Why this is canonical

'.app' signals a user-facing or developer-facing product, distinct from the infrastructure connotation of .ai. For a RAG platform, .app is the correct TLD for the product surface that end users or developers actually interact with — dashboards, APIs, and dev tools — while .ai holds the infrastructure authority. Together they form a coherent two-TLD RAG platform presence covering both the infrastructure and the product layer.

Where it fits

A few directions this coordinate opens —

Developer RAG tool
The application-layer product for developers building with RAG — a hosted, easy-to-use interface for ingesting documents, tuning retrieval, and integrating LLMs.
Developer tool companies, AI-first SaaS builders, hackathon and startup founders in the RAG space
Enterprise RAG application
The user-facing application surface of a RAG platform — where business users query company knowledge bases and agents retrieve grounded answers.
Enterprise knowledge management companies, internal AI tool builders, customer-facing AI assistant vendors

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