Ask anything
The Echo Agent repeats your message together with what the request carried: language, country, device.
Example website
An AI agent right on your site
This page is a stand-in for a builder's website. The chat pill in the corner is the Captain Chat widget running the Echo Agent — a reference agent whose answers come from a builder's server.
Chat without an account (free allowance), or press “Sign in” inside the widget — the sign-in window opens inside the chat, this page never sees your password or session.
What to try
Rich answers
Streaming, buttons, file cards, iframes and widgets — every block type of the agent protocol.
Sign-in request
The agent can ask the visitor to sign in. After sign-in it receives the email and whether it is confirmed.
Install on your site
- Publish an agent in Captain Store and list your site (for example
https://appdock.pro) in the agent's Widget sites. The widget opens only on listed sites. - Add two lines before
</body>:
<script src="https://chat.captain.works/sdk/v1/captain.js"></script>
<script>Captain.init({ agent: "echo-agent", placeholder: "Ask Echo Agent…" });</script>Optional: Captain.open("text") opens the chat with a message (the buttons on this page do exactly that), Captain.close() closes it.
