Straight answers
AI detector questions, without the hype.
Is AI Detector available for iPhone and Android?
Yes. AI Detector is available as a mobile app for iPhone and Android. It combines AI text detection, multi-detector signals, humanization, file import, image scanning, and history in one focused workflow.
Can I test my own text on this website?
The website lets you explore how scoring and humanization results work. To check your own text, documents, PDFs, or images, download the mobile app.
Can an AI detector prove who wrote something?
No. AI detection is probabilistic. A score can highlight patterns associated with AI-generated writing, but it should not be treated as proof of authorship or used as the sole basis for a high-stakes decision.
What kinds of writing can I check in the app?
AI Detector supports pasted text, essays, emails, blog posts, social content, documents, PDFs, and text captured from images.
Where can I download the AI Detector app?
Use the permanent download page to get AI Detector from the Apple App Store or Google Play. On a phone, the website automatically opens the store for your device.
