Meet bitmark: The code that makes knowledge accessible.
bitmark is the #1 content-first, open-source standard for digitizing content.
Use it, share it and help enable seamless data interoperability.
Why bitmark?
Today there are thousands of different data formats for digital content - leading to lock-ins for all. To make knowledge available we need to have a common ground - that's bitmark.
Join the bitmark Hackathon 2026
The bitmark Hackathon 2026 in Zurich and online on March 5–6, 2026, brings together a global community to rethink how learning content is created.
Under the motto “From Prompt to Product”, developers, publishers, EdTechs and innovators collaborated for 24 hours to build open-source, AI-powered editors that turn simple text prompts into interactive content – powered by the open bitmark standard.
An Open Standard With Benefits
No lock-ins anymore
bitmark ensures your data flows seamlessly between legacy systems and modern applications. It removes the "lock-in" risk by relying on an open, standard model that integrates into any digital value chain.
Structure Before Beauty
Meaning arises from structure, not typography. bitmark separates content from design, treating it as raw material with function. Design becomes interchangeable.
Content & Mobile First
bitmark is strictly content-first and mobile-first, making it better suited for modern publishing requirements. Publish your once-produced content seamlessly on multiple channels, e.g. mobile apps, CMS and even paper.
Smart & AI-Ready
bitmark empowers AI and automation to access and understand your content, making every information unit addressable and solving the problem of unstructured data in a digital world.
One System. Endless Opportunities
Stop thinking in pages or chapters. Think in building blocks. bitmark treats content as queryable, filterable, and combinable data. It’s not just a document; it’s a system. This enables endless opportunities.
More Accessibility
As a standard bitmark increases the interoperability for the digital education world. This means that learning content can be easily exchanged between different platforms.
„To enable successful digital teaching, we need seamless data exchange between the different platforms, users and learning content providers. Open standards are the foundation for this. That's why we promote and support the Open Source Standard Initiative bitmark and its goal of establishing exactly this interoperability and open standards in EdTech ecosystems.“
— Uwe Erpel, Head of Engineering at Cornelsen Publishing House
How bitmark works
bitmark lets you break down content into small independently effective information nuggets (bits) to make them available on mobile devices individually as well as grouped into chapters to create comprehensive resources.
That way content can be easily digitalized, widespread and made accessible for everyone.
Content-First vs. Layout-First
Content is often created with the layout in mind first. This results in well-designed but "dumb" PDF's and makes displaying the content on mobile phones very difficult. That's why there is so much knowledge, but little of it is digitally accessible. That needs to change, don't you think?
This is why bitmark describes the meaning of the content, not what it looks like. Computers are so empowered to understand the information and make something useful of it: Provide individual user journeys, give the right feedback at the right time, and much more. Also, complex layout information is no longer required. Instead, the optimal display is enabled by the content's meta data.
That's content-first.
