FAQ
What systems does it work on?+
Windows 10/11 — now. macOS and Linux — in development. Minimum: 4 GB RAM, microphone.
Do I need internet?+
Yes, voice and Yukai's brain run in the cloud (Claude AI + Fish Audio). Regular home internet handles it.
How many languages does she know?+
Russian and English — fully. Others — understood, but voice is RU/EN only for now.
Can I change voice or appearance?+
Basic — free. Marketplace with voices and characters from creators (including anime artists and seiyuu) coming soon.
What does Yukai do with my data?+
Conversations are not stored on servers longer than processing. Local memory stays only on your computer.
What if I cancel my subscription?+
Access stays until the end of the paid period. Local memory and settings remain with you.
Windows says "Unknown Publisher" — is it safe?+
Yes, the app is safe — we just haven't bought a code-signing certificate yet (~$300/year). Click "More info" → "Run anyway" to install. Defender will recognize the file after a few hundred installs and stop warning. Code signing is on the roadmap.
