Online FACE and SPEAKER Authentication

KeyLemon cloud solution allows any developer to incorporate face and speaker and recognition technology into any web-enabled application, website or service. The KeyLemon service is available through a REST API, for which registration is required.

KeyLemonJS - The easiest way to integrate face and speaker recognition into your web app

KeyLemon also provides a ready to use web based library named KeyLemonJS to help developers integrate FACE and SPEAKER authentication in less than 30 minutes.

A complete documentation is also available, helping you understand how the API works and how to get started on a new project. Code snippets are also provided to quickly create your first apps.
