About AI Detector API
We build the AI content detection API we wished existed when we were shipping products with generative AI features.
Our mission
AI Detector API exists to make accurate AI text detection a first-class building block for software teams. We believe that as AI-generated content becomes ubiquitous, the platforms, schools, publishers, and marketplaces that depend on authentic human writing need a clean, fast, and reliable signal. Not a black box.
That's why we built a REST API focused on three things: accuracy, speed, and developer experience. No dashboards to learn, no complicated pricing. Just an endpoint that returns a confidence score in under a second.
What we focus on
Accuracy first
Sentence-level confidence scoring, trained against a broad mix of model outputs from GPT, Claude, Gemini, Llama, and more.
Sub-second response
Most detection requests return in under 500ms so you can call us inline from a form submission or moderation pipeline.
20+ languages
Detection that works beyond English. Including Spanish, French, German, Portuguese, Mandarin, Japanese, and more.
Developer DX
JSON in, JSON out. Clean docs, code samples in Python and JavaScript, predictable rate limits, no surprises.
Who we serve
Our customers are product teams at LMS and assessment platforms, academic integrity tools, publishing workflows, content marketplaces, recruiting platforms, and moderation pipelines. Wherever authentic human writing matters, AI Detector API is one API call away.
