Free AI writing detector
ScribeLens marks every sentence, names the pattern behind each flag, and shows where the evidence sits in your document, so you can review it and make the call.
Your text is analysed in memory and never stored, unless you choose to create a verification link.
One score tells you how much. Sentence evidence tells you where. ScribeLens works sentence by sentence and keeps the evidence in front of you.
Academic writing is formal, structured and full of citations, and that alone shouldn't make it look AI-written. Before scoring, ScribeLens sets aside reference lists, citations, DOI and ISSN lines, publisher boilerplate and declaration sections such as funding and author contributions.
Start with evidence, not an accusation.
See which sentences were flagged and why, then use the report alongside drafts, revision history and a conversation with the student.
Check your writing before you submit.
See which parts of your draft may read as AI-like and why, and make your writing clearer and more specific.
Scan papers without preparing them first.
Long academic documents are analysed in one pass, with references, citations and publishing boilerplate set aside automatically.
Screen submissions with evidence you can share.
Move from a single percentage to specific passages and reasons, in a report you can attach to the editorial record.
Review drafts from writers and freelancers before they're published, and share a clear report with the author.
Teams collecting human-written text for AI training can screen submissions through the API, with sentence-level evidence for every document.
Export the analysis as PDF or DOCX, or create a verification link so others can open the same result. Share the evidence and keep the decision with people.
ScribeLens shows where the signals are and why, so your decision rests on evidence, not a single number.
