Most AI detectors give you one percentage. ScribeLens gives you the result and the evidence behind it: every sentence marked, the reason for each flag, and a report you can share. Here is what that looks like side by side.
A score-only detector tells you how much of a text looks AI-written. ScribeLens also shows you which sentences, why, and what was left out of the scoring.
| What you get | ScribeLens | Score-only detectors |
|---|---|---|
| The reason behind every flag. Every sentence is marked human-like, mixed or AI-like, highlighted in your document, and given the reason for its flag. | Yes: Sentence by sentence, with reasons | No: One overall percentage |
| A verdict with room for mixed writing. Graded results, from likely human-written to strong signs of AI writing, including a blend of human and AI. | Yes: Graded verdicts, including mixed | No: AI or human |
| Reference lists set aside automatically. Bibliographies, citation apparatus, DOI lines and declaration sections are excluded before scoring and shown in the report. | Yes: Automatic, no settings | No: Scored with the text, or a filter you set |
| A whole paper in one scan. With a free account, scan a full paper in one go, within 35,000 words a month. | Yes: Whole papers, free account | No: Free scans often a few thousand words or less |
| A report you can share. PDF and DOCX reports with a built-in guide to reading them. Add an optional verification link so anyone can check a printed copy against our records. | Yes: PDF and DOCX, with a reading guide | No: A score on screen |
| Trained on real student writing. The detector was retrained in October 2026 on real student essays and on essays by non-native English writers. Every report names the detector version that scored it. | Yes: Version named on every report | No: Version and training often not stated |
| Say how you used AI. Add an AI disclosure to your report: which tools you used and what for, or that you used none. Switch on writing tips for short suggestions under flagged passages. | Yes: Disclosure and writing tips | No: Not part of the result |
| Your text is not kept. Your text is analysed in memory and never stored, unless you choose to create a verification link. | Yes: Analysed in memory, not stored | Check each tool's privacy policy |
A percentage tells you how much. The sentence view tells you where and why, so you can act on the result instead of guessing.
A ScribeLens result is evidence, not proof. Read the flagged sentences and their reasons, then weigh them with what you know about the writer and how the text was produced.
Every report includes a short note headed "How to use this result", so a supervisor or committee reading the PDF can interpret it without an account.
We don't publish an accuracy percentage for ScribeLens or a comparison with any other tool, because a reader can't check a single figure. Every result shows the sentences behind it and the reason for each flag instead, so you can judge the evidence yourself. In our own testing, the detector retrained in October 2026 is markedly better at recognising genuine student writing and writing by non-native English speakers as human.
A percentage can't show you which parts of a text drove the result. Sentence-level evidence can. If a flag sits on a reference list, a quotation or a single pasted paragraph, you can see that straight away and read the rest of the document for what it is.
No. AI assistants share similar writing patterns, so a result tells you whether a passage shows AI-like patterns, not which product produced it.
No. ScribeLens looks for AI writing patterns. It does not compare your text against published sources, so use a plagiarism checker for that.
English. The detector was built and calibrated on English text, so results on other languages are not reliable.
Yes, to start. Without an account you can check up to 2,000 words per scan, 3,500 words a day. A free account checks whole papers in one scan, within 35,000 words a month, and includes PDF and DOCX reports.
Paste text or upload a PDF or DOCX. Without an account a scan covers 2,000 words; a free account checks a whole paper in one scan.
