What is an AI assistant on WhatsApp?
It is an assistant built for the business number: it reads the question however it is written, works from the business content and the calendar, and what it does is in the written scope agreed at setup. The setup and the operation are ours, and it works on the WhatsApp you already use.
What is the difference between an automated menu and an AI assistant?
The automated menu only accepts the option it offers itself: whoever writes “any slot on Thursday afternoon?” gets stuck or gives up. A custom assistant works from the sentence however it is written: it looks for the free slot, shows the options and records the request. It is the difference between a fixed list and a design made for your service.
How much does an AI assistant on WhatsApp cost?
From $400 per month on the annual plan, with no setup fee. On the monthly plan the fee is $500, $800 or $1,050 by volume, plus the Meta charge per message. On the annual plan, with the 12 months paid upfront, the monthly fee drops 20% to $400, $640 or $840, and there is no setup fee. The AI spend sits inside the monthly fee; the only amount outside it is the Meta message. Above the month volume, each extra assistant message costs $0.19, sold only in a pack of 2,500 for $475.
How do I cut no shows in the clinic or the salon?
By confirming and reminding at three moments: 72 hours, 24 hours and 2 hours before the time. That is what the assistant does on every booking, and a confirmed slot is a slot that does not stay empty.
What happens to WhatsApp outside business hours?
A conversation that arrives after hours is not lost: it is recorded and joins the queue with its arrival time, and what the assistant does with it is in the written scope agreed at setup. When the case needs a person, it hands over and leaves the record for the next day.
Does it work for dentists, salons, shops and real estate?
It works for whoever books slots or sells on WhatsApp: clinic and practice, salon and barber, shop, real estate broker, insurance broker, solo professional and small team. The design is the same, and what changes is the vocabulary of the stages, which we adjust to your case.
How do I start using the assistant?
After you subscribe, our team gets in touch to set up the service with you, on the same WhatsApp number you already use.
Do I need a booking system to start?
No. In the setup we organize hours, services and prices, and that is what the assistant uses to offer the free slot. The calendar that goes into the setup is the assistant one. If you already use a system with an open integration, such as iClinic, Feegow or Doctoralia, linking one to the other is a separate service, assessed together.
How do we know it is working?
From the record: how many conversations the assistant handled, how many slots were confirmed and how many times it handed over to a person. The hourly summary sits in the panel, and the reading is yours.
Is it worth more than a subscription chatbot?
The subscription one is usually monthly, the same for everyone, with a ready menu and no calendar, no file and no operation with people behind it. Here there is no setup fee. The design is that of your service. If your case is only answering the same question over and over, we say so before selling, because the ready one solves it.
Who is Vexor?
Vexor builds and runs custom AI assistants on WhatsApp, for small and medium businesses in Brazil.
How long until it is live?
We set everything up, and the assistant goes live within 1 business day of receiving the information. Without the dedicated number and the content, the clock does not start. From that point on, adjustments are weekly, from what the conversations show.
Who takes care of it when it breaks?
We do. The operation is ours, with monitoring and tuning.
Where does the data live?
The conversation lives on the business WhatsApp, which is the primary source, and the record is stored in the Vexor system, with a full export when you leave.
Can I cancel?
Yes. Cancellation is requested through the WhatsApp where the purchase was handled. On the monthly plan, with 30 days notice. On the annual plan the contract runs for 12 months with upfront payment. Withdrawing within 7 days, we refund the full amount paid. Cancelling between day 8 and day 30, we refund the amount paid minus the days used. After day 30 the contract runs to the end of the 12 months, with no refund.
Do I take my data with me if I leave?
You do. Calendar, contacts and conversation history are yours, and the export is part of leaving.
Which WhatsApp number does the assistant use?
A number dedicated to the business, connected through the official Meta API, which is our default. You are responsible for the number. A QR code connection carries a risk of being blocked, so we do not use it by default.
What is not included?
The per message charge from Meta, which is passed on and shown in the price. Connecting the assistant to a booking system you already use, which is a separate service. The business content, which comes from you, since outdated material leads to wrong guidance.
What changes between the Small, Medium and Large tiers?
The assistant is the same in all three tiers, and what changes is the volume: up to 1,000, 2,000 or 3,000 conversations per month. Large includes 2 WhatsApp numbers; Small and Medium, 1. With a $150 ticket, 3 recovered appointments in a month pay for the Small plan.
What counts as a conversation?
Every conversation on the number counts as one, from the first hello until the matter is closed. If the same person writes again on the same day, it is still the same conversation.
What happens if we go over the month volume?
Above 1,000, 2,000 or 3,000 conversations per month, depending on the tier, each extra assistant message costs $0.19 per message, sold only in a pack of 2,500 messages for $475 (never a single message) and charged on the next invoice. The warning arrives when the volume passes 80% of the contracted one, so there is no surprise at the close of the month. Each tier also has a usage safety limit, with headroom over the volume: if the assistant reaches it, we warn and it pauses until the next month, with no extra charge.
What if our volume is bigger than the Large plan?
More than 3,000 conversations a month? We build a tier for your volume, agreed in writing before we start.
How much does Meta charge for the messages?
$0.0034 per delivered message, apart from the monthly fee, with a price per category and per country. Service and utility have one price, marketing costs more. The value per country is public in the Meta pricing documentation and in the WhatsApp Business Platform pricing table (whatsappbusiness.com/products/platform-pricing).
How much does media storage cost?
Media (photos, audio and files) is an add-on in packs, with no setup: 5 GB for $48.00 a year, 25 GB for $115.20 a year and 100 GB for $278.40 a year.

The proof is the assistant itself, already live: you can talk to it with nothing to schedule.
- It follows the business hours agreed at setup.
- It offers only a slot that exists in the calendar.
- It hands over to a person when you ask.
The proof is you trying it now. Chat with the demo assistant and check the service before you decide.
