Our Mission

Content creation

We ensure strict separation of content and layout.
This allows building simple user interfaces for structured editing.


We want to make it easier to write together, review and discuss content in the open.


We use 100% web-technology, so we don't depend on any server infrastructure.


Our system consists of independent modules that can be customized easily.

Open Source

We release all building blocks as open source.

Substance for Developers

Substance provides an extensive, customizable content creation and annotation framework that enables user-centric interfaces and automatic data processing via your web-browser. Thanks to its modular nature it creates an ideal environment for many integration scenarios.
