Chat agent

The AI assistant that answers your customers from what you taught it.

The chat agent is the heart of Central AI: an AI assistant that answers your customers on your website, on Messenger, Instagram and WhatsApp, and through the Chat API, using what you taught it. Every other agent builds on it: the Sales Agent sells through it, the Smart Lead Agent reads its conversations, and the Support Ticket Agent raises tickets from them.

What it does

  • Answers from your knowledge. For each question it looks up the 8 most relevant passages from your knowledge base (documents, CSV files, FAQs, website pages and records you sent through the Knowledge Sync API) and answers from them.
  • Knows what you sell. It reads your offerings (name, description, price and link) when a customer asks about them, even when the Sales Agent is off.
  • Understands the customer’s language. A question in Bangla or another language is translated for the search, so it still finds your English knowledge, and the answer comes back in the customer’s language.
  • Keeps each business separate. It only ever searches your own knowledge; no other business’s data is reachable from your agent.

Turn it on

  1. Add knowledge: upload a document or FAQ CSV, train on your website, or connect the API (Knowledge base).
  2. Open Agent & Chat → Agents in your dashboard and write the agent’s instructions. Its name, welcome message, colours and logo are on Embed & API → Widget.
  3. Try it in the Playground (Agent & Chat → Playground), then put it on your site with the website chat widget or connect Messenger, Instagram and WhatsApp.

What the customer sees

A chat window on your website (or a normal conversation on Messenger, Instagram or WhatsApp) that answers in seconds, remembers the conversation, and, when the Sales Agent is on, shows offering cards with prices and a button to buy, apply, book or register.

Troubleshooting

It says it does not know something that is in my knowledge base.
Check the item finished processing on the Knowledge Base page, and that the wording matches how customers ask. An FAQ with the customer’s own question works best.
It quotes an old price.
Prices come from your offerings when the Sales Agent is on. Update the offering, or the knowledge item that states the price.
It stopped answering.
Check your chat credits under Billing & Usage.
