About

I'm a one-person hardware operation in the United States. I design, assemble and test PHNTM One by hand: a Raspberry Pi 5 desk appliance with a 10.1" touchscreen that runs its AI on the device. Chat, memory, documents, voice, a math tutor (PHNTM Tutor) and a project planner (PHNTM Missions), all in Private mode with the router unplugged. $799 once, no subscription. I publish the parts list, the measured speeds (including the slow ones), unedited transcripts and the owner manual, and I'd rather be checked than believed. Ask me the hard questions.

PHNTM One - Private AI on your desk that tutors math and plans projects

A private AI assistant you own. A Raspberry Pi 5 with a 10.1" touchscreen runs its model (Gemma 3 4B) on the device: chat, memory, reminders, voice in English, Italian and Spanish, and answers from your own documents, with the router unplugged. New: PHNTM Tutor, a math tutor that teaches how to find the answer and grades by exact arithmetic, with a Parent view; and PHNTM Missions, which turns a goal into a checked plan and keeps an honest record. $799 once, no subscription, hand-built to order.
