What AI Detectors Actually Flag

Understanding what gets flagged helps you write in a way that's clearly your own — whether or not you used AI tools.

These Words Flag You

"Delve", "meticulous", "nuanced", "tapestry", "underscore", "pivotal", "comprehensive", "multifaceted" — these spiked 3–28× in writing after ChatGPT launched. If your essay has 3+ of these, it will flag.

These Transitions Flag You

"Furthermore", "Moreover", "Additionally", "In conclusion", "It is worth noting" — AI uses these 4–6× more than humans. Replace with "Also", "But", "So", "This means" — normal human connectors.

Equal Paragraph Lengths Flag You

If every paragraph is 55–75 words and neatly structured, the burstiness signal fires. Human writing has one short paragraph, one long digression, one incomplete thought. Vary your paragraph lengths.

"In Conclusion" Flags You

Starting your conclusion with "In conclusion, this essay has shown..." is the clearest AI closing ritual. Human students end with their final point or a personal reflection — not a formal summary.

Student FAQ

If you wrote it yourself, it will likely score under 35%. Some human writers who use formal academic style score 35–50%. If you score above 60% on your own writing, look at the signal breakdown — transition overuse is often the issue.
If you used AI suggestions but rewrote in your own voice, scores are typically 30–55%. The key: did you keep the AI's vocabulary ("delve", "moreover") or replace with your own word choices? The vocabulary signal is the most telling.
Look at which signals fired. If vocabulary density: avoid "delve", "meticulous", "nuanced". If transitions: replace "Furthermore" and "Moreover" with "Also", "But", "So". Rescan after editing. Most human essays drop below 40% with these fixes.
