Good to know

Questions, answered.

Everything people ask before their first check. Hover a row to stop it, or swipe through on a phone.

What is an AI detector?

An AI detector analyzes writing patterns and estimates whether a text resembles content produced by tools such as ChatGPT, Claude, or Gemini.

Can an AI detector be wrong?

Yes. Detection scores are indicators, not proof of authorship. Always review the text and its context before making a decision.

Do you store my text?

No. This preview analyzes text directly in your browser: nothing is uploaded, nothing is kept.

Is IA Checker free?

Yes. You can check text instantly without creating an account. Larger limits and saved reports will be available in paid plans.

What does the percentage mean?

It is how far the measured patterns lean artificial, not the odds that someone cheated. The verdict above it is the part meant to be read.

What is a “Humanized AI” verdict?

Text that reads unevenly, like a human wrote it, but keeps the stock connectors and impersonal register of a generator: what a paraphrasing tool leaves behind.

Which languages are supported?

English and French are measured against their own stock phrases and pronouns. Other languages still get a rhythm and punctuation reading, so treat the score as rougher.

How much text do I need?

Around 60 words for a useful reading, 200 for a confident one. Below that the result says so, and the weaker signals count for half.

Can I use this to grade someone?

Please don't. A score is a statistical indication, never proof of authorship. It is a reason to open a conversation, not to close one.
