ThinkStick is a complete AI system that lives on a USB drive. No installation, no internet, no cloud. Plug it into any Windows PC and it boots a private AI assistant in seconds — and takes nothing with it when you unplug.
Most "offline AI" tools still expect you to install something first. ThinkStick doesn't — the inference engine ships on the drive itself and runs directly from it.
The engine. A portable build of llama.cpp sits in the drive's own engine/ folder. It never touches the host's hard drive, registry, or startup programs.
The model. A quantized language model file sits alongside it. The engine reads it directly off the drive and runs entirely on the host machine's own processor.
The result. Unplug the drive, and the PC returns to exactly how it was. Nothing was installed, so nothing needs to be uninstalled.
Swap which model loads at launch, the way you'd swap a tool bit — one loads at a time, sized to fit real laptop hardware.
For research, summaries, and working through a concept step by step — the model to reach for when you need to think something through, not just look it up.
A specialist tuned on real code across languages — for debugging, writing, and explaining code with no internet required at all.
A reasoning-distilled model that thinks step by step before answering — built for problems where the working matters as much as the result.
Every launch opens the same way: a short boot sequence checking the engine, loading the model, and confirming the connection — then a terminal-styled chat screen, styled to match what's actually happening under the hood.
No account. No loading spinner pointed at a server somewhere else. Just a machine talking to itself.
Wherever connectivity, cost, or privacy rule out cloud AI, ThinkStick is designed to work anyway.
AI-assisted learning in classrooms without reliable internet.
Private, offline support for diagnostic centres and clinics.
Works exactly the same with zero signal.
Fits air-gapped systems by design, not as a workaround.
AI capability with no recurring cloud subscription.
For anyone who'd rather their questions stayed theirs.
Turn off the Wi-Fi. Ask it something. It still answers — because it was never asking anyone else.
