What ScribeLens is

ScribeLens analyzes writing for AI-like patterns and provides sentence classifications, an overall interpretation, and an exportable report. It marks sentences as human-like, mixed, or AI-like; flagged sentences include keywords describing the pattern behind the flag. You can paste text or upload PDF, DOCX, TXT, and Markdown files, with file extraction performed in the browser. A single scan can analyze up to 40,000 words. Guest checks need no account and are limited to 2,000 words per scan and 3,500 words per day.

For academic documents, reference lists, citations, DOI and ISSN lines, publisher boilerplate, and declarations are excluded from scoring and shown in the report. Reports export as PDF or DOCX. Scanned analysis stays in the browser session and clears when the tab closes; creating a verification link stores a copy that expires after 180 days. ScribeLens says detection is probabilistic, does not identify the specific AI model or check plagiarism, and should not be used as standalone proof. A free plan is available; Pro is listed at $9/mo and marked launching soon.

Good

  • Classifies sentences and explains flagged patterns.
  • Accepts pasted text and four file formats.
  • Academic references and boilerplate are excluded from scoring.
  • Exports reports as PDF or DOCX.
  • Guest checks are available without an account.

Watch out

  • Detection is probabilistic, not standalone proof.
  • It does not identify the specific AI model.
  • It does not check plagiarism.
  • Pro at $9/mo is marked launching soon.

Who it suits

ScribeLens may suit students, educators, researchers, editors, and content reviewers who want sentence-level indicators and an exportable report. Its own limitations matter for anyone considering detection results as evidence.

Verdict

ScribeLens provides detailed sentence-level indicators and report exports, including handling for academic document sections. Treat the results as probabilistic signals, not proof, and note that its listed Pro plan is not yet available.
