Plain-English explanation of how AI detectors score text (perplexity, burstiness, trained classifiers, watermarks), why they misfire, and how to read a score.

Why 'write like a human' prompts fail, the 7 copy-paste prompts that actually work, a 120-word Custom Instructions text, and one honest before/after.

Grammarly's grammar fixes aren't generative AI and rarely move Turnitin; its Rewrite and Paraphrase features are. Feature table, real policies, safe checklist.

Accused of using AI on work you wrote yourself? The evidence that works, ranked: version history in Docs and Word, your research trail, and how to present it.

Falsely flagged by an AI detector? Why it happens, what evidence to gather in the first 24 hours, a sample email to your professor, and how to appeal.

What Turnitin's AI score actually measures, what its under-1% false positive claim covers, what independent tests found, and what to do at each score range.

The signs of AI writing in 2026: overused words, phrase templates, structural and formatting tells, why models produce them, and why one tell proves nothing.

A five-pass editing method to humanize AI text in about 25 minutes: add what only you know, fix structure, cut AI vocabulary, restore voice, then check.
