The four articles that explain the whole field — read these and every detector score you see will make sense.

The RepDex Difference

RepDex is an independent publication built on one simple rule: We only publish claims about AI detection we've actually verified.

Tested, Not Assumed

We run real text through real detectors before we write about them — so accuracy claims you read here come from testing, not from marketing pages.

Editorial Integrity

We take zero sponsored placements from detector vendors. Our coverage says what actually works and what doesn't, never what pays us.

For Real Stakes

False positives cost students grades and writers clients. We cover AI detection with the seriousness those stakes deserve, wherever you are in the world.
