What is PHNTM One?
PHNTM One is a private, on-device AI assistant that runs entirely on dedicated Raspberry Pi 5 hardware (no cloud dependency by default). It offers local processing with zero telemetry, optional integration with frontier models via user-provided API keys, and both touchscreen and phone-based interfaces for interaction.

Frequently asked questions about PHNTM One
Does PHNTM One send my data to the cloud?
By default, no—all conversations and data stay on the device. The optional Boosted mode with API keys does transmit prompts to the frontier model provider.
Is a subscription required to use PHNTM One?
No. The Private mode (default) is free forever with no accounts or subscriptions. Boosted mode requires your own API key and you pay the provider directly for usage.
What hardware does it run on?
PHNTM One runs on a Raspberry Pi 5 with 8 GB RAM, Debian Linux, with an integrated touchscreen and local LLM model.
