Your own AI. On your own machine. Forever.

Spark is a complete AI operator that lives on your PC, thinks on your GPU, and never phones home. It's free to download and free to share — hand it to a friend on a drive and it just works.

SUPPORT THE DEVELOPER
$100 once — optional
Spark is free and always will be. If it earns a place on your machine, buy a copy and keep the work going — it's built by one person, and this is what funds the next version. Same software either way; nothing is held back from anyone.

Buy a copy — support the developer
Not today? Take it for free, use it for a month, and please come back if it turned out to be worth it. Checkout by Stripe — we never see your card.
FREE DOWNLOAD · EARLY ACCESS NOW
Free — always
Please download it for free. Early access is open now; the official release lands September 1, 2026. No account, no trial timer, no feature locked behind a paywall.
Please share it peer to peer. Copy it to a USB stick, send it to a friend, seed it to your community. Spark is meant to spread machine to machine — no company server, nothing to shut off.

Sign in once with Google to get the download and your own share link. Free — the sign-up is the update channel: it's how monthly updates and new skill packs reach you. No card, no spam.

The community

Spark owners are a network, not a customer list. New skill packs, tuned models, and upgrades travel peer-to-peer between people for free — the same way the software thinks locally, it improves locally. No account required, no killable download server, nothing that stops working if a company changes its mind.

What's in the box

The operator
A desktop app + command pill. Chat with it, hand it jobs, or let it run scheduled work while you sleep. It reports what it did, and it asks before anything risky.
The minds
Fast mind: a 48-billion-parameter model that answers in seconds on a 12 GB GPU. Deep mind (optional add-on download): a frontier-scale model that streams off your SSD for overnight thinking. Both are open-licensed — yours.
The specs (recommended)
Windows 11 · NVIDIA GPU with 12 GB VRAM (RTX 3060 class or better) · 32 GB RAM · 8-core CPU · ~35 GB disk for the core install (the optional deep mind is a separate, much larger download).
Is it really free?
Yes. Download it, use it, copy it to anyone you like. Buying a copy is a way to support the work, not a way to unlock it.
Do I have to re-download to get updates?
Usually not. Spark updates itself — describe a change and it writes, tests, and installs it on your machine (with automatic rollback if anything breaks), so your copy improves without a download. Community skill packs and upgrades arrive the same way they spread: peer to peer, copied from someone who already has them. A fresh download is only needed when the core minds themselves change — a rare, announced event, never a silent auto-updater.
When is the full release?
Early access is open now; the official release is September 1, 2026. Updates after that are free forever, and they travel peer-to-peer too.
