Little jobs it does all day long
As easy as plugging in a lamp.
No installing. No accounts. No settings to figure out. If you can open a folder, you can use Think Stick.
Plug it in
Put the Think Stick into any USB port on your computer, just like a photo drive.
Double-click Start
Open the drive and double-click “Start Think Stick.” A chat window opens in your browser by itself.
Say hello
Type a question, drop in a photo, or just talk. Your AI is awake — and it never phones home.
The very first launch takes a few extra minutes while your stick sets itself up. After that, most computers are ready to chat in about a minute. If replies ever feel slow, one setting lets you switch to a lighter AI — in plain language, no jargon.
Try a real conversation.
Pick an example and watch how Think Stick handles everyday jobs — from the kitchen table to the toolbox.

One little stick. A lot of help.
Everything below runs on your computer, from the stick — not on someone else’s servers.
Real conversation
Ask questions, brainstorm, write, plan, and learn. Choose Short, Medium, or Long answers with one click — no settings maze.
Understands your photos
Drop in up to four pictures per message. It can describe what it sees, read clear text, compare images, and explain screenshots.
It won’t make safety calls about plants, food, medicine, or injuries — on purpose.Reads your documents
Import whole folders as collections, search hundreds of PDFs as you type, and tap any citation to see the exact page it came from. Scanned pages work too, and a reference library comes ready to search.
Speaks and listens
Talk hands-free or push-to-talk, and hear replies in one of twelve natural voices. Interrupt it mid-sentence just by speaking — like a real conversation.
Your phone works too
Scan a QR code and chat — or talk — from your phone over your own Wi-Fi. You can even snap a photo of a paper page and it joins your library.
Remembers what matters
Tell it your names, your cars, your garden — once. It keeps one small memory file on the stick, uses it in every reply, and you can read or erase every word.
Reads out loud
Any answer or document page can be read to you in one of twelve natural voices, at the speed you like. Hands busy? Just listen.
Still a USB drive
Keep any files you like in the My Files folder — vacation photos, tax PDFs, anything. It shows up in the app and in your computer’s file manager alike.
Fits the computer it’s in
Think Stick checks your computer’s memory and quietly picks the AI brain that runs best on it. Two sizes are included — you never have to choose.

Not mockups — three short films of the software that ships on every stick. Tap the speaker for sound.
What happens on the stick, stays on the stick.
Most AI assistants send every word you type to a data center. Think Stick doesn’t. The AI itself lives on the drive and does its thinking right on your computer — your conversations are stored on your stick, under your control.
Unplug it, and everything — the AI, your chats, your photos, your documents — goes with you. Plug it into another computer, and it’s all still there.

Things people ask us.
Do I need to know anything about AI to use this?
No — that’s the whole point. There are no models to pick, no settings to configure, and no jargon. You plug it in, double-click Start, and type like you’re texting a knowledgeable friend. Think Stick quietly handles all the technical decisions behind the scenes.
Does it really work without internet?
Yes. The AI itself is stored on the stick and does its thinking on your computer, so normal use needs no connection at all. The only times it goes online are the moments you explicitly ask for — an optional repair, or an update you start yourself in Settings — and even then it only downloads. It never uploads your conversations.
Will it run on my computer?
Think Stick needs a 64-bit Windows 10/11 computer or a Mac with at least 12 GB of memory (RAM) — and 16 GB or more runs its strongest AI and gives the best answers, especially from your documents. Checking takes ten seconds: on Windows, right-click Start and choose System, then look for "Installed RAM"; on a Mac, open the Apple menu and choose About This Mac. Full walkthrough: Will it run on my computer? Not sure? Our 30-day money-back guarantee means you can simply try it.
Is it as smart as ChatGPT?
We’ll be straight with you: no. Cloud AI runs on warehouse-sized computers; Think Stick runs on yours. It’s genuinely good at everyday jobs — writing, summarizing, photos, documents, conversation — and like any AI, it can be wrong. What you get in exchange is something cloud AI can’t offer: conversations that never leave your computer, no subscription, and an AI you actually own.
Give someone a little genius.
One stick. No account, no subscription, no cloud — just a helpful AI that belongs to you. Ships free, with a 30-day money-back guarantee.
