Text detection guide
Screening an essay, research paper, or other writing requires pasted plain text, enough context, and the original source. This page does not read PDFs, and a single score cannot establish authorship.
Paste a complete essay, paper, or continuous passage when possible. The text panel does not read PDFs, document files, or images; short snippets provide too few vocabulary, sentence, and punctuation samples for stable analysis.
Review repetition, recurring phrases, sentence-length distribution, punctuation frequency, and unusual characters together instead of relying on one feature.
Interpret the result alongside the author, publication date, editing history, and original source. Neither a high nor low score is a verdict.
Review by use case
The same screening score carries different stakes in a classroom, a student self-check, and a publication review. Use the guide for your role to reconnect language clues with policy, process evidence, and human judgment.
Define permitted AI use first, then review the complete submission, drafts, version history, and the student’s explanation instead of treating a score as proof of misconduct.
Read the teacher AI detector guideUse complete text to locate passages worth rereading while preserving drafts, citations, and revision history. Do not damage your own voice merely to lower a detector score.
Read the student AI detector guideBefore publication, verify language signals separately from facts, citations, original sources, version records, and disclosure requirements, with an editor accountable for the decision.

This demo uses local text and image heuristics by default while video shows metadata only. Optional remote image modes return provenance or metadata clues. The index is not trained or probability-calibrated and cannot prove origin.
Frequently asked questions
Learn how plain-text essay and research paper input, rewriting, and ChatGPT attribution limits affect the interpretation of language signals.
You can paste plain text for an initial screen; this page does not read PDFs, document files, or images. At least 40 analyzable tokens are required, and a complete paragraph or longer passage is preferable.
Human rewriting, machine translation, and repeated editing can weaken or replace the original language patterns. Verify version history, cited sources, and author context as well.
Not reliably. This analysis examines repetition, sentence length, punctuation, and character structure—patterns that ChatGPT, other models, and human writing can share. It cannot attribute text to a specific model or establish authorship.
