Why AI Detectors Flag Your Text (And What You Can Actually Do About It)
I'll be honest, I didn't set out to build an AI humanizer. I stumbled into it after getting frustrated. I was writing content, using AI to speed things up, and kept running into the same wall: detectors flagging everything. Not because the content was bad. Not because it was wrong. Just because it sounded like a machine wrote it. That got me curious. What exactly are these detectors picking up on? How AI detectors actually work Most people assume AI detectors are some kind of magic. They're not. They're pattern matchers. They've been trained on massive amounts of human and AI-generated text, and they've learned to spot the difference based on a few key signals: Perplexity — AI tends to choose predictable words. Humans don't. When every sentence flows a little too smoothly, detectors notice. Burstiness — Humans naturally mix short punchy sentences with longer ones. AI output tends to be weirdly uniform in length. That rhythm gives it away. Phrase patterns — Certain phrases show up in AI
