Essai

Essai is a free AI text detector and humanizer designed to help users distinguish between AI-generated and human-written content, and refine text to sound more natural and authentic. The tool’s primary purpose is to provide clear, reliable assessments of text origin while offering instant rewriting capabilities that reduce AI-like patterns and improve readability. It is suitable for individuals and organizations that need transparent, human-sounding content across various platforms and formats.

Essai analyzes input text using AI detection models that look for linguistic patterns, structure, and stylistic markers commonly associated with large language models. The detector returns an assessment indicating the likelihood that the text is AI-generated or human-written, helping users evaluate authenticity and potential policy or compliance risks. Its humanizer feature rewrites content to reduce detectable AI signatures, adjust tone, and enhance fluency, while preserving the original meaning. The tool operates directly in the browser, with no installation required, and is designed for quick, iterative checks and revisions.
