Built For WhatsApp Business
Customers message your WhatsApp number at all hours: pricing questions, opening times, order updates, the same handful of things in different words. FastBots is an AI chatbot that connects to your WhatsApp Business number and replies from your own website and documents. Turn on live internet search and it looks things up mid-chat, and with Zapier MCP connected it works like an AI agent that can take real actions in the conversation: book the slot, write the lead into your CRM, raise a ticket. The exact actions depend on which apps you connect.
Providing AI Chatbots to Trusted Brands Around The World
Quick Answers
A WhatsApp chatbot is an AI assistant connected to your WhatsApp Business number that replies to incoming messages automatically. With FastBots, the bot is trained on your website, documents and FAQs, so it answers using your own content rather than generic AI replies.
Yes. Meta requires the number to be registered exclusively for API access, so you'll need a new or unused phone number, not one already linked to the WhatsApp or WhatsApp Business app. Once connected through your Meta Business Account, that number only works through FastBots.
You can build and test a chatbot on the free plan, which includes 1 chatbot and 50 messages per month with no credit card required. WhatsApp connection is included on paid plans starting at $39/month.
Yes, but not as a form. WhatsApp doesn't support the embedded lead form used on the website widget, so FastBots collects details through a short back-and-forth, name, then email, then the question. Those details are stored against the conversation and can be emailed to your team.
Why FastBots
Customers don't wait for opening hours to message. The bot replies the moment a WhatsApp message lands, so enquiries at 11pm don't sit in the inbox until morning.
Point the crawler at your website, upload PDFs, paste in FAQs or sync a Google Sheet. The bot answers from your real prices, policies and service details, not a generic script.
One chatbot, one knowledge base. The answers a customer gets on your website are the same answers they get on WhatsApp, no separate flow to maintain.
The bot can ask for name, email and the nature of the enquiry through a short conversation, then email those details straight to your team so nothing gets buried in WhatsApp.
Connect Zapier or Make for a simple after-the-chat handoff that drops captured leads into a CRM, Google Sheet or email list. Or connect Zapier MCP and the bot can act during the conversation across the apps you link: write the lead into your CRM, raise a support ticket, update a sheet. The actions available depend on what you connect.
If your customers message in French, Spanish, Arabic or Portuguese, the bot replies in the same language. Good for any business with overseas customers or a mixed local market.
Use Tune AI to set the bot's personality, what it should and shouldn't talk about, and a fallback message for anything it can't confidently answer. Keeps replies on-brand.
Turn on live internet search and the assistant looks up fresh information mid-conversation instead of saying it doesn't know. Connect Zapier MCP and it goes further, taking real actions in the chat across the apps you link, such as booking a slot, creating a CRM contact or raising a ticket, rather than only routing captured info afterwards.
Real Scenarios
Cover the same handful of "how much", "do you do this", "what areas" questions that come in overnight, so the morning inbox is shorter.
Answer questions about opening hours, allergens, set menus and reservation policy through your WhatsApp number. Point people at your booking link to finish, or, with a booking app connected via Zapier MCP, let the bot reserve the table right in the chat.
Plumbers, electricians, cleaners and mobile mechanics can quote callout fees, confirm coverage areas and collect job details before a real human follows up.
Sizing, materials, shipping times, returns policy: the bot answers from your store content. For live order lookup, connect your store via Zapier MCP and the bot can fetch order status in the chat; without that it sticks to your trained content.
Reply to listing questions, viewing requests and rental criteria over WhatsApp, then capture the lead's name, number and budget for the agent to call back.
Answer itinerary, pricing and availability questions in the customer's language. Hand off to a real agent for the actual booking, or, with the right app connected via Zapier MCP, let the bot create the booking or hold in the chat.
Reply to enquiries about lesson prices, areas covered, weekend availability and packages, and collect contact details for the instructor to follow up.
Let the bot qualify the enquiry (service needed, location, timing, budget) and email the summary to your sales team before they pick up the phone.

Setup
Paste your domain and FastBots crawls your pages: services, pricing, FAQs, policies. Add PDFs, Google Sheets, YouTube videos or pasted text to fill in anything the website doesn't cover.
House voice
Friendly and practical, like a helpful office manager. Quote prices and service areas from the website only. If a customer asks for an appointment, take their postcode, number and the appliance, then say the team will confirm a time.
In Tune AI, write a short instruction that explains who the bot is, the tone to use, what to answer, and what to pass to a human. Add a fallback message for anything outside its remit.
Open the WhatsApp integration in FastBots, click Continue with Meta, and pick the WhatsApp Business number you want the bot to reply from. Your bot is live on WhatsApp once the number is verified.
Honest Comparison
For most businesses, the WhatsApp inbox is handled three ways: someone manually replies between other jobs, an outsourced answering service takes messages, or enquiries simply sit unread until the next working day. Here's how FastBots fits next to those.
FastBots From $39 / month | Manual Replies Staff time | Outsourced Answering Service $200+ / month | |
|---|---|---|---|
Replies After Hours Evenings, weekends, holidays | Yes, instantly | Only when someone is on | Limited hours, often script-only |
Answers From Your Own Content Prices, policies, services | Yes trained on your site and docs | Yes, if the person knows | Usually generic |
Captures Lead Details Name, email, enquiry | Yes, sent to your inbox | Depends on the person | Yes, as a written message |
Languages Supported Reply in the customer's language | Around 95 | Whatever staff speak | Usually English only |
Push Leads Into Your CRM Through Zapier or Make | Yes, after the chat | Manual copy and paste | -No |
Setup Time From signup to live | Around 30 minutes | Hiring and training | Onboarding call required |
Comparison reflects typical alternatives. Other tools may differ, so always check current pricing and features before deciding.

Got Questions?
The ones we hear most before teams sign up. If yours isn’t here, our support team replies within hours during business days.
No. For the way FastBots works, there are no per-message charges from Meta. Your chatbot only ever replies to messages your customers send in, it never starts a conversation. When a customer messages you first, it opens a 24-hour “customer service window”, and during that window your bot can reply as much as it likes at no charge. Every new message from the customer resets the timer, so an inbound support chat can carry on for as long as they keep replying, and Meta charges nothing for any of it.
Only in one specific case: when a business sends messages first, like marketing promotions or automated notifications. That's a separate use of WhatsApp and it isn't something FastBots does. Your chatbot only ever responds to messages your customers send in, it doesn't send broadcasts or promotions, so the paid side of WhatsApp never comes into play for you.
No, they're completely separate. Your plan's message allowance (for example, the 2,000 responses on the Essential plan) is your usage on the FastBots side: how many replies your bot can send. It has nothing to do with Meta's billing, and the two don't overlap.
No. Your FastBots plan is what you pay, there are no extra Meta charges for normal inbound support. It doesn't cost more the more messages your customers send, either: inbound conversations and your bot's replies stay free no matter the volume.
Yes. Meta requires the number to be registered exclusively for the WhatsApp Business API, so it can't be one already in use on the WhatsApp or WhatsApp Business app. Once it's connected to FastBots, that number only works through FastBots, you won't see chats in the phone app anymore. A common approach is to buy a fresh business SIM specifically for the bot.
If you move an existing number over to the API, the history in the mobile app won't carry across. The workaround is to export your chats first using WhatsApp's "Export Chat" option, or, better, set this up on a new business number from the start.
Not yet. Live chat handover currently works on the website widget on Business plan and above, but WhatsApp handover into the FastBots inbox is still in development. For now, the bot can collect the enquiry and email it to your team so a human can reply directly on WhatsApp.
No, that's a WhatsApp restriction, not a FastBots one. The WhatsApp Business API doesn't support the same embedded forms or buttons. FastBots handles lead capture through a short conversation: "What's your name?" → "What's your email?" → and so on.
Meta provides a "1555" virtual number for WhatsApp Business accounts, but it's not compatible with FastBots. Use a real SIM or mobile number when you set up the integration, otherwise the connection won't work.
Yes. FastBots supports around 95 languages, so if a customer messages in Spanish, French, Arabic or Portuguese, the bot replies in the same language. The underlying answers still come from your trained content, so make sure that content covers what you actually want it to say.
Yes, in two ways. For after-the-chat handoffs, Zapier and Make workflows trigger on chat events such as lead capture and pass details into a CRM or spreadsheet. For live actions during the conversation, connect Zapier MCP and the bot can act across the apps you link, for example creating a CRM contact or raising a ticket, while it's chatting. What it can do depends on which apps you connect.
WhatsApp is included on the Essential plan and above ($39/month). The free plan is great for building and testing the chatbot on your website, but the WhatsApp connection itself sits on the paid plans.
Yes, if you connect a booking or calendar app through Zapier MCP. With that connected, the bot can take the details and book the slot right in the WhatsApp chat. Prefer to keep it simple? The bot can instead capture the booking request (service, preferred day, contact details) and send it to your team to confirm, or point customers at your existing booking link. The actions available depend on which app you connect.
The chatbot itself is usually live in 10–15 minutes once you've pointed it at your site and set the tone. The WhatsApp side takes a bit longer because of Meta's verification: creating the Business Portfolio, verifying the number, confirming via email. Plan for around 30 minutes end-to-end if you have the new phone number ready.
Build the bot on the free plan, then connect WhatsApp when you're ready to take real customer messages.
