The offline AI you've been searching for. EVA is a fully offline AI assistant that runs from a USB drive on any Windows 10 or Windows 11 PC. No internet connection. No cloud. No monthly subscription. Plug it in and your private AI starts instantly — and keeps working when the internet, Wi-Fi, or cellular network goes down.
📁 Build Your Own Offline Survival Library
EVA isn't limited to what it ships with. Load anything you can save as a TXT, DOC, or PDF — your personal information, maps and evacuation routes, military field manuals, first-aid guides, homestead SOPs, radio frequency lists, family records. EVA stores it, indexes it, and answers questions from your files — even when the grid is dark and every network is down.
Why People Search for Offline AI
Most people looking for an offline AI assistant want the same things: privacy, independence from subscriptions, and an AI that works without internet. EVA was built to answer all three. Unlike ChatGPT, Claude, or Gemini, EVA never sends a single byte to any server. Every conversation stays on your USB drive — and only your USB drive.

🌍 The Data-Center Question
Every cloud AI answer is manufactured inside a building. That building draws power from a regional grid, and most large facilities reject heat by evaporating water — water that does not come back.
Google is the only major provider publishing an audited per-prompt figure. Its May 2025 technical report puts the median Gemini text prompt at 0.24 watt-hours of electricity, 0.26 millilitres of water, and 0.03 g CO₂e — a comprehensive number that includes idle standby capacity, host CPU and RAM, and cooling overhead.
One prompt is trivial. The aggregate is not. The International Energy Agency puts global data centre consumption at 415 TWh in 2024 — about 1.5% of the world's electricity — rising to roughly 945 TWh by 2030, more than Japan uses today. The IEA also warns that about 20% of planned data centre projects are at risk of delay from grid-connection queues and equipment bottlenecks. The constraint is no longer chips. It is transformers, substations, land, and water rights.
EVA runs on hardware you already own and already power.
- Zero water at the point of use. Your computer is air-cooled. It evaporates nothing. A thousand prompts, ten thousand — exactly 0 millilitres.
- Zero marginal data-center demand. EVA issues no query to any server. It adds nothing to that load growth, nothing to the interconnection queue, and nothing to the case for the next facility, substation, or cooling tower.
- A fixed footprint, not a subscription to someone else's growth curve. You bought a drive once. Nothing accrues server-side behind your account for as long as you own it.
EVA does not make a data center more efficient. It removes your queries from one entirely. → Read the full breakdown, with sources

Frequently Asked Questions — Offline AI
Q: Is EVA truly 100% offline?
A: Yes. EVA never connects to the internet. It runs entirely from the USB drive on your local hardware. No Wi-Fi, no cloud, no pinging home to any server.
Q: Does EVA use data-center power or water?
A: No. EVA performs every calculation on your own computer, so it draws nothing from a data center and consumes no cooling water. Cloud AI answers are produced in facilities that draw grid power and evaporate water — Google reports roughly 0.26 mL per prompt. EVA's figure is zero, because no server is involved at any point. Full breakdown with sources.
Q: How is EVA different from other offline AI options?
A: Most "local AI" setups require technical installation, command-line tools, and powerful hardware. EVA is plug-and-play — no setup, no configuration, no GPU required. It is the simplest offline AI assistant available for Windows.
Q: Can I load my own survival files, maps, and field manuals?
A: Yes. Anything you can save as a TXT, DOC, or PDF — personal records, maps, field manuals, first-aid guides, SOPs — EVA reads, indexes, and answers questions about, entirely offline and entirely private.
Q: What happens to EVA if the internet, Wi-Fi, or cellular goes down?
A: Nothing. EVA keeps working exactly the same. It doesn't need any connection to function. That's the entire point of offline AI.
Q: Is $149 a one-time payment or a subscription?
A: One-time. You pay $149 once and own EVA permanently. No monthly fees. No annual renewals. Compare that to ChatGPT Plus at $240/year — EVA pays for itself in under 8 months.
