On your website
One script tag puts a chat bubble on any page. The conversation runs in an iframe on our domain, so nothing on your site — including session-replay tools — can read it.

AI agents that actually do the work.
Not another chatbot that reads a help page. Zentrum Agents answers from your own documents and acts in your own tools — on your website, out loud, or the moment something happens.

Build it once. Meet people wherever they are.
A published agent serves every channel from the same instructions, the same tools and the same memory. It knows which channel it is on, so it never asks a website visitor for a GitHub link.
Out loud
Talk to the same agent in the browser, with barge-in that stops it mid-sentence when you interrupt. It shares one memory with the text conversation.
Same thread as chat
The moment it happens
A new GitHub issue, an email, a Slack message. The agent reads it, works out what to do, and does it — no one has to be watching.
Runs unattended
Three steps, and none of them are prompt engineering.
- 01
Connect your accounts
Sign in to Gmail, Slack, GitHub, Notion and 250 more through Composio. Your agent uses your own authorised access — we never hold a shared key on your behalf.
- 02
Give it your knowledge
Upload the documents your team already answers from. They are parsed, chunked and embedded, and the agent quotes them instead of guessing.
- 03
Publish it
A published version is frozen. You keep editing the draft, and nothing a customer sees changes until you publish again — so a half-written prompt can never reach live traffic.

The boring parts, done properly.
An agent with access to your inbox and your customers' questions is a serious thing to hand someone. These are the guarantees underneath it.
Three independent layers of isolation
Application scoping, Postgres row level security, and unguessable conversation ids. Any one of them failing is not enough to leak another workspace's data.
Your documents are data, never instructions
Retrieved text is wrapped and labelled as a quotation before the model sees it. A document cannot tell your agent what to do just because someone uploaded it.
A hard ceiling on spend
Usage is metered in credits and the agent stops when they run out. No surprise invoice, and no way for a runaway loop to bill you for it.
The bubble is yours, the transcript is not
The widget's iframe keeps conversations off the host page entirely, which is the only way to keep them out of whatever analytics that page is running.
