Built from what
exists today.

Primary power. Charges in 15 minutes in nest. Best available energy density today.

Nickel-63 radioactive decay — completely safe. Powers memory and LED breathe effect. Sid never fully dies.

Thin-film photovoltaic laminated onto wings and head crown. Charges silently whenever Sid rests near light.

Two nests included — Base and Night. Add Travel or Perch nests separately ($129 each). Sid flies to the nearest dock autonomously.

Place Sid on your phone to charge. Any Qi-enabled smartphone acts as a portable nest — no cables needed on the go.

Sid's onboard BMS monitors all five sources simultaneously and routes power intelligently. Active hover uses high power — passive glide uses low. Sid never runs out because he never wastes.

Sid thinks, responds, and remembers without internet. The local model ensures he is never silent, never frozen, never dependent on a server.

When connected, Sid draws on Claude for deeper conversation. Calm, warm, unhurried — a custom voice profile built for a familiar, not an assistant.

Sid knows when his owner enters the room. He remembers routines, preferences, moods. All personal data stays on-device — private, permanent, yours.

Sid disagrees sometimes. Has moods. Flies away if ignored. Comes closer when you are distressed. Personality updates delivered silently while he sleeps in nest.

Everything Sid knows about you lives on Sid. The cloud receives only anonymised interaction patterns — and only if you choose to share them.

Sensors feed the flight controller, which passes data to the AI processor. Response flows to voice, LEDs reflect emotional state. All layers communicate as one.
