Higher means a stronger AI writing signal. This is an estimate, not proof of authorship.
Rates how easy the text is to read on a scale from 0 to 100 — higher scores mean easier reading.
Indicates the U.S. school grade level needed to understand the text — higher education levels mean more complex reading.
Use connected paragraphs that preserve the writer’s meaning. Very short snippets, lists, quotations, and mixed-author text provide less useful context. For longer documents, check logical sections within your plan’s word limit; a passage result applies only to the passage submitted.
Reading ease and grade level describe how difficult the text may be to read. They do not establish whether it was written by a human or by AI. Technical terms can be appropriate for a specialist audience even when they increase the estimated reading level.
Paste a coherent passage, or upload a supported document on a paid plan, review the extracted text, and select Detect AI. Free scans allow up to 750 words, with 5 scans per day. Read the result alongside the actual writing and its sources.
It is the AI-writing signal returned by our detection provider. Higher values indicate a stronger AI-generation signal. It is not proof of authorship, a percentage of sentences written by AI, or a verified probability that a person used AI. Our methodology page explains the current interpretation limits.
Do not use a detector score as the sole basis for an adverse decision. Consider the writing process, relevant evidence, and a fair opportunity for the author to explain the work.
The tool displays an error so you can try again. It does not generate a substitute score when the detection service cannot return a valid result.
