Use cases
Workflow shortcuts — each card opens a path in the reference or experimental Advisor.
Browse the catalogue
Start with 140 languages — the deepest layer. Models, agents, and other registries are preview snapshots.
Compare two languages
Side-by-side syntax and tradeoff fields — language compare is the most complete path today.
Advisor (experimental)
Draft a Decision Brief for a language or stack choice — verify against official docs before acting.
Switching languages or stacks
Line up syntax and mental models when you already know one ecosystem and need another.
Concept transfer
Same idea, two languages: side-by-side snippets plus difficulty and paradigm-shift hints.
AI tools & agents
Ground assistants in the language reference first; treat model/agent registry rows as preview snapshots to verify on detail pages.
New to a language
Get oriented fast: overview, typical uses, and patterns before you dive into official docs.
