ChatGPT's writing fingerprints
Watch for this cluster of habits: even sentence length and predictable structure (low burstiness); stock transitions like moreover, furthermore and in conclusion; favourite words such as delve, tapestry, testament, underscores, realm and navigating; balanced "both sides" framing that avoids a real stance; and confident but generic claims with no specific detail or sources.
The honest limits
Detection is probabilistic and beatable. Light editing, paraphrasing tools, and custom prompts that ask for bursty, human writing all reduce detectability, and false positives hit careful and non-native writers hardest. Use a score to start a conversation, not to issue a verdict — especially where stakes are high.
frequently asked
- Can ChatGPT text be detected reliably?
- Unedited ChatGPT output is often detectable, but accuracy falls sharply on paraphrased or human-edited text. Treat any detector result as a signal that warrants a closer human look.
- Does OpenAI watermark ChatGPT text?
- There is no broadly deployed, reliable text watermark for ChatGPT output, so text detection relies on statistical and linguistic analysis rather than reading a hidden marker.
