AI development · Brazil

Portuguese-language AI for Brazil's fintech and retail.

Bvyte is an AI and software studio in Ahmedabad that engineers agents, document AI and software for Brazilian companies. Our working language is English, while the assistants we ship read and write Brazilian Portuguese, and the customer journeys are designed around WhatsApp and Pix, with the LGPD in view from the first data map.

Start a project

Pix, WhatsApp and a lot of paperwork

In Brazil a customer can pay instantly by Pix, ask a question on WhatsApp and still be asked for a stack of documents by a back office that works from emails and scans. The gap between how fast customers move and how slowly paperwork moves is where AI earns its place. We build for both sides: the conversation on the phone and the invoice, contract or claim behind it.

Overview

Building AI for Brazil's instant-payment, message-first economy

Brazil moved quickly to instant payments and messaging, and consumers now expect a business to answer on WhatsApp and settle through Pix within minutes. Behind that experience sits a heavy layer of paperwork: tax invoices, contracts, statements and registry documents that staff still read by eye. Companies that join the two layers gain speed where it shows and savings where it counts.

We start from a single journey, such as order status for a retailer or collections for a lender, and build the whole path: the conversation, the payment confirmation and the documents behind it. Portuguese quality is graded by native-speaker reviewers from your team on real chats, and every personal data element is mapped to a legal basis under the LGPD. Because Brazil is eight and a half hours behind us, the work runs asynchronously with a fixed weekly session.

What we build

What Brazilian teams hire Bvyte to build

Portuguese quality, payment rails and tax paperwork decide the outcome, so they come before the model choice.

  1. 01

    WhatsApp sales and support

    Assistants on the WhatsApp Business Platform that answer in Brazilian Portuguese, pass leads to your CRM and hand over to people with full context. See AI chatbot development.

  2. 02

    Pix-aware payment journeys

    Flows that confirm Pix payments, handle expiry and duplicates, and reconcile with orders, through your payment provider's official interfaces.

  3. 03

    Fiscal and commercial document AI

    Notas fiscais, boletos, contracts and bank statements read, validated and matched to your records, with exceptions routed to review. See document AI and automation.

  4. 04

    Agents for finance and operations

    Collections follow-up, supplier queries and reconciliation handled by scoped agents with approvals and logs. See LLM and AI agent development.

  5. 05

    LGPD-aware design

    Legal basis, retention and access request handling designed in, with documentation your encarregado (data protection officer) and counsel can review.

  6. 06

    Software for growing platforms

    Senior engineers for fintech and marketplace products, working in your repositories. See custom software and SaaS.

  • Education

    Enrolment, tuition and student service flows on messaging, with staff dashboards.

Local detail

Brazil specifics we design around

  • Pix first

    Pix instant payments are the default way many customers pay. Confirmation, refund and reconciliation flows are designed around Pix as well as cards and boleto.

  • CPF, CNPJ and NF-e

    People, companies and invoices are identified by CPF, CNPJ and electronic invoices. We build extraction and validation for these formats.

  • WhatsApp as the front door

    Many customers start on WhatsApp, so assistants hand over to a person with the full conversation attached.

  • Tone in Brazilian Portuguese

    Formality varies by region and brand. We agree a tone guide with your team and test against it.

Questions

Frequently asked questions

Still unsure? Ask us directly, a senior engineer replies within one business day.

What is the time difference with Brazil?

India is 8.5 hours ahead of Brasília time. Brazil does not currently use daylight saving, so the gap is stable through the year. Your morning meets our evening, so we plan a standing session then and run the rest through written handovers.

How does the LGPD affect an AI project?

The Lei Geral de Proteção de Dados sets rules on legal basis, purpose, security and data subject rights, and the ANPD is the national authority. We design for minimisation, access and deletion handling, and logging, and we work with your counsel and encarregado on what applies to your case.

Is there AI legislation in Brazil?

A dedicated AI bill has been under discussion in Congress, and we follow its progress without assuming a final form. Meanwhile we apply good practice: transparency, human oversight for consequential decisions and an audit trail.

Does the assistant understand Brazilian Portuguese informal writing?

Current models handle everyday Brazilian Portuguese well, including common abbreviations, but results vary with regional slang and voice-note transcripts. We test on your own chats and add fallbacks for the cases that fail.

Can you integrate with Pix?

Through your bank or payment provider's official interfaces, yes. We design for expiry, duplicates and delayed confirmations, and keep reconciliation separate from the conversation.

Do you work with Brazilian companies that sell abroad?

Yes. Exporters in agribusiness and manufacturing often need bilingual documents and customs paperwork read in Portuguese and English. We build the extraction and review flow for both.

Can you handle voice notes sent on WhatsApp?

We can transcribe voice notes and route them through the same assistant, with confidence checks. Accuracy drops with noise and strong regional accents, so uncertain transcripts go to a person.

Do you work with Brazilian startups as well as enterprises?

Yes. Early-stage teams usually take a fixed-fee pilot, and larger firms a squad that works inside their repositories and review rules.
