Philosophy

Why two engines?

Speed versus quality is a personal choice — Kacy gives you both options, and the freedom to switch.

Groq — for daily life

For most smart home tasks — turning off lights, checking temperatures, triggering scenes — speed is everything. With Groq you get answers in half a second, and it costs you nothing. Perfect for anyone who just wants things to work, fast, every day.

Claude — when quality matters

Claude shines when you ask something genuinely complex: multi-step automations, ambiguous instructions, or requests that need real reasoning. Anthropic's models have an unmatched grasp of nuance and long context — worth the small monthly cost for power users.

Fast & free for everyday use. Deep & powerful when you need it.
Switch anytime — you're always in control.

There is no "wrong" choice. Kacy works brilliantly with both engines. Start with Groq for zero cost and instant responses. Upgrade to Claude whenever a request demands more intelligence. The power is yours.
