Physical AI // NVIDIA Nemotron × Nebius Token Factory
An AI that watches your hands and stops you before you ruin it.
Fixing a phone, dicing an onion, building a bookshelf: point your phone at the work. Second Hands finds the real guide, follows you step by step, and speaks up the moment your hands go wrong.

Finds the real guide
Name the job: a repair, a recipe, a build. Tavily searches the web at runtime and Nemotron turns the guide into steps a camera can verify.

Watches your hands
A phone above your work sends a frame whenever the scene changes. The vision model checks it against the step you're on.
Super VL
Speaks up only when it matters
A mistake must show in 2 of 3 frames. A fast model decides whether to interrupt; the largest model verifies before any “Stop”.
