Meet bitmark: The common language for your content.
Semantic, addressable building blocks that people and machines read the same way. The source your content speaks – built for the AI era.
Content
Every page is broken into small, atomic units – each one independently meaningful and individually addressable.
bit + mark
Backend
These units become bits in bitmark, a lightweight markup language that humans and machines can read and write.
Frontend
That markup converts into clean, structured data – fast, modern and understood by virtually every system.
Why bitmark?
Digital content is scattered across PDFs, XML dialects, SCORM packages and a hundred proprietary CMS exports – each one mixing content with layout, each one a lock-in for everyone downstream.
To make content usable across systems, channels and AI, you need shared ground underneath. That's bitmark.
Solid ground you can build on
bitmark breaks content into small, independently meaningful nuggets – bits. Pure semantic code, zero layout, each with its own type, metadata and permanent address. It's the open standard at the base – one of three pillars, next to a CMS and a surface. Together they carry your content, so you're free to build your own product on top.

bitmark
as the standard
Open source, universally readable and writable. The semantic base layer everything else builds on.cms
Your content
management system
Organises bits into collections, handles versions and translations, defines via API which bits flow where.interface
Your interface
(app, API, print)
The same content ships to any surface: web, mobile, print or AI system, each in its own design, untouched.Classtime, Get More Brain, Taskbase, Didaquiz – same standard, their own systems on top.
Open by design. No lock-in, ever. 🔓
bitmark is open source. Your structured, modular data can be converted into any target format, any time – commit to the standard, not to a vendor. AI systems connect over open APIs (MCP, REST and more), so you bring your own model: your data, your terms. And bitmark slots into existing data architectures instead of replacing them.

Three things we're quietly proud of
bitmark is an open standard, and standards are supposed to be boring infrastructure nobody notices. But three things still catch people off guard.
a bit can be much
more than text
A quiz, a recipe, a calculator – a small working thing, not a description of one.humans & machines,
same source
Legible to a person and to a model at the same time. One source, two readers.Every answer
knows its origin
Each bit has an address. The citation is built in, not reconstructed afterwards.Born in education. Open to everything.
bitmark grew up in EdTech. Today the standard is universal.
About the Association
WHYKnowledge shouldn't be trapped in formats or locked behind vendors. We keep the foundation open, so it can be shared, learned and built on freely.
HowWe run bitmark as a non-profit, funded by members and donations. The community shapes the roadmap, the standard stays open source, and it answers to its users rather than to shareholders.
WhatWe maintain and evolve the open bitmark standard and grow the ecosystem around it, through an active member network, the bitmark Hackathon and an open taskpool.
Shape the standard with us.
