The agent replies in the customer's language, is instructed never to invent policies, and hands the chat to the team when unsure or asked for a person. - Answers come only from your knowledge base: files up to 20 MB, URLs, sitemaps, plain text, FAQs and products. - The agent replies in the language the customer writes in, including Bangla and Banglish. - When the agent cannot answer, it sends your fallback message or hands the chat to a person, and the team is notified. - After a team member replies, the AI stays out of that chat for 15 minutes. - The agent works inside the shared inbox, with roles, assignment and first-response and resolution time reports. Most support messages are the same twenty questions: delivery time, exchange policy, opening hours, fees, how to reset an account. Answering them by hand ties up your team, and customers who message at midnight wait until morning. SaleMag's AI customer support agent answers those questions from your own documents, in the customer's language, and passes the rest to the people who should handle them. ## What is an AI customer support agent? An AI customer support agent is a chatbot that answers customer questions from a knowledge base the business controls and hands a conversation to a person when it should. In SaleMag it is the [AI chatbot](https://salemag.net/features/ai-chatbot), an [AI agent](https://salemag.net/glossary/ai-agent) running inside your [shared inbox](https://salemag.net/features/shared-inbox) on WhatsApp, Facebook Messenger, Instagram DMs, Telegram and WeChat. It is not a general chatbot that knows "everything". It answers from what you give it, which is what makes it safe to put in front of customers. ## What can an AI support agent learn from? SaleMag's AI customer support agent learns from material you already have: files, web pages, sitemaps, FAQs, plain text and your products. The table shows each source and what it suits. | Source | Good for | |---|---| | Files: PDF, Word, Excel, CSV, TXT, Markdown, JSON (up to 20 MB) | Policies, price lists, course outlines, service menus | | Single web page URLs | A delivery or returns page on your site | | Sitemaps | A whole help centre or website | | FAQs (question and answer pairs) | The exact wording you want for common questions | | Plain text | Opening hours, branch addresses, short notes | | Products | Prices, options and stock from your catalog | When a customer writes, the agent finds the most relevant passages and answers from them. This approach is called [retrieval-augmented generation](https://salemag.net/glossary/retrieval-augmented-generation). A Uttara diagnostic centre, for example, could upload its test list and sample-collection rules, and the agent would answer "fasting lagbe?" from that document. ## How does the AI support agent avoid wrong answers? SaleMag's AI customer support agent is instructed to state facts only from your instructions and knowledge base and never to invent prices, policies, links, phone numbers, dates or availability. When the knowledge base has nothing on the question, it does one of two things, depending on your settings: - sends your fallback message, such as "Let me check with the team", and tells the customer how to reach you, or - hands the chat to a person, if handover when unsure is on. You also set the tone (for example professional or friendly) and write instructions such as "never confirm a refund; pass refund requests to the team". The playground lets you test questions before customers see the bot. ## Does the AI support agent reply in Bangla? Yes. SaleMag's AI customer support agent replies in the language the customer writes in, so a question in Bangla gets a Bangla answer, and [Banglish](https://salemag.net/glossary/banglish) such as "delivery kobe pabo?" gets a reply the customer can read. Bangla FAQs in your knowledge base make the answers sound more natural. ## When does the AI hand a chat to a person? SaleMag's AI customer support agent makes a [human handover](https://salemag.net/glossary/human-handover) when the customer asks for a person, when the question is outside the knowledge base and handover when unsure is on, and, with order taking on, when the chat is about a complaint, a bulk order, a custom request or a change to a placed order. The conversation moves to human mode and your team is notified. While a person owns the chat, the bot does not reply. Agents can switch a conversation back to the bot when they are done. There is also a quiet period. When someone on your team replies in a chat, the AI stays silent there for 15 minutes, even if the chat is still in bot mode. That includes replies sent from the WhatsApp Business app on a number using coexistence. The customer never gets an AI answer on top of a person's reply. ## How does an AI support agent work with a human support team? SaleMag's AI customer support agent works as one member of the team inside the shared inbox, not as a separate tool. The table shows the inbox features your people use alongside it. | Inbox feature | How it helps support | |---|---| | Roles | Moderators see and assign every chat; agents see chats assigned to them or still unassigned | | Assignment and notes | Route a handed-over chat to the right person and leave internal context | | Statuses | Open, pending, resolved and snoozed | | Saved replies | Consistent answers for the questions the AI hands over | | Reports | First-response and resolution time, an agent leaderboard, and AI usage | A practical setup for a Mirpur coaching centre: the AI answers batch times, fees and admission documents from the prospectus; a manager assigns handed-over chats about refunds to the accounts person; and the weekly report shows how quickly the team picks up those chats. ## What can't the AI support agent do? SaleMag's AI customer support agent answers text questions from your knowledge base; it does not take actions such as bookings, payments or refunds. Being specific helps you plan: - It reads text only. Photos and voice notes go to your team. - It does not reply to Facebook or Instagram comments, only to direct messages. - It does not book appointments, take payments or issue refunds. It can collect the question and hand over. - It does not tag contacts or update records by itself. Use the [automation flow builder](https://salemag.net/features/automation-flow-builder) for that. - It can tell customers the status of their recent orders; see the [AI order tracking agent](https://salemag.net/ai-agents/ai-order-tracking-agent). The agent runs on your own OpenAI, Anthropic (Claude) or Google Gemini key, so AI usage is billed to you by the provider. ## Get started Upload your top FAQs and policy documents, create the bot, and test it with last week's real questions.
