You do not build it or maintain it
With a flow-builder chatbot you set it up yourself, and when something changes or breaks it is your problem. Here we build it, we run it and we fix it.

Why D·IA
What a regular chatbot will not give you
You ask for changes in plain words
“Add waxing to the services” or “no bookings on Saturdays”: you say it the way you would tell a person, and the change ships tested. No tickets, no developer quotes.
Your own instance
Your data does not sit alongside other businesses on a shared platform. You get your own system and your own database.
Nobody is left without an answer
If the AI goes down, your clients still get a menu holding their real appointments, and most faults are repaired by the system itself.
It keeps getting better, at no extra cost
Every improvement and fix we make reaches every client, tested first in one place and only then released to all. No development bill, and your service never stops for it.
Who it is for
For anyone who works by appointment
If your clients write to ask about times, prices and availability, and somebody has to stop what they are doing to answer, this was built for you. With a calendar, a portal for your clients and a dashboard for you.

What changes
What you get back
Nobody waits for an answer
Your clients write at eleven at night or on a Sunday and get a real answer, with your hours and your services, instead of a voicemail and a wait until Monday.
Fewer empty slots
Every appointment gets a reminder the day before, with one reply to confirm it or move it. A slot that frees up early can be offered to somebody else.
The phone stops running your day
The questions you answer twenty times a week get answered without you. The ones that genuinely need you still reach you.
Nothing for you to maintain
No app to install, no server, no updates and no IT supplier to chase. Running it is our job, and it is part of what you are paying for.
What comes with it
More than answering messages
All of this is already part of D·IA, for you and for your clients.
A portal for each client
Your clients sign in with a code sent by email, no password to remember, and sort out on their own what today turns into a message.
- Book, reschedule and cancel appointments
- Recorded payments, receipts and quotes
- Files and documents
- “Download my data” at any time
Payments, receipts and quotes
Record a payment, issue the receipt or put together a quote with line items from your console, or simply ask the assistant.
- Receipts issued on the spot
- Quotes with line items
- Everything visible to the client in the portal
Privacy taken seriously
Data handling designed for the LGPD, from the portal to the console.
- Clients download their own data
- On request you erase a client completely, and the financial records the law requires you to keep stay pseudonymised
- Your team sees only what its role allows
Compliance requirements specific to healthcare are assessed case by case.
An assistant that learns your business
Over time it knows your business the way someone on your team does.
- Your procedures, preferences and the way you do things
- What it learns on its own waits for your approval
- It never mixes up one client with another
How it works
Three steps, and none of them are yours to build
Managed from end to end.
- Step one
You tell us how you work
Your hours, your services, how you want clients spoken to and what you never want said. One conversation, in plain language. No forms to fill in.
- Step two
We set it up and keep it running
We build your own instance, connect your WhatsApp number and your client portal, and from then on we look after all of it: the system, the updates, the monitoring and the support.
- Step three
Your clients simply use it
They write to the same number as always. You see everything from your console, and you ask for changes in plain language whenever you need one.
Our first client
In production
MIM, live in a medical practice
MIM is the assistant of a medical practice in Brazil, in production since 2026. It is the system this product grew out of.
- Answers on WhatsApp, the patient portal and the doctor’s console
- Appointments, reminders, documents and notices
- Data processed in Brazil, with data handling designed for the LGPD
- Profiles isolated, so a patient reaches only their own records
- Repairs itself and deploys itself, with a no-AI fallback behind it
- Recorded payments, with receipts and quotes as PDFs, from the console and over WhatsAppAvailable in production
- The patient downloads their data from the portal and can ask for erasure; the medical record is kept for the legal period, visible only to the doctorAvailable in production
- The doctor sees and manages what the assistant remembersAvailable in production
No patient data and no usage figures are published here.
Why you can rely on it
Built to keep running without anyone remembering
This is the part you are paying us for and the part you should never have to think about.
Changes without a ticket queue
You ask for the change the way you would tell a person. Before it ships it goes through thousands of automated tests, and if a single one fails nothing ships.
A host that checks itself
Every fifteen minutes it verifies its services, disk, memory, certificates and backups, and repairs what it can without anyone being called.
Alerts that reach us, not you
Alerts reach us on WhatsApp, with email as a backup, and if the server itself stops, a second system notices and brings it back.
Can be rebuilt from scratch
An encrypted backup copy is made every night, and your whole system can be set up again with another provider without losing anything.

Access model
Four profiles, one agent
Each profile is isolated in the database and in the agent itself, not only on the screen. What a profile cannot reach, nobody can talk it into reaching.

Questions
What people ask first
Do I need to understand technology?
No. You tell us how you work, and from then on you use WhatsApp and a console. Everything technical is ours, including the parts that go wrong.
What happens if it goes down?
Your clients still get a menu with their real appointments and documents, and a backup model takes over while the main one is away. Most faults are repaired by the system itself, and the alert comes to us rather than to you.
Is my clients’ data safe?
Your business gets its own instance with its own database, not a shared one. Each profile is isolated, so a client only ever reaches their own records, and your team sees only what its role allows. Data handling is designed for the LGPD: a client can download their own data and, on request, be erased completely. Compliance requirements specific to healthcare are assessed case by case.
How long until it is working?
That depends on how much you want it to handle. We work it out in the first conversation and tell you honestly, rather than print a number here that would not apply to you.
When the product improves, do I pay more?
No. Every improvement and fix reaches every client, tested first and then released to all, with no extra cost and without stopping your service.
Let us look at your diary together
A first conversation takes half an hour and costs nothing. You will know quickly whether this fits the way you work, and we will tell you if it does not.
