Private by design
Chats, images and voices are created locally on your machine. No server sees them.
Your private AI character studio
Your characters. Your conversations. Your device.
Personarium is the desktop app for AI roleplay and character chat — local on your machine, with your own API keys.
Why Personarium
Still, clear, and entirely yours.
Your own keys
You connect your own API keys. No markup, no middleman.
SillyTavern-compatible
Import and export existing character cards without any loss.
Nobody reads along, nobody deletes, nobody changes the rules.
- Stored
- Only on this device. Your conversations never leave your machine.
- Your keys
- Live in your operating system's keychain — never on our servers.
- The hub
- Only sees what you deliberately share: account, membership, published cards.
