On-premises biometric identity verification SDKs
Face recognition, face liveness, deepfake detection, ID document recognition, ID liveness, and a combined eKYC suite — pick only what you need.
Server SDKs run on your own Linux hardware or private cloud via Docker, with air-gapped and VPC-friendly options and no per-call charges.
iOS, Android, Flutter, and React Native SDKs run matching and capture locally, including offline, so nothing is uploaded.
Layered passive and active liveness plus deepfake detection help stop presentation attacks and synthetic media.
AI detection and writing verification built for schools and editors
Paste text or upload a document and get an overall AI probability score plus a sentence-by-sentence breakdown of which parts look machine-written.
Flags AI text from major model families including ChatGPT, Gemini, Claude, Llama, and others, rather than training for a single model.
A Chrome extension and Google Docs add-on bring scanning into Gmail, Docs, Classroom, and other surfaces you already work in.
Checks content for copied passages from outside sources so you can separate AI-generation questions from originality questions.
Offers broad multilingual AI detection and text humanization, but lacks GPTZero's detailed deep-scan reporting features.
