About Detector de IA

Detector de IA is a free online tool that analyzes text for patterns associated with AI-generated writing from ChatGPT, Claude, Gemini and other language models. It is used by students, bloggers, marketers and professionals who want to check academic work, articles, SEO copy or emails before sharing them.

A user pastes the content to be analyzed, from short paragraphs to longer texts, directly into the tool. The system examines statistical and linguistic characteristics associated with human writing versus AI-generated content, including cases where AI-drafted text has since been edited by a person, and returns a probability estimate of AI origin rather than a definitive verdict.

The detector works directly in the browser with no account or registration needed, and checks academic essays, articles, blog drafts, SEO and marketing copy, and professional emails. It can also analyze text written in Spanish, and is built to flag AI-generated text even after a person has edited parts of it.

Detector de IA is free to use, with analysis limited within the tool's available limits for text length. No detector offers perfect accuracy, and recommends treating its result as an additional signal within a broader review rather than definitive proof of who wrote a text.
