Generic AI has never seen your server. Tom AI lives on it.
It fixes problems on one tap, checks its own work, and gets smarter every week from a fleet of real machines — so the answers keep getting better while you do nothing.
Every other “AI help” is a stranger in a chat window guessing from documentation. Tom AI is a mechanic who lives in your garage, has your box's actual service history, and learns from every repair across the whole fleet. It doesn't fix from theory — it fixes from what has provably worked on machines like yours.
Five things a chat window can't do.
It's on your box, not in a chat window.
Tom AI reads your real logs and live container state, tells you what actually broke in plain English, and fixes it on one tap — no copy-pasting error messages into a search bar for three hours.
It checks its own work.
Every fix is verified right after it runs — and automatically undone if it made anything worse. You get a fix, not a gamble.
It fixes from proof, not guesses.
Common problems come with a track record from real SparkBox machines. You're getting the answer the fleet already validated.
It warns you before you break.
Your box quietly checks itself against known issues and tells you — before you ever hit them — when something you're running was already fixed in an update.
It gets smarter every single week.
The whole system learns which fixes actually hold up on real boxes and keeps sharpening — so the support you paid for once keeps improving, for free, forever.
You get the answer the fleet already validated.
Common problems arrive with a track record from real SparkBox machines. Not a plausible-sounding suggestion — a fix with a scoreboard behind it.
And the knowledge travels to your box. Your box's data doesn't get shipped out.
Every battle you fight hardens the whole Fleet.
You're not a customer — you're commander of your own data, flying your own hull. And Tom AI is self-learning: every problem you crush is combat experience the Fleet keeps. Your box wins the fight, the tactic gets sent to HQ, and the whole Fleet comes back harder. The more you throw at it, the stronger we all get.
Your data is the product.
Everything you do gets shipped off, sold, re-identified, and packaged up — so a corporation and the 1% make another dollar off your life. You get nothing back but ads.
Your data works for you.
Nothing is sold, nobody profits off you. Every signal stays sanitized and makes your own Fleet stronger, more resilient, more private — and makes your data more yours, not less.
You win the fight
Tom AI diagnoses, fixes it on your command, and logs the tactic that worked — the battle report, never your data.
The tactic reaches command
Sanitized of every secret and any PII, your battle report flows to HQ — so the same enemy is mapped across the whole Fleet.
The whole Fleet levels up
Tom ships the patch and every hull is immune. That enemy never wins again. Your one bad night armors thousands of boxes.
Your own one-of-one battleship.
Free boxes fly as tiny drones; Legends fly painted warships. Yours is one of 140 hulls in Production Run 1 — recorded in the Fleet Registry, named on its nameplate, and flown by nobody else in the galaxy.

Enlist. Command your own data. Fight Big Tech.
Every Legend is another hull in the line — owning its own data, refusing the cloud, hardening the Fleet with every fight. This is how a scrappy Fleet out-guns the giants: not one big army, but thousands of commanders who never surrender their data.
Enlist as a commander — $99 once ★You've probably already learned from him.
Tom's been teaching people to build exactly this for years — his server tutorials have pulled in over a million views combined. TomSparkBox is all of those videos distilled into one command.
Going Legend keeps this a full-time job.
TomSparkBox is built by one person, full-time — no VC, no ads, nothing sold to advertisers. Every Legend is what makes the next fix, the next app, and Tom AI itself possible. When backing slows, development slows. It isn't a tip jar — it's the fuel.
Two reasons people actually go Legend.
“I paid for Legend to use the AI for help while getting it onto my Linux machine.”
Most people upgrade the moment they're stuck — install day, a cryptic error, a box that won't start. Tom AI is the way out that doesn't involve three hours of searching.
“That worked! What's the best way to support — upgrade to Legend?”
The other half go Legend to keep the project alive: one person builds TomSparkBox full-time, every app stays free, and the $99 is what keeps fixes and updates shipping for everyone.
Tom AI is why you're here. These come with it.
The same $99 upgrades your dashboard to the next-gen GUI — and adds Hearth Chat and My Vault. Free boxes keep the fully-capable classic GUI; Legends get the polished one below. Real screens from a running box:
Your own private chat, on your box.
No accounts, no Big Tech reading your messages, no upload caps — drop a 4 GB video and it just lives on your pool.
Passwords that never touch a cloud.
An encrypted vault that lives only on your box, behind a quick 4-digit PIN — not even the maker's servers ever see it.
If your box dies in a fire, your setup doesn't.
Automated, encrypted backups of your box's configuration to your own cloud storage bucket (Backblaze B2 and friends — typically pennies a month, paid straight to them, never to us). Everything is sealed with a recovery key only you hold before it leaves your box — we couldn't read your backups if we wanted to. Lose the hardware, buy a new box, enter your key: your setup comes back.
Your whole server, in your pocket.
Add SparkBox to your home screen and it opens like a real app — no App Store, nothing to sideload. And when something needs you, your box pings your phone directly — one tap opens Tom AI to look at it and fix it.
How it works — the honest version.
Tom AI works because it sees your real box. Here's exactly what to share and what never leaves.

[REDACTED] insteadOUR SIDE OF THE DEAL
A secret sanitizer strips API keys, passwords, JWTs and key blocks before any message leaves your box.
Sanitized chats stay on purpose — that's how a recurring problem becomes a shipped patch. Never sold, never shared for AI training. Off anytime.
Buy once, get everything we ever ship.
One $99 payment covers every future update and every custom app Tom builds — forever. You're grandfathered in for good.
Straight talk: the $49 beta price ended August 5, 2026. Legend is now $99 one-time — still lifetime, still no subscription, still every future app included. Everyone who bought during beta keeps their price and everything it bought, forever. Whatever you pay today locks in for life the same way.

The questions worth asking.
Is this a subscription? +
No — the $99 is a one-time payment, never charged again for it. The monthly Tom AI message budget resets each month for as long as Tom AI exists. Any optional hosted extras we add later would be separate opt-in purchases, never a charge on what you already bought.
Do I have to pay again for future updates or new apps? +
No. Your one-time $99 covers every future TomSparkBox update and every custom app Tom builds — Hearth Chat and My Vault today, and whatever ships next. Once you're a Legend, you're grandfathered in for good.
Will the price go up? +
It already did — the $49 beta price ended August 5, 2026, and Legend is now $99 one-time. TomSparkBox has grown a lot since we set the beta price — Tom AI, Hearth Chat, My Vault, the new dashboard, the Games module — and our AI costs keep rising. Whatever you pay locks in for life: beta buyers keep their $49 price forever, and $99 is the price we intend to keep. TomSparkBox itself stays free either way.
Does TomSparkBox need a license to work? +
No. TomSparkBox is and stays 100% free — every app, every module. Legend adds Tom AI, My Vault, Hearth, the enhanced dashboard and a cosmetic supporter badge. You can ignore it forever and TomSparkBox keeps working.
Will Tom AI ask for my passwords or API keys? +
No, and the sanitizer actively strips them. Paste an API key, password, JWT, SSH key block or webhook URL by accident and it's redacted before the request leaves your dashboard. The unredacted version never reaches the proxy, the AI, or any storage we control.
Is it refundable? +
Yes — one-time $99, and if it's not for you, message @tomspark on d/sparkbox or email within 14 days for a full refund. TomSparkBox itself is free forever, so you're never paying just to use it.
Can I use Tom AI without backing? +
No — it's the backer perk. It costs real money to run (AI API + proxy + storage); rolling it into 'free for everyone' would mean pulling it or pulling something else free. We keep the free bundle whole and ask the people who want the assistant to fund it.
Where does my chat data go? +
Sanitized chats (no PII, no credentials) live in a diagnostic corpus used to find class-level bugs and ship patches. Never sold, never shared for third-party AI training. Raw history stays local.
