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.
Turn any text, PDF, image or book into lifelike AI speech
Voices trained on large language models deliver lifelike delivery, while Content Aware voices read the text and adjust tone to fit the material.
Speak in over 90 languages and create a custom multilingual AI voice by uploading or recording your own.
Read PDFs, Word documents, ePub, web pages and images, and scan physical books with the built-in OCR camera scanner.
Turn long readings into AI podcasts, get instant recaps, analyse screenshots and equations, chat with your document and generate practice quizzes.
