The Device

A rugged handheld computer with on-device AI.

01 / Hardware

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.

02 / Intelligence

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.

03 / Power

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.

Vision

Make artificial intelligence accessible at any point on the planet, in any condition, without dependency on infrastructure.

Mission

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.

SURVIVES −272°C

Enters cryptobiosis near absolute zero — the coldest survival of any living organism ever recorded.

30 YEARS WITHOUT FOOD

Documented survival with zero caloric intake. Metabolic rate drops to 0.01% of normal. Then wakes up fine.

6,000× LETHAL RADIATION

Absorbs radiation doses 6,000x lethal to humans. DNA repair mechanisms with no known equivalent in nature.

VACUUM OF SPACE

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.

Where it works.

Special Forces

Total darkness. Zero signal.

NVG-compatible. Silent AI queries. No radio emissions. Full situational awareness without compromising position.

Mountaineering

-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.

First Responders

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.

Real scenario

How TARX saves your life.

Mountain rescue. No signal. You are hypothermic and alone. This is what happens when you type into TARX.

Situation: Solo mountaineer. 4,100m altitude. Temperature -12°C. Lost in fog after route error. Shaking uncontrollably. Battery on phone: dead. No cell signal. GPS satellite lock: active on TARX.
You
Shaking uncontrollably. -12C. Lost. 4100m. No signal. What do I do.
TARX AI — offline
Stage 2 hypothermia. Stop moving immediately — exertion accelerates heat loss. Find or build wind shelter now. Use terrain, a rock overhang, tarp, or bivy. Insulate from ground — critical, ground conducts cold faster than air. Remove any wet layers touching your skin. Add dry insulation to your core. Do not warm your extremities first. Eat simple sugars if available. GPS locked. Nearest staffed refuge: bearing 188°, 1.8km. Do not attempt to walk until shaking subsides. You have time. I am logging your position every 5 minutes in case rescue frequency becomes available.
You
I have a bivy and one glucose tablet.
TARX AI — offline
Deploy bivy now. Close the entry fully — trap body heat inside. Take the glucose tablet immediately. Keep core layers on only. Do not remove gloves or hat. Stay inside 40 minutes minimum before reassessing. Temperature is survivable at your current equipment level. Your biggest risk is movement, not cold. Stay still. I will alert you when your vitals stabilize or if GPS detects inactivity beyond 90 minutes.
See it in action

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.

01

No subscription. Ever.

Garmin inReach: €430 + €25/month = €1,330 over 3 years. TARX: €399 once. No recurring fees. No data plans. No surprises.

02

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.

03

Solar forever.

5W monocrystalline back panel with MPPT charging. On a 30-day expedition with daily sun exposure, TARX may never need external power.

04

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.
