A QUICK SECOND OPINION

A free AI text detector, made simple.

LexyAI is a free AI text checker for anyone who wants to review an essay, article, report, email or other writing sample. It gives you a straightforward overview of patterns sometimes associated with AI-generated or AI-assisted writing, without overwhelming you with technical scores.

Check writing in seconds

Paste a passage, type directly into the editor or open a plain-text file. LexyAI reviews the sample and returns a clear result, giving you a useful first look when a piece of writing feels unusually polished, repetitive or formulaic.

A score that stays readable

The main AI-like pattern score is accompanied by two simple indicators for sentence rhythm and vocabulary variety. They describe features of the sample; they are not a verified probability that an AI system or a person wrote it.

Writing needs context

Human writing can be formal, highly edited or naturally consistent, while generated text can be revised to sound more personal. Language, subject, writing style and sample length all affect how useful an AI detector can be. Short samples are especially difficult to assess.

Private, straightforward checking

Run a text check in your browser without creating an account. The current analysis works on the text you provide in the page and does not send the sample to an analysis server. Clear the editor and check another passage whenever you need a fresh review.

No AI text detector can prove authorship from wording alone. Treat LexyAI as one clue among others, and do not use its score as the only basis for academic, professional or other consequential decisions.

FAQ

Questions about AI text checking

Can LexyAI prove whether text was written by AI?

No. It offers an indicative review, not proof of authorship or a reliable probability. Human and AI-assisted writing can look similar.

What does the score mean?

The score summarizes patterns in the sample. Read it as a starting point for review, not a final verdict about who wrote the text.

How much text should I check?

At least 50 words are required. Longer samples usually provide more context, but even a long sample cannot prove authorship.

Is my text uploaded?

The analysis runs in your browser. Your sample is not sent to an analysis server, and no account is required.

Does LexyAI work for every language?

Results vary with language, topic, writing style and sample length. Treat results cautiously for languages or writing types the tool may not handle well.
