# AI Detection: Why Your Human Writing Gets Flagged

The "AI look" usually comes down to two things:

**Low Perplexity:** Your word choice is predictable. If a detector can guess the next word in your sentence with high probability, it flags it as AI.**Low Burstiness:** Your sentence length is too uniform. AI tends to produce sentences of similar length and rhythm, whereas natural human speech is chaotic—mixing short, punchy sentences with long, winding ones.

If you're finding that your manual drafts are being flagged, it's usually because your prose is too "perfect" or follows a rigid academic structure. To fix this without compromising quality, you need to introduce intentional variance.

## How to Humanize Your Prose

1. **Break the Rhythm:** If you have three medium-length sentences in a row, shorten the fourth one. Make it blunt.

2. **Use Idioms and Slang:** AI is getting better at this, but subtle, context-specific colloquialisms still signal a human brain.

3. **Avoid "AI-isms":** Cut out words like "delve," "tapestry," "comprehensive," and "unlocking." These are overrepresented in LLM outputs.

4. **Inject Opinion:** AI is neutral by design. Strong, subjective claims or personal anecdotes are much harder for a detector to categorize as synthetic.

Essentially, the goal is to increase the "noise" in your writing. A deep dive into how these detectors work reveals they aren't actually looking for "AI signatures" because those don't exist—they are just looking for a lack of human irregularity.
