# Nuxie Docs > Product documentation, guides, and references for building with Nuxie. Nuxie helps app builders improve activation, conversion, and retention with remotely delivered Experiences. Start with the reader's goal and framework. Use the framework SDK guide even when it targets iOS or Android. App API calls use publishable app keys; Workspace API calls use server-side bearer credentials. The documentation JSON API describes how to read these docs, not how to operate Nuxie.
