When it acts, it says so.
When an answer needs something from another system, it says so — what it did, and how it ended, including when nothing came back to confirm it.
What an action can doCan someone look at order 4471?
I've sent the order number and what you told me to the team. Nothing came back to confirm it, so it's worth checking before you send it again.

What people ask before they try it.
What does the agent answer from?
Only what you give it — pasted text, pages by URL, PDFs and documents, YouTube transcripts, whole blogs imported in bulk, and the lists you keep. It quotes limits and steps from those sources and cites the passage, rather than describing your product from memory.
Every way to add materialWhat happens when the docs don’t cover a question?
It says so, plainly, and offers to pass the question to a person. The visitor leaves an email and the question lands in the agent’s Inbox immediately, whatever your notification settings say — a handoff means someone is stuck right now.
Handing over to a personCan I see what it tried before it handed off?
Yes. Each handoff opens the conversation that produced it, so you reply with the whole context rather than one line. That view is never behind a plan on a Support Agent: a handoff you can’t read has dead-ended, which is the one thing it promises not to do.
Where a handoff came fromDoes it learn from my reply?
A question it couldn’t answer is already waiting in your teach queue. Answer it there and your reply becomes a correction: it wins for that question, and the passage it overruled stops being offered as a source behind that answer.
Teach itHow does it go on my site?
One script tag, copied from the Publish tab, plus a token your own server mints so only your visitors can reach it. The loader drops a frame where you put it and touches nothing else on your page — no framework to clash with, no stylesheet in or out, and nothing fetched until the frame is nearly in view.
EmbeddingWho on my team can read the Inbox?
Anyone you invite into your organisation. They can sign in, open the agent’s Inbox and read every handoff and the conversation behind it. They cannot change its knowledge, voice or rules, publish it, see its token settings, or touch billing — those stay with the account that created it.
Your team can read it, not run itYour customers are asking.
Let hiy answer.
Give your product docs a Support Agent that answers with its source, admits what it can't answer, and hands the unanswered question to your team.
Build your Support AgentAlways labeled as AI, and it may make mistakes — which is exactly why every grounded answer shows its source and every gap is admitted. You say what it covers and how firmly it declines the rest. And you may only twin yourself, or something you own: anything that could be someone else waits for a human. How review works
