Who this tool is for
For writers reviewing drafts, educators considering concerns fairly, and editors checking submissions without mistaking a statistical classification for evidence of misconduct.
How to use the free AI detector
Choose a coherent passage of no more than 500 words and submit it for a detection check. Keep an unchanged copy so you can connect the result to the exact text reviewed. For a longer document, check complete sections separately rather than cutting sentences apart. Do not combine section results into a document-wide probability: separate estimates do not establish overall authorship.
Include enough surrounding prose to make the passage meaningful. A heading, slogan, bibliography, or short answer may provide little useful context. If you exclude references, quotations, or tables, note that choice; the result applies only to the submitted material. Humanizely supports 15 languages, but language support should not be interpreted as equal reliability across every genre or passage. Remove confidential information before submission and check applicable privacy requirements.
What an AI detection result can—and cannot—tell you
AI detectors broadly use statistical classification to identify patterns associated with particular kinds of generated and human-written text. That is different from observing the writing process. Predictable phrasing, standardized formats, translation, and editing can complicate interpretation. Human writing can receive an AI-associated classification, while generated writing can go unflagged.
If a result looks concerning, validate the concern against independent evidence: draft history, research notes, source annotations, and the writer’s explanation of their choices. Check whether the passage contains quotations or required template language. In consequential settings, allow the writer to respond and follow the relevant review procedure. Neither a concerning result nor an apparently reassuring one proves authorship. Do not use detection alone to assign grades, reject applicants, or accuse a contributor.
Revise for accuracy and clarity, not a promised pass
After checking a draft, identify actual writing problems: unsupported conclusions, vague actors, repetitive summaries, or missing explanations. Revise those problems while preserving the evidence. Verify citations against the original sources, and keep dates, dimensions, numerical claims, and documented achievements unchanged unless you have a justified correction.
For academic and admissions work, the submission must remain your original work within institutional rules. Disclose AI assistance when required; rewriting does not make prohibited assistance acceptable. Keep dated drafts and a brief revision log rather than repeatedly changing words to chase a different classification. Humanizely does not guarantee detector outcomes.
