Your AI team, on your own computer.
Give the busywork to AI helpers with a name and a job. They draft, summarise, sort and follow up, on your files and on your schedule. Free, and it works with the Claude or ChatGPT plan you already have.

Helpers with a name and a job. Like a colleague who never forgets.
Set up a helper for each kind of work: a Writer for drafts, a Researcher for facts, an Assistant for the boring admin. Each one remembers how you like things done. They work when you ask, every Monday at 9, or when a new file shows up, and they can pass work to each other.
- Works when you ask, on a schedule, or when a file arrives
- Remembers your preferences between jobs
- Helpers hand work to each other in shared channels
Check in from your phone. Your computer works. Your phone keeps up.
Scan a QR code and your phone becomes a remote. Ask for something, see what’s done and say yes or no to anything that needs your OK, right from the browser. The work still happens on your computer.
- Pair with a QR code, no account needed
- Chat, approve and start jobs from your phone
- At home or at work, on networks you trust
Dashboards you just ask for. Ask a helper, not a spreadsheet.
Ask for an overview and a helper builds it: numbers, charts, tables and to-do lists it keeps up to date. Want it changed? Just say so.
- Numbers, charts, tables and notes in one page
- Kept up to date by the helper that made it
- Right next to your work, one click away
Use the AI you already pay for. No new subscription.
Sign in with your Claude or ChatGPT plan through their official tools, or add Gemini, Copilot and others. Pick a different AI for each helper, and see exactly what each one costs you.
- Works with the Claude and ChatGPT plans you already have
- A different AI for each helper if you like
- See what each helper costs and how long it took
Fast when you want it. A shortcut for everything.
Find any file, helper or conversation in a couple of keystrokes. Every shortcut can be changed, so it fits the way you already work.
- Search everything from one box
- Change any shortcut
- Jump between helpers and conversations
Keep going while it works. No waiting around.
Had another idea while a helper is busy? Type it in. It waits its turn and goes out when the current job is done, or change the job mid-way if plans change. You can still edit or remove anything waiting.
- New requests wait their turn
- Change course while a job is running
- Edit or remove anything that’s waiting
Free on your computer. Every helper, every feature.
The whole app is free: as many helpers as you like, every feature, and your phone as a remote on your own network. The app you download today stays free.

Later, Umbium Cloud will add things that need a server, like helpers that keep working while your laptop is closed, and reaching them from anywhere.
Not available yetQuestions
Is Umbium really free?
Yes. Everything that runs on your computer is free, with no trial and no locked features. When Umbium Cloud launches, you’ll pay only for things that run on our servers.
Do I need my own AI subscription?
Yes, for now. Umbium works with the AI you already use, with your own login: for example your Claude or ChatGPT plan through their official tools, or a key from an AI provider. Umbium doesn’t add a charge on top.
Where does my work go?
Umbium runs on your computer. Your files go only to the AI you choose, just as if you used it directly, plus any connections you add yourself. The app doesn’t track you: no analytics, no crash reports, and it doesn’t check for updates on its own.
Why does Windows or macOS warn me when I install it?
These first versions aren’t signed yet. A signature proves who made an app, and we haven’t bought ours yet. That’s why you’ll see a warning:
- Windows: SmartScreen says “Windows protected your PC”. Click More info, then Run anyway.
- macOS: it says Umbium “can’t be opened” because Apple can’t check it. Open System Settings → Privacy & Security, scroll down, and click Open Anyway next to Umbium. (On older macOS, right-click the app and choose Open.)
- Linux: no warning. Make the AppImage executable, or install the .deb or .rpm.
The warning says Windows and Apple don’t recognise the publisher. It doesn’t mean they found anything wrong. Only download Umbium from umbium.com. Signed builds will come soon.
Can I use it from my phone?
Yes, on your own network. Turn on remote access in Settings and scan the QR code with your phone. The connection isn’t encrypted yet, so only use it on networks you trust, like your home Wi‑Fi. Reaching your computer from anywhere, and the phone apps, come with Umbium Cloud.
What’s Umbium Cloud, and when is it coming?
Optional paid extras that need a server: helpers that keep working while your computer is off, safe access from anywhere, sync between your computers and shared spaces for teams. We’ll announce prices before anything costs money. No date yet.
Which systems are supported?
Windows 10 and 11 (x64), macOS 11 Big Sur or later (Apple Silicon and Intel) and Linux (AppImage, .deb, .rpm, x86_64).
