Let Claude tailor a node's lines live
Off
AI mode is off. Spark runs entirely from content.json on your phone. Later, AI mode can have Claude rewrite a variable node's options to fit what's being said (needs a small backend so your key stays private — see getSuggestionsAI()).
🔒 Privacy: transcription uses your phone's built-in speech recognition. Saved conversations stay in this browser only.
