Copyleaks AI Detector

AI detectors are probability tools, not proof. They can misread clean, structured, or repetitive writing and produce false positives—
especially on short text or formulaic formats. These two threads focus on why human writing gets flagged and why “percentage thinking”
can lead to unfair decisions. Click a thread card to open the discussion in a new tab.

Threads

Open the false-positive thread if your human-written content was flagged. Open the score thread if the same text gets different results
across runs or people are treating a single percentage as a final verdict.

Human-Written Content Incorrectly Flagged as AI

False positives can happen when writing is highly polished, uses repeated transitions, follows a rigid template, or stays very “neutral.”
Detectors look for statistical patterns, not author intent, and those patterns can also appear in human writing—especially in technical,
academic, legal, or SEO formats.

Practical review method: test longer excerpts, compare multiple sections, and look for the specific sentences triggering flags. If only a few
parts are repeatedly highlighted, revise those for rhythm and specificity rather than rewriting everything.

AI Score Inconsistency & Over-Reliance on Percentages

AI scores can change with small edits, different text length, or even how the tool segments paragraphs. That doesn’t automatically mean the
underlying writing “became AI.” It means the detector is sensitive to surface features like repetition, uniform sentence length, and predictable
phrasing.

Best practice: use scores as a triage signal, not a verdict. Require additional evidence (draft history, writing notes, citations, human review),
and let writers appeal with context. Percentages are not proof—especially when they fluctuate.

Share the text length, the score, whether it changes across runs, and any highlighted segments. Include your context (school, client SEO,
publishing, compliance). The best answers focus on false positives and fair review rules—not score-only decisions.
