PHNTM One
A private AI assistant appliance for your desk. Runs on its own hardware: works offline, no account, no subscription.
Overview
PHNTM One is a physical AI assistant you own, not an app or a cloud service. It is a small Linux computer (Raspberry Pi 5, 8 GB RAM, 10.1-inch touchscreen, speaker, push-to-talk microphone) that runs Google's open-weights Gemma 3 4B model on the device itself.
What it does: conversation with long-term memory, one-time and recurring reminders, follow-through on open loops, cited answers from your own documents, voice in and out, and a private chat on your phone served directly from the device over your own network.
Privacy you can check: by default nothing you say leaves the device. There is no account, no telemetry and no wake word. The device shows its own live outbound connections, and every claim can be verified with standard tools such as tcpdump. An optional Boosted mode (off by default) uses your own API key for harder tasks and labels every answer that left the box.
Honest limits: a 4B on-device model is far less capable than a frontier cloud model. Answers take about 15-20 seconds when warm, and about 90-106 seconds for the first answer after a long idle spell. It does not control smart-home devices.
$549 once, no subscription. Hand-built to order by a solo maker in the United States, ships in 7-10 business days with free US shipping and 30-day returns. The full bill of materials, measured benchmarks and unedited transcripts are public at phntmcore.com. If the company disappears, every unit keeps working: there are no servers.
PHNTM One is a private AI assistant appliance: a $549 desk device (Raspberry Pi 5, 10.1-inch touchscreen) that runs the Gemma 3 4B model entirely on its own hardware. Chat, long-term memory, reminders, voice and document search all work with the internet unplugged. No account, no subscription.

Who Is It For
People who want an AI assistant for memory, reminders, voice and their own documents without sending any of it to the cloud or paying a subscription.
Anyone needing frontier-level reasoning, instant answers or smart-home control. It is a small on-device model: private and useful, but slower than the cloud.
