Built for where networks end.
OFFLINE AI · NO SIGNAL REQUIRED
A rugged handheld computer with on-device AI.
Built to Take the Worst.
RK3588 octa-core processor. 6 inch E-Ink display readable in direct sunlight. 160 x 100 x 12mm, 285g. IP68 waterproof. MIL-STD-810G shock, vibration, altitude. Operates from -20°C to +60°C. Bluetooth 5.3 and Wi-Fi 6 for sync when available.
Thinks Without a Tower.
Gemma 3 4B runs entirely on the device. No API call. No data leaves. No subscription. Ask it anything — survival protocols, medical triage, navigation, translation in 40+ languages — entirely offline, in any terrain, with zero connectivity.
Power That Outlasts You.
A 7000mAh battery paired with a 5W integrated solar panel. In direct sun, TARX extends its own operation indefinitely. In overcast conditions, it tops up over hours. Designed for multi-week expeditions with zero external power source.
AI that works when nothing does.
TARX runs Gemma 3 4B entirely on-device — no cloud, no signal, no subscription. Powered by the sun, sealed against water and dust, operational from the arctic to the equator. It is the first pocket AI designed not for convenience, but for survival.
Make artificial intelligence accessible at any point on the planet, in any condition, without dependency on infrastructure.
Design, build and deliver the most reliable offline AI device for operators who work at the extremes — mountaineers, special forces, humanitarian workers, first responders.
Origin Story
Named after the toughest organism on Earth.
The tardigrade has survived every mass extinction. We took notes.
Enters cryptobiosis near absolute zero — the coldest survival of any living organism ever recorded.
Documented survival with zero caloric intake. Metabolic rate drops to 0.01% of normal. Then wakes up fine.
Absorbs radiation doses 6,000x lethal to humans. DNA repair mechanisms with no known equivalent in nature.
Sent to open space on FOTON-M3 (2007). Survived. Reproduced afterward. Zero complaints filed.
"TARX is engineered on the same philosophy: radical resilience through radical simplicity."
* −272°C is the survival temperature of the tardigrade in cryptobiosis. TARX operates from −20°C to +60°C.
Every layer. Every detail.
Six precision components. One indestructible device.
Where it works.
Total darkness. Zero signal.
NVG-compatible. Silent AI queries. No radio emissions. Full situational awareness without compromising position.
-20°C. No network. No rescue.
Route navigation, avalanche risk assessment, offline AI queries — entirely solar-charged from base camp to summit, zero network dependency.
City in ruins. AI still works.
When cell towers fall and satellites are overloaded, TARX coordinates triage, translates 40 languages, and guides rescue in real time.
How TARX saves your life.
Mountain rescue. No signal. You are hypothermic and alone. This is what happens when you type into TARX.
The device. In motion.
A 90 second simulation of TARX navigating a mountain rescue scenario. No connection. No cloud. All intelligence on the device.
Four things no one else offers.
No subscription. Ever.
Garmin inReach: €430 + €25/month = €1,330 over 3 years. TARX: €399 once. No recurring fees. No data plans. No surprises.
100% private by design.
No servers, no logs, no third parties. AES-256 local encryption. Every query stays on the device. Critical for military operators and field journalists.
Solar forever.
5W monocrystalline back panel with MPPT charging. On a 30-day expedition with daily sun exposure, TARX may never need external power.
AI that improves over time.
Model swap via microSD. No new hardware required. When better models arrive, you update the card. Built to last a decade, not a product cycle.
Early access members receive priority shipping, founder pricing, and direct input on final product decisions.
