WA Auto Responder & Chatbot Offline — Rule-Based WhatsApp Automation

What is an offline WhatsApp chatbot?

An offline chatbot uses predefined rules — not artificial intelligence — to respond to incoming WhatsApp messages. When a customer types a keyword like "price" or "support", WhatSender Pro matches the trigger and sends the exact reply you configured. No API keys, no token costs, no dependency on external AI services.

This is different from online AI agents (GPT-4, Claude, Gemini) which generate dynamic answers. Offline bots are faster, cheaper, and fully predictable — perfect for compliance-sensitive industries, high-volume FAQ shops, and businesses that want 24/7 coverage without monthly AI bills.

How to set up your WA auto responder

  1. 01

    Open the Offline Chatbot builder

    In WhatSender Pro Business Edition, go to Tools → Offline Chatbot → New Flow. The visual flow editor lets you design decision trees without coding.

  2. 02

    Create keyword triggers

    Map keywords to responses: “price” → pricing message, “hours” → business hours, “catalog” → product PDF. You can set multiple keywords per flow and case-insensitive matching.

  3. 03

    Build nested menus

    Create multi-level menus: “Reply MENU for options” → “Press 1 for Sales, 2 for Support, 3 for Billing”. Each branch can lead to another sub-menu or a final answer.

  4. 04

    Attach media replies

    Send a PDF price list, product image, or location map when a keyword matches. Media replies make the bot feel professional and reduce back-and-forth.

  5. 05

    Set a fallback message

    When no keyword matches, send: “Reply MENU to see options” or route to a human agent keyword like “agent”. This prevents silent failures.

  6. 06

    Activate auto-reply on your account

    Toggle Auto Reply ON for the connected WhatsApp number. The bot runs in the background — every inbound message is checked against your rules instantly.

  • Keep each reply under 3 short paragraphs for readability on WhatsApp.
  • Add a welcome message for first-time contacts with your main menu.
  • Monitor unmatched messages weekly and add new keyword triggers.
  • Combine offline bot for FAQs with online AI for complex follow-up questions.
