Features
What can Kacy do?
Everything your smart home assistant should be — without giving away your data.
AI-Powered Understanding
Claude AI understands natural language — no rigid command phrases, no memorizing syntax. Just talk.
Completely Local
No cloud dependency, no subscription services. Your data stays on your hardware — always, unconditionally.
Automatic Updates
Kacy updates itself every night at 3 a.m. — no SSH, no manual work. You always get the latest version.
Voice Control via Alexa
Use your existing Echo devices as a microphone. Kacy processes everything — Alexa only relays the command.
Telegram Crash Alerts
If something goes wrong, you get an instant Telegram notification — not a silent failure at midnight.
Unlimited Voice Commands
No per-request fees, no monthly limits. Ask as much as you want — the license stays active forever.

No hidden fees. Pay once, own it — or add support for less than a coffee a week.
