We look for AI labels and tool mentions in your text or code.

A clear check for text, captions and code
Paste your content above and choose Check text or Check code. isGenAI looks for statements such as “written with ChatGPT” and separates them from a simple mention of an AI tool. Open “How we checked” to read the matching words, then save or copy your report.
The current text detector checks labels and tool names. It does not assign a writing-style probability or certify human authorship. This makes the report useful for reviewing declared AI use without turning ordinary writing choices into an accusation.
Examples of AI-use statements
These short examples are written demonstrations of the label check. They are not samples for measuring model accuracy.
ChatGPT / OpenAI
This caption was created using OpenAI ChatGPT.
A statement that ChatGPT was used.
Claude / Anthropic
This summary was drafted with Claude.
A statement that Claude helped draft the summary.
Gemini / Google
This article was written using Google Gemini.
A statement that Gemini was used.
Code / GitHub Copilot
// This function was coded using GitHub Copilot.
An AI-use statement in a code comment; code is inspected as text and is never executed.
What a tool mention tells you
“I wrote a guide about ChatGPT” names a product. “This guide was written by ChatGPT” states that the tool was used. The report keeps those meanings separate. An OpenAI or Anthropic package import in code shows an integration, not who wrote the code.
A practical review workflow
- Check the text, caption or source-code comment.
- Read the exact AI-use statement in the report.
- For work you are reviewing, compare the statement with the author’s explanation and available drafts or version history.
- Save the result with your notes. If a result needs a closer look, use “Report a problem” below it.
Text and code are private by default. The exported report leaves out your pasted content. No account is needed for the web checker.
