AI in the news

Your own AI that no one can switch off.

Ready-made, private and offline. A US$29 download that sets up a small AI on your laptop, with Wikipedia, WikiMed and US maps beside it.

Your questions never leave your laptop. There's no account and no login, and it keeps answering with the Wi-Fi off. It runs on an ordinary Windows or Mac laptop with 8 GB of RAM.

One payment, instant download, 30 days to change your mind.

Made in New Zealand.

How do I fix a bike puncture?

Offline assistant

1. Lever one side of the tyre off the rim.

2. Pump a little air in, listen for the hole.

3. Roughen, glue, patch, refit, pump.

Check it: Wikipedia, "Bicycle tire".

How answers look: short steps, plus the article to check them against.

Everything you ask lives on someone else's server, under their rules.

ChatGPT, Claude and Gemini answer from data centres you'll never see. That works well most of the time. It also means the company decides when it's up, what changes and what happens to your questions.

It can go down. Every online service has bad days. OpenAI lists its own on a public status page, dated. Most are partial: one feature down, slower answers, or more errors than usual.

It can change. Plans, limits and models change on the provider's timetable, not yours.

It sees what you ask. What you type goes to their servers and is handled under their privacy policy, not yours.

OpenAI's status page posted 25 incidents in 30 days. See the history

Counted from status.openai.com, read 1 Nov, 15:08 NZT. Most were partial, not full outages, which is normal for any big online service. Counts for Anthropic, Cloudflare and GitHub are on AI Watch.

A private AI now fits on an ordinary laptop.

Small open AI models now run without the cloud. Ours is a 4B model, about 2.7 GB, that runs on a laptop with 8 GB of RAM and no graphics card. You ask in plain English, the way you'd ask ChatGPT.

It's weaker than ChatGPT and can be wrong. So every answer shows the Wikipedia or WikiMed article it used, and you can read that article yourself. On the right: a real screenshot of Wikipedia's "Bicycle tire" article in the Kiwix reader, Wi-Fi off.

Screen recording to come: the Wi-Fi switched off, then a question asked and answered, start to finish, no cuts.

Why we made it

We noticed how much we ask AI in a day. A recipe, an error message, what a warning light means. Every one of those questions went to a server we'd never see.

Then we read OpenAI's status page. It posts problems most weeks: a feature down, slower answers, more errors. That's normal for an online service. But it meant our answers were only there when their servers were.

Small open AI models now run on an ordinary laptop, so we set one up with Wikipedia beside it. The pieces exist, but they don't fit together on their own. One popular AI runner's Windows installer is about 1.7 GB. Another app's terms forbid bundling it. A well-known offline map app has no official Windows version.

So we picked a set that works together on Windows and Mac, and put it behind one installer. Made in New Zealand.

Everything you'd normally look up, kept on your laptop.

The AI, Wikipedia, WikiMed and a US map pack from OpenStreetMap, chosen to work together with the Wi-Fi off. Pick Essentials, the 1 million most-read articles as text (about 22 to 23 GB in total), or Full, every English article with images (about 133 GB). Both are in the one price.

The full list, with sources and licences

30 minutesto download Essentials on a 100 Mbps line. Full takes about 3 hours.

Set it up in one evening, then turn the Wi-Fi off.

This is the part we do for you. The installer checks your free space, fetches each file from its official source, checks every file against its published checksum and sets up the start page. If the connection drops, it carries on where it stopped.

The first minute

Buy and download

You get the installer, the setup guide and the playbook by email straight away.

The next half hour or so

Run the installer

It fetches Wikipedia and WikiMed from Kiwix's mirrors, the AI from its publisher and your map pack from us. Leave it running.

From then on

Turn the Wi-Fi off

Open the start page. Search, read the map, ask the AI. On Windows or Mac, on laptop battery, with no account.

Your own copy of the answers, for the day the cloud goes quiet.

US$29, once. That's about six weeks of ChatGPT Plus at US$20 a month, except this one you keep. It won't replace ChatGPT. It's the copy that's still yours with the Wi-Fi off. If it's not for you, ask for your money back within 30 days.

Bought once, kept up to date for a year

Wikipedia and the maps change every month. For 12 months we email you when a new tested build is ready, with a one-click update: a newer Wikipedia, fresher maps, and a better local model when a stronger open-licence one runs well on an ordinary laptop. After that, it keeps working exactly as it is.

For power cuts too

Questions people ask first

Isn't all this free online?
Yes, and we credit every source. Wikipedia, WikiMed and OpenStreetMap are open, and you could build this yourself. You're paying for the choosing, the setting up, the testing and 12 months of updates, so it works the moment you need it.
Are you saying AI will go wrong?
No. Nobody knows, and we don't claim to. What we can show is that online AI services have outages and partial problems, posted on their own status pages (more on AI Watch). This is a copy that doesn't depend on them.
How good is the offline AI?
It's a small 4B model, so it's less capable than ChatGPT. It can get facts wrong and sound sure when it's wrong. That's why the Wikipedia or WikiMed article it used sits beside every answer. We'll publish our own test results alongside the model's name.
Do my questions really stay on my laptop?
Yes. The AI runs on your laptop and there's no account, so your questions never leave it. When you're online it checks for updates, and your questions are never part of that.
Do I need to be technical?
No. Run the installer, wait for the download to finish, then open the start page. The setup guide walks you through it with screenshots.
