The context-layer coordinate for AI model applications.

A meta-category position for the infrastructure that manages, structures, and delivers context to AI models — the layer between raw data and model inference that determines what a model knows, when it knows it, and how that knowledge is assembled.

Coordinated sets this position belongs to — the coverage it extends. Counts are the live cluster size in the graph.

Why this is canonical

'Model context' is one of the most actively discussed architectural concepts in the AI infrastructure conversation — context windows, context management, retrieval-augmented generation, and Anthropic's own Model Context Protocol have made 'model context' a precise and widely understood phrase. The .app TLD positions this as an application-layer product, making it suited for developer tooling, context management platforms, and agentic workflow products.

Where it fits

A few directions this coordinate opens —

Context management infrastructure for AI
A product brand for the layer that assembles, structures, and delivers context to AI models at runtime — context stores, retrieval pipelines, and context window management tooling.
AI infrastructure companies, RAG platform builders, developer tooling vendors
MCP-adjacent application tooling
An application-layer brand for tools that implement, extend, or manage Model Context Protocol integrations — the developer-facing face of context infrastructure.
Developer tooling companies, AI application builders, MCP ecosystem participants

Illustrative, not exhaustive — held as a transferable canonical position, open to the buyer's own use.
