Works with your inbox, your website, and your systems.
On day one Celeste answers from your own knowledge. Connect the channels your customers already use, then the systems your team runs on when you're ready, and the agent can look things up and act on them, all inside limits you set. The customer gets it handled in the first reply.
Where your customers already reach you.
Connect a shared mailbox with a secure sign in, and Celeste starts watching within about a minute. Replies land right in the thread, so it reads like your team.
One line of embed code. Visitors ask Celeste anything, and the agent hands off cleanly to a person when they need one.
We only list channels that are live today.
Give Celeste your tools, and the work actually gets done.
The agent works fine without any of this. But connect your order system or your billing tool and Celeste can look up the order, check whether it qualifies, and issue the refund, then reply with it already sorted.
No app catalog to wait on
There's no fixed list of supported platforms. If your system has an API, Celeste can work with it, without waiting for us to build a connector.
Any REST API
Hand Celeste an API with its OpenAPI spec and the agent works out the operations and turns them into tools.
MCP servers
Point Celeste at a Model Context Protocol server your developers built, for your own internal systems.
A lookup URL
For a quick one-off lookup, a single endpoint is enough. No rebuild required.
Powerful tools, on a short leash.
An AI that can move money needs more than good intentions. Every tool Celeste touches runs inside guardrails you set, enforced in real code.
You choose what it can touch
Every tool is off until you switch it on. You decide, category by category, what Celeste is allowed to reach.
Risk is set, not guessed
You mark how risky each action is. Anything risky you haven't classified is held for a person, every single time.
Hard limits on every action
Amount caps and conditions like "only within thirty days" or "ask me first over two hundred dollars" are enforced in code, however confident the agent is.
Only the customer in front of it
A lookup is scoped to that one customer's own records. Celeste can't pull up someone else's order, even by accident.
Your keys stay yours
Connected tools get short-lived, scoped tokens, never your real credentials. And whatever a tool sends back is treated as untrusted.
Put Celeste to work in the tools you already run.
Start a free trial and connect the channel you already use. Celeste learns from your own data and practices in private, and nothing reaches a customer until you say so. No card to begin.
