Detectors are increasingly used on student work, often handing back a bare percentage with no explanation. Running your own draft first tells you which sentences are likely to be flagged — and, more usefully, why they read as formulaic — before a number like that reaches a teacher unexplained.
AI detectors look for patterns: even sentence rhythm, predictable vocabulary, low variation in structure. Plenty of honest writing has those qualities — especially formal academic prose, work written to a rigid template, and writing by students composing in a second language.
So a flag is not a verdict. It tells you your text shares surface patterns with AI-generated writing, which is information worth having before a teacher sees it.
Run your draft and read the sentence-level results rather than the headline number. Look at what the flagged sentences have in common.
Your strongest evidence is your process. Draft history, saved versions, notes, and outlines show your writing developing over time in a way no single score can. A ScribeLens report adds to that picture rather than replacing it — sentence-level evidence you can point to and explain, alongside your drafts, not instead of them.
Sentence-level evidence can help you understand and discuss which specific parts were flagged, but ask that any decision consider your full writing process.
Yes. You can run a guest check with no signup. A free account gives you 35,000 tokens per month, where one token covers one word.
This version does not keep a remote database of your text. Current-session and local browser state are used for usability.
Detection is pattern-based, so formal, polished, or templated writing can score higher. This is a known limitation, not evidence of wrongdoing. Read the sentence-level evidence to see which patterns triggered it.
No. Use it to spot genuinely vague or formulaic writing and improve it. Writing to game a detector tends to make your work worse, not better.
