BYOK Desktop & Mobile Apps
Desktop and mobile apps with BYOK support run natively on your devices and connect to AI providers using your own API keys. This gives you fast, offline-capable AI tools with no browser dependency — plus the privacy benefit of API calls going directly from your device to the provider.
