What does an AI detector tell you?
An AI detector estimates whether a passage contains patterns associated with generated text. Blury summarizes the result as Human, Mixed, or AI and shows the relative percentages behind that label.
A detector result is useful context, not proof of authorship. For important work, review the writing itself and keep drafts, sources, and revision history alongside the score.
Paste
Add the passage you want to check.
Detect
Review the Human, Mixed, and AI estimates together.
Decide
Use the score as one signal alongside the writing process.
Detection is an estimate, not a verdict.
Short passages, lists, quotations, and highly formal writing can produce less stable results. A longer, representative sample usually gives the detector more context.
Different services can disagree because their models and thresholds differ. Learn more in the detector results guide.
