Unlayer, founded by Adeel and Umair and part of YC W22, offers a solution for developers to integrate content creation tools into their applications. Their platform allows for the addition of email, web page, and document builders, supporting creation through code, visual interfaces, or AI. This aims to alleviate the complexity of building and maintaining these features from scratch.

Unlayer provides three core components: Unlayer Elements, an open-source React library for composing content in code; the Visual Builder, a drag-and-drop editor for non-technical users; and the Document Builder, designed for structured documents like proposals and invoices. These workflows share a common foundation, enabling flexibility in how content is created and managed.

Unlayer's business model involves selling hosted builder, template, and platform features to companies embedding their solutions. The commercial product encompasses a broader hosted platform with features like collaboration, storage, and exports, while Elements remains open-source. The company seeks feedback from the HN community on its expanded content creation layer.
