Are AI detectors accurate?
No detector is perfect. Review the methodology and limitations, and treat every score as evidence to investigate rather than standalone proof.
Which languages do you support?
English, Spanish, French, Italian, Portuguese and Romanian — each detected natively rather than translated into English first, which preserves the linguistic signals detection relies on.
Is my text kept private?
Yes. All detection runs in-house on Google Cloud. We do not share your text with third parties and we do not use submitted content to train models.
Which AI models can you detect?
Our model-agnostic detection covers leading families from OpenAI, Anthropic, Google, xAI, Meta, Mistral AI, DeepSeek and Alibaba — including paraphrased and lightly edited text.
Do you offer an API?
Yes — detection is available as an API for publishers, platforms and agencies. See the API page to read the spec or join the access list.
