Agentic AI, minus the complexity

An AI team that works for you.

Cetonia puts real Claude agents to work in your office: they write, organize, research and ship — while you stay in control. No code required.

For solopreneurs and small teams · macOS, Windows, Linux

Three steps

Delegating has never been this simple.

No intimidating dashboard, no three-hour tutorial.

Create your project

One folder = your business. Cetonia sets up everything else for you.

Hire your team

Pick your agents by their craft — or let Cetonia assemble the ideal team.

Delegate, approve

They work on their own. Sensitive actions go through you before they run.

Skills

Give any agent a new skill.

Equip your agents from a catalog — or paste a GitHub link to install your own. They level up instantly.

Living documents

Your documents are alive — the PDF is just the export.

Everywhere else, you drag dead PDFs into a chatbot. In Cetonia, documents live in The Vault: click a section, say the change, your agent edits it in place — then freeze the result to PDF when it's ready to send.

Done — branded header, maintenance line added, total is now €3,300. Freeze it as a PDF?
Yes, freeze it.

No dead PDFs dragged into a chatbot. Your documents live in The Vault — click a section, say the change, the agent edits it in place. The PDF is just the export.

Document templates

One sentence. A numbered, filed, ready-to-send document.

Invoices, quotes, rent notices, letters — say it in the chat and your agent picks the right template, applies your letterhead, numbers it automatically and files it. Or design your own templates, field by field.

One sentence → the right template, your letterhead, automatic numbering, totals computed, filed in the right folder. Invoices, quotes, rent notices, letters — or templates you design.

Your inbox, handled

Your agent reads the inbox. You just press send.

Connect Gmail: your agent reads what came in, matches the right reply template from your library, fills in the details — and saves it as a draft. Nothing ever leaves without your click.

Hi Nils,

Thanks for the kind words! The full redesign comes to €3,300 — detailed proposal attached.

Happy to walk you and Anna through it this week.

Draft saved to Gmail ✓ nothing is sent without you

Go get Nils' email and answer him.
Reading Gmail... Gmail — 1 email found ✓
Found it — Nils wants a quote for the redesign. I'm drafting a reply from your Quote template, and adding his partner Anna in copy.
Draft's ready in your Gmail — recipients set, proposal attached. You press send.

Ask for a mail — your agent reads Gmail, composes the reply from your template, adds the right recipients, and leaves a draft. You stay the one who hits send.

Connected

Works with the tools you already use.

Your agents act through your own connected accounts — and never without your approval.

Good to know: Cetonia uses your own Claude access (a Claude subscription or an API key). You pay for the orchestration and the interface — not the AI twice.

Questions

Everything people ask us.

Do I need to know how to code?

Never. Cetonia is built for non-technical people: you talk to your agents in plain language, they handle the rest.

Does my data stay with me?

Yes. Cetonia is a desktop app: your projects and files live on your machine, not on a third-party server.

What’s the connection with Claude?

Cetonia orchestrates real Claude agents (Anthropic’s AI) through your own access — a Claude subscription or an API key. You keep control of your AI.
