ScribeLens checks text for the writing patterns typical of ChatGPT and similar assistants. It shows you the flagged sentences and the reason for each one, so you can see what the result is based on.
Text from large language models has typical habits: consistent sentence rhythm, an even level of formality, predictable transitions, and balanced, hedged phrasing.
ScribeLens detects these patterns and marks the sentences where they appear. Careful human writing can share some of them, so each flag comes with its reason for you to check.
ChatGPT, Claude, Gemini, and other assistants write with shared patterns, so one check covers text from any of them. You do not need to know which tool was used before you scan.
The result tells you whether a passage shows AI-like patterns and where. It does not name the tool that wrote it. We retrain the detector as writing tools change, and every report names the detector version that scored it. The live version is Detector v4.0.
Start with the sentence view. Flags gathered in one section tell a different story from flags across the whole text, and reason keywords name the pattern behind each one.
The verdict is graded, from likely human-written to strong signs of AI writing. Treat it as evidence to weigh together with what you know about the writer.
It detects the patterns of AI-assisted writing, and those patterns are shared by ChatGPT and other assistants. The result shows where AI-like patterns appear in the text. It does not name the tool that produced it.
Editing changes the patterns a detector reads. AI text that has been heavily rewritten or paraphrased is harder to detect, so read a low score as evidence to weigh together with what you know about the writer.
Yes. Without an account you can check up to 2,000 words per scan. A free account gives you 35,000 words a month and 9 PDF/DOCX report exports.
Longer passages give more reliable signals, because pattern analysis has more text to work with. Paste the whole piece where you can.
