How to turn on the AI assistant that replies on its own

SendApp Agent’s AI assistant replies on its own to your customers’ incoming messages, 24 hours a day, in their language, using your knowledge base. It’s set up in a few minutes — often just by giving your website address — and hands over to a human operator when the information genuinely isn’t there.

Before you start

  • A SendApp Agent account
  • Ideally a website or documents to train the AI on

What the AI assistant is

It’s an artificial intelligence that replies automatically to your customers’ incoming messages, 24 hours a day, in their language, using your knowledge base. It’s tied to each Account (the AI identity you create in SendApp): you give the assistant your content and it answers for you on the connected channels, handing over to a human operator when the information genuinely isn’t there.

You give your sources, the AI trains itself and replies on every channel, 24/7.

The 3 ways to train the AI

From a file
Upload a .txt or .pdf document (up to 20 MB): FAQ, price list, product sheets, manual. It’s the most precise source for prices and details.
From a single URL
Paste a web page address and the AI reads it: useful to train it on a specific page (e.g. the pricing page).
From a sitemap / whole site
Give your website address: the AI downloads all the pages, splits them and learns them, with real-time progress. In a few minutes it’s trained on your site.

Turn on the assistant step by step

  1. 1

    Create or open an Account

    The Account is the AI’s identity. In the Account section create a new one (or open the one you want to use). Keep them tidy by product/service: an Account that mixes different topics leads to confused answers.

  2. 2

    Set the base messages

    Define the welcome message, the “I don’t know” message (what it replies when it doesn’t know the answer), any behavior rules (how it should act), the language, the hours, and the option to hand the conversation to a human operator.

  3. 3

    Train the AI

    Upload a file or paste your website or sitemap URL and start: in a few minutes the assistant has learned your content.

  4. 4

    Flip the AI switch on

    Turn the AI switch to “on”: from now on it replies on its own to incoming messages on the connected channels.

Which channels it replies on

The assistant replies on every channel connected to the Account, each with the same knowledge base:

  • WhatsApp (official API) and WhatsApp Web
  • Telegram, Instagram, Messenger
  • Email and SMS
  • Website Widget, Voice and API

When it hands over to an operator

Not everything should be handled by the AI. When the information genuinely isn’t there — or when you decide with a rule or at the customer’s request — the conversation goes to a person: just pause the AI from the switch in the chat and the operator replies. This way the assistant covers 24/7 without ever making answers up.

That’s the whole value: a 24/7 responder that speaks the customer’s language, on your channels, trained on your content, and that knows when to call a person. And it’s set up in a few minutes, often just by giving your website URL.
