Edit .spark source and preview dry-run fixture output in the browser. Optional browser voice demo uses the Web Speech API. Live runs use the Spark runtime on your machine (Downloads).

Full catalog Playbooks help 

Run dry-run to see simulated fixture output for ask, classify, model, and voice ops.

Live (local only):
  1. Download or build the Spark runtime
  2. Save your program as my_program.spark
  3. Dry-run: ./spark-run.sh --dry-run my_program.spark
  4. Live: export AI_GATEWAY_URL=https://your-gateway.example/v1 then ./spark-run.sh --live my_program.spark
