Build Business-as-Code & AI-Delivered Services-as-Software

Primitives for building software where humans and AI work together seamlessly. From functions to businesses, every one of them is designed for the age of AI.

How it is written down

Two of the primitives are not runtime objects but the format everything else is authored in, and they are documented on their own sites rather than restated here:

• MDXLD — our extension of MDX. MDX is an open standard authored by the MDX community, not by us; MDXLD is ours, a superset of MDX whose frontmatter is in turn a superset of YAML-LD. Every valid MDX document is already a valid MDXLD document. The $id and $type keys are not our invention either — they come from the linked-data community's dollar-convenience context. Our one real deviation is $context, which is always https://schema.org.ai, unversioned. Also served at mdxld.org.
• MDXUI — components and layouts selected from a document's $type. Its home (ui.org.ai) is not yet serving; until it does, the packages are the documentation.

Built for the AI Era

The age of AI requires new primitives. Traditional software abstractions assume deterministic execution and human-only workflows.

• Heterogeneous Computation — Code, AI models, autonomous agents, and humans all participate in the same workflows with the same interfaces.
• Uncertain Execution — Generative and agentic functions produce variable outputs. The primitives handle retries, validation, and fallbacks transparently.
• Distributed State — Context flows across systems, conversations, and time horizons. Vector embeddings enable semantic understanding.
• Collaborative Work — AI and humans hand off tasks seamlessly. Each contributes their strengths with clear escalation paths.
