Luzia AI Launches Spilo on WhatsApp: What UK Businesses Should Know

The Luzia AI is no longer just a chatbot on WhatsApp. With the launch of Spilo in June 2026, the company is targeting the mess of documents, links, audios and photos scattered across your phone. In this post, I explain what has changed, why Brazil is Luzia's biggest market, and what UK businesses can learn — and apply — from this wave of AI within the messaging app.

TL;DR

• Luzia AI has launched Spilo, an assistant that saves and retrieves information on WhatsApp using natural language.
• Spilo categorises content into up to 10 categories, creates alerts and allows shared lists.
• Luzia has over 50 million users, roughly half in Brazil, and raised $13.5 million led by Prosus.
• For businesses, the message is clear: WhatsApp has become the primary AI interface in Brazil.
• A custom solution via the Official WhatsApp API gives the control that a consumer app cannot offer.

What is Luzia AI and why Brazil leads

Luzia AI was born in Madrid, Spain, in 2023, and grew in an unusual way. Instead of requiring a new app, it installed itself where Brazilians already spend hours each day: WhatsApp. Just save a contact number and chat. This distribution choice explains much of its success.

According to the company, Luzia has already surpassed tens of millions of users worldwide, and Brazil is by far the country that interacts most with the tool. Recent reports mention over 50 million global users, with roughly half in Brazil — a number that helps explain why the startup raised $13.5 million led by Prosus Ventures and opened an office there.

Under the hood, Luzia combines different AI models. The company integrates APIs such as OpenAI's and open models from the Llama family, as well as image generators, choosing the most appropriate model for each type of request: text, summary, image or audio transcription. There are even ready-made commands, like /news, which returns a summary of the day's main events.

For the Agathas Web audience, the most important data is not the hype: it is the behaviour. Brazilian users have already accepted chatting with AI on WhatsApp. This changes the calculation for any company that still treats the app only as a human support channel.

Spilo: Luzia's new bet to organise WhatsApp

On 26 June 2026, Luzia announced Spilo, its most ambitious bet since the original assistant. Spilo is not a chatbot for answering questions — it is a memory tool. The idea: to save, organise and retrieve everything that currently gets lost in screenshots, three-minute audios and links saved in 'notes to self'.

In practice, you send Spilo a recipe link, a meeting audio, a photo of a document or a PDF of a bill. The AI reads the content, understands what it is and archives it intelligently. Later, when you need it, you ask in natural language — 'where is the receipt for the appointment?' — and it finds it.

The content can be accessed both via WhatsApp and through a dedicated Luzia app, for free. It is the same logic that made Luzia AI take off: reduce friction. No one needs to learn a new interface when the entry point is conversation.

The timing of the launch is not random. It responds to a real pain of information overload: we have more data scattered than ability to find it. By positioning Spilo as a 'second brain' accessible via WhatsApp, Luzia extends the time users spend within its ecosystem — and accumulates valuable context over time.

How Spilo organises your information in practice

Spilo's differential lies in three areas. It is worth understanding each, because they show what is possible with AI applied to messaging.

Automatic categorisation into up to 10 categories

All sent content is automatically catalogued into up to ten categories. You do not need to create folders or tag anything: the AI infers whether it is a recipe, a financial document, a travel idea or a task. Over time, Spilo accumulates context and begins to understand your patterns better.

Alerts and commitments

The assistant creates reminders about future meetings or family commitments directly in the messaging app. If you send the audio 'John's appointment on Thursday at 3pm', it turns that into an alert — without opening a calendar, without typing.

Shared lists and collaboration

It is also possible to create shared lists with another person, turning Spilo into a collaborative repository. House shopping list, project materials, event references: everything in one place that both parties access via WhatsApp.

Notice the pattern. None of these functions require the user to learn something new. It is the AI that adapts to human language, not the other way around. This is precisely the principle that separates a good automation project from a digital form disguised as a 'chatbot'. I have already talked about this logic of agents that work for you in the post about AI agents and Gemini Spark for businesses.

Privacy and UK GDPR: the point businesses cannot ignore

When it comes to AI that reads your documents, the obvious question is: where does this data go? Luzia states that information processing is done anonymously and that no personal content saved on the platform is used to train its AI models. The data sent is stored on servers in the European Union.

For the end user, this is a positive signal. For a business, however, the message is more subtle — and important. If Spilo already educates consumers to expect transparency about data usage, any business using AI in customer service needs to offer the same, now under the UK GDPR and the Data Protection Act 2018.

This means being clear about:

• What data is collected in the conversation and for what purpose.
• Where it is stored and for how long.
• Whether and how the content feeds AI models.
• How the customer can request deletion of their own data.

Consumer tools like Luzia AI set the expectation bar. Businesses that automate WhatsApp without a clear data policy will not only risk fines from the ICO — they will sound less trustworthy than a free app. It is a detail that is often left to the end of automation projects and should be at the start.

What Luzia's success reveals about AI on WhatsApp for businesses

The growth of Luzia AI is, above all, a market proof. It shows that users not only tolerate but prefer to solve things by chatting. But there is a huge difference between using a consumer assistant and operating AI within your business.

The table below summarises where each approach makes sense:

Criteria	Consumer assistant (Luzia/Spilo)	Business solution (Official API)
WhatsApp number	Shared / platform's	Own, verified, with your brand
Data control	Defined by platform	Defined by company (UK GDPR)
CRM/ERP integration	No	Yes, custom
Sales and billing automation	Limited	Full, with custom flows
Blocking risk	Depends on platform	Low, within Meta's rules
Cost	Free for user	Investment with measurable ROI

The point is not that Luzia is 'better' or 'worse'. It solves personal life. A business, however, needs its own number, integration with its systems and legal responsibility for every message. That is where an implementation via the Official WhatsApp API comes in — and it is a territory that Agathas Web knows well. I talked about the shift to autonomous agents for businesses in the article about Google I/O 2026 and what changes for UK businesses.

Luzia for business or a custom solution: how to decide

Many people ask whether you can 'use Luzia in the company'. You can experiment, but with clear limits. A consumer assistant is great for personal tasks and for understanding the potential of the technology. It was not designed to represent your brand, integrate with your stock or register an order in your system.

Use Luzia AI — or Spilo — when:

• You want personal productivity (summaries, organisation, ideas).
• You are testing how AI converses before investing.
• No sensitive customer data is involved.

Move to a custom solution via the Official API when:

• WhatsApp is a sales or support channel for the company.
• You need to integrate service, CRM and billing.
• There is volume that justifies automation and metrics.
• Compliance with UK GDPR is mandatory.

The common trap is mixing the two worlds: automating company service on a personal number, without verification, and then getting blocked by Meta. The golden rule is simple: business channel requires business infrastructure.

How Agathas Web puts AI on your business's WhatsApp

At Agathas Web, our reading of the Luzia phenomenon is practical: if millions of users already chat with AI on WhatsApp, your customer is also willing — as long as the experience is good and trustworthy.

We work with the Official WhatsApp API (WhatsApp Business Platform) to build services with a verified number, integration with your systems and custom AI flows. In practice, this allows:

• Answering frequent questions 24/7 with AI, escalating to a human when needed.
• Qualifying leads and recording each contact in your CRM automatically.
• Sending reminders, confirmations and billing within Meta's rules.
• Maintaining a clear data policy, aligned with UK GDPR.

It is the difference between 'having a chatbot' and having an agent that truly works for your funnel. Our own conversational agent platform was born from this demand — and you can see how we think about AI automation for businesses in the article about Gemini Spark, Google's 24/7 AI agent.

The best time to structure this is before the competitor does. The technology has already proven it works; now it needs to be designed for your business.

Conclusion: AI on WhatsApp is no longer a trend

The launch of Spilo confirms a direction that was already clear: Luzia AI has turned WhatsApp into the gateway to AI for the average user. Organising documents, creating alerts and retrieving information through conversation is just the beginning.

For those running a business, the lesson is not to copy Luzia. It is to understand that the customer is already comfortable talking to machines — and to offer, with your own number and data responsibility, an experience that matches that comfort. The technology is mature; the differentiator now is execution.
