker is capped at a small word count
Credit-based pricing requires tracking usage rather than a flat predictable monthly cost
Positioned mainly at publishers and agencies, so per-seat cost adds up for larger content teams
