Full pricing details at hyya.ai →Why we built hYYa ai.
Every AI tool I used asked me to trust a company with my most private thoughts — my business ideas, my personal worries, my family conversations.
I wanted AI that was genuinely mine. That lived on my device. That couldn’t be read, sold, or deleted by someone else’s policy change.
hYYa ai is that. hYYa Vault is FREE because private AI shouldn’t cost a subscription. hYYa Cloud exists because sometimes you need more than your phone can carry.
We built this for everyone — the curious kid, the busy professional, the grandmother asking about her medication, the developer shipping at midnight. One app. Every level. Yours.”

Where do I use hYYa ai?
hYYa ai is live today on the web at hyya.ai — it works in any browser without a download. Native iOS, Android, and macOS apps are in active development and coming soon. One account covers all platforms.
What’s the difference between hyya.com and hyya.ai?
hyya.com is the hYYa Apps studio site — the home of all hYYa apps, our story, and this showcase. hyya.ai is the live product itself: sign in, choose your plan, and start using hYYa ai. Think of hyya.com as the portfolio and hyya.ai as the front door to the app.
How does hYYa ai relate to the other hYYa apps?
hYYa ai is the flagship app from hYYa Apps, the studio that also builds hYYa Prayer Pal and hYYa Subscriptions Tracker. All three apps share the same design philosophy — private by default, beautifully built — but serve different daily needs. You can find every hYYa app at hyya.com.
Is hYYa Vault really offline?
Yes. hYYa Vault uses AI models that run entirely on your device. Nothing is sent to any server — not your prompts, not your responses, not your conversations. It works without a Wi-Fi or mobile connection. No account is required, and it is free forever.

hYYa Vault is free forever. hYYa Cloud starts at $4.99/mo (Pro), with Elite at $14.99/mo and Ultra at $39.99/mo. All monthly plans include a 30-day free trial. Annual plans save 33%. Full pricing details are at hyya.ai/#pricing.
