Single home for your agenda, messages and inbox.
The Personal
Operating System.
It remembers, so you don't have to.
Apps run on an operating system
Your agent runs on Zaelar.
Not a chatbot. Not another assistant. The calm, always-on layer where your personal AI lives.
- Persistent memory that actually remembers.
- One home for your agenda, messages and inbox.
- Long-term context that never resets.
Why a Personal Operating System
Every layer of computing got an OS.
Your personal AI deserves one too.
An operating system doesn't do the work for you — it's where the work happens. Zaelar is where your agent builds it.
| Before | With Zaelar |
|---|---|
| You opened a different app for every task | You say what you need; your agent builds the workspace |
| Every app kept its own data, on its own | Your data and context live in one place, with your agent |
| Isolated tools, no memory between them | One agent, many tasks handled underneath, one result at a time |
Zaelar is not an AI assistant, an LLM wrapper, or "one more chatbot." It's the operating system underneath your agent.
Your agent
Your agent. Your name for it.
Call it Harvey, Susan, or anything you like. It learns you, remembers, and gets things done — across your agenda, messages and inbox.
You build the relationship with your agent. Zaelar is the home it lives in — always on, always in context. Name it once; it's yours.
How Zaelar works
Set it up once. It works from then on.
Bring your world in.
Connect your apps, messages and accounts — securely.
Meet your agent.
Give it a name. It learns you and remembers.
It just runs.
In the background, across devices — quietly working for you.

FAQ
Questions, answered calmly.
What is Zaelar?
A Personal Operating System — one place where your agent lives, remembers, and acts for your digital life. It's not a chatbot or an assistant app; it's the layer it runs on.
So Zaelar isn't the assistant?
Right. Your agent is who you talk to — you give it a name (Harvey, Susan, or your own). Zaelar is the operating system that hosts it.
Is it free?
The software is open source and free to self-host, forever. Zaelar Cloud — the fully managed version — starts at €9.99/month.
What am I paying for?
Convenience, not hosting. The €9.99 base covers your cloud account, storage, automatic updates, encrypted backups and sync. The AI compute your agent uses is paid separately as Energy — because you're really paying for the external AI, not for Zaelar.
What are Energy Capsules?
Recharges for the AI compute your agent consumes. Your plan includes monthly Energy; when you need more, you top up (€10–€500). Energy never expires, and if you run out, Zaelar simply eases off with a heads-up — never a surprise bill.
Can I run it myself?
Yes. Zaelar is open source — clone it, bring your own AI keys, and run it anywhere. You'll handle setup, updates, backups and uptime yourself.
Why choose Cloud if self-hosting is free?
Because self-hosting well means running a server 24/7, keeping it updated, backed up and secure. Cloud does all of that for you and stays continuously up to date. When something breaks, we lose sleep — not you.
Is my data private?
Yes. Your data lives in your own space — isolated, encrypted and portable. Because Zaelar is open source, anyone can verify exactly what runs on your data. You can leave and self-host anytime. No lock-in.
When can I use it?
Zaelar Cloud is rolling out to a whitelist in small batches. Request early access — or self-host today.
