WhatsApp chatbot for your business

A WhatsApp chatbot answers the messages that customers send to your business number, even when you're not there. In Slimbot, the bot answers from your own knowledge base and website pages, you choose per conversation how much it may do itself, and your team takes over in the same inbox as soon as it's needed.

  • Answers from your own knowledge
  • You choose how autonomous
  • Your team takes over

  • Visitors drop off if there's no immediate reply
  • A standalone chatbot where no one in the team sees the conversations

  • Answers from your own FAQs and knowledge base
  • Every conversation is in the team inbox; you take over whenever you want
  • The same assistant on website chat and WhatsApp

How it works

Get started in 5 steps

From sign-up to working channel. You keep your own number.

1

Sign up and choose number

Start with the Try-out on our test number, or connect your own WhatsApp straight away.

2

Fill knowledge

Services, opening hours and prices you do want to mention. Also have your website indexed.

3

Practise

Simulate customer questions in the practice space and adjust answers. Nothing goes to a customer.

4

Welcome and away message

Switch on the automatic messages you want to use.

5

Live, at your pace

Start with suggestions and only set the bot to automatic when you're satisfied. Conversations land in the inbox.

Features

What you get

Features that Slimbot has today. No promises we don't keep.

Answers from your own knowledge

You fill a knowledge library with frequently asked questions, and Slimbot can index the pages of your website. The bot searches these before it answers.

You choose how autonomous

Per conversation: bot off, only a suggestion for your team member, together, fully automatic, or paused. So you start carefully and give more room when it's going well.

Your team takes over

Conversations are in the shared inbox with a status and an owner. A team member picks up the conversation and the bot takes a step back.

Welcome and away message

Set an automatic welcome message for new contact and an away message for outside your opening hours. Both are off by default and apply per number.

Practise first, then go live

In the practice space you simulate customer chats and give feedback. Those conversations never go to WhatsApp. Only then do you switch the bot on for customers.

Quick replies per number

For questions that your team answers themselves: fixed answers with a shortcut, per WhatsApp number.

Labels and contacts

Give conversations labels, save customer data with the contact and see on the customer card what happened earlier via other channels.

Your own number

Connect your WhatsApp Business app via a QR code, or choose the official WhatsApp Business API in the Business plan.

What is a WhatsApp chatbot?

A WhatsApp chatbot (or WhatsApp bot) is software that automatically responds to messages that customers send to your business via WhatsApp. Simple bots work with fixed buttons and menus. An AI chatbot, like Slimbot's, understands a question in plain language and finds the answer in the information you give it.

The goal is not to hand over your customer contact completely. A good chatbot handles the questions that come up every day, such as opening hours, prices, delivery times and working methods, and leaves the rest to your team, with the question already clearly in view.

Set automatic reply in WhatsApp Business

Many business owners first look for an automatic reply: a message that is sent automatically when someone messages. In Slimbot, these are two separate messages that you write yourself or have the AI writing assistant draft:

  • Welcome message: goes to someone who messages you for the first time.
  • Away message: goes automatically when someone messages outside your opening hours. You set the opening hours in your business profile.
  • Both are off by default, have an example and a live WhatsApp preview, and apply per WhatsApp number.

Chatbot or automatic message: what do you need?

An automatic message is always the same, whatever the customer asks. Useful to let them know when you'll respond, but the customer is still waiting afterwards. A chatbot gives an answer to the question itself. Many businesses use both: during the day the bot or team answers, outside office hours an away message is added.

Building a WhatsApp chatbot without programming

You don't need to write code or draw a flow. You enter your knowledge in Slimbot, have your website indexed and test in the practice space how the bot responds. If an answer isn't right, you adjust the knowledge and try again. Our "setting up a chatbot" guide walks you through the steps.

First set the bot to 'suggest': it will then write a draft that your team member checks and sends. This way you see what it would answer before it sends anything to a customer itself.

What does a WhatsApp chatbot cost?

The chatbot is included in the Slimbot plans; you can see the current amounts below, directly from our price list. If you use the official WhatsApp Business API, WhatsApp additionally charges for outgoing template messages. Replies within 24 hours to a customer who sent you a message are free with WhatsApp.
