What's a Spark?
Sparks are how you pay for Watchflows AI, our hosted AI. Each AI action — building a flow, running an AI step, explaining a script — spends Sparks based on what the model actually costs, so pricier models use them faster. The Flow Builder builds with Claude Sonnet 5.5, and AI steps run on a light model. As a guide, 2,000 Sparks builds about 8 flows, or runs about 2,000 AI steps. Free Sparks run the good-value models; premium models such as Claude Opus and GPT-5.5 come with Sparks you buy, in a pack or a Cloud plan.
Your 2,000 free Sparks are spent first, then your monthly Cloud Sparks, then any packs. If you run out, your flows keep running and only the steps that use Watchflows AI pause until you buy a pack, subscribe, or switch to your own AI. Prefer your own API keys or local models? They work everywhere, with no account, and Sparks are never required.
