Read multiple independent signals across the text.

03
Combine

Bring the signals together into one pattern estimate.

Pattern over guesswork

Look at the writing, not the author.

LexyAI looks at observable properties of a passage — rhythm, vocabulary, repetition, punctuation and other structural patterns. The goal is to give readers a clearer view of the statistical texture of a piece of writing rather than reduce a complex judgment to a single hidden model output.

The result is an AI-pattern estimate, not proof of authorship. Human writing, edited machine writing, academic prose, marketing copy and highly structured technical text can share some of the same characteristics. That is why LexyAI presents a breakdown of signals alongside the headline score.

For longer passages, the additional context makes changes in sentence length, vocabulary use and repetition easier to measure. A detector is most useful as one analytical input among other evidence, not as a substitute for reading the underlying text.

Built for review

A quiet second opinion for text.

A

Editorial

Review drafts, articles and copy for unusually uniform or formulaic patterns.

B

Content

Add one extra signal to machine-assisted writing workflows.

C

Education

Explore measurable characteristics of writing without treating a score as proof.

D

Private review

Inspect a draft locally without sending the passage to a text-analysis API.

A practical detector

A useful second pass for modern writing.

AI writing detectors are often used when a reader wants an additional perspective on a document. LexyAI is designed for that lightweight review step: paste an article, essay, draft, report or other passage and inspect the measured signals before deciding what deserves a closer look.

The tool is intentionally transparent about uncertainty. A high AI-pattern score does not establish that a person used an AI system, while a low score does not establish that a passage was written entirely without assistance. Writing style depends on genre, editing history, subject matter and the individual choices made by the writer.

Local analysis

The passage stays with the tool.

LexyAI is designed so the text being analyzed does not need to be sent to a remote detection endpoint. See the Privacy Policy for the full scope.

AI Writing Detection

Free AI text detector for everyday writing review.

LexyAI is a free AI text detector and ChatGPT checker for examining measurable writing patterns. Paste a passage, run the analysis and review the score together with the signal breakdown.

The tool is intentionally presented as a heuristic indicator. It can help surface patterns associated with machine-generated writing, but it cannot establish authorship from text alone.
