Crown DSL Playground
Describe a rule, computed field or transform in plain English and the production Crown DSL model — running entirely in your browser — will author the matching expression, then validate it against the real Crown DSL grammar.
Runs locally in your browser — no server
The production crown-dsl model (an INT8 build, ~44 MB) is downloaded once, cached for offline reuse, and run entirely in your browser with onnxruntime-web. Every expression is validated by the real Crown DSL checker, also bundled client-side. Nothing you type ever leaves your device. A server fallback (the ai-service harness) is available for browsers that cannot run WebAssembly.
