RAG development · Brazil
RAG development services in Brazil
Mobile-first products in Spanish or Portuguese, built by senior engineers at cost-effective rates.
Clarigo Infotech builds retrieval-augmented generation (RAG) systems: AI search and assistants that find the right information in your documents, databases and knowledge base, then answer with sources. RAG keeps answers accurate and current without retraining a model, and respects who is allowed to see what.
Brazilian companies most often hire us for fintech, marketplaces and AI automation.

What we build with RAG
Chat with your documents
Ask questions across PDFs, policies, manuals and contracts and get answers with citations.
Enterprise knowledge assistants
One place for staff to find answers across Google Drive, SharePoint, Confluence and more.
Customer support answers
Grounded answers for support teams and chatbots, drawn from your help centre and product data.
Search over structured data
Combine document search with SQL and APIs so answers include live numbers.
Permission-aware retrieval
Users only get answers from content they are allowed to see.
Evaluation and tuning
Test sets that measure retrieval and answer quality, and tuning until they pass.
How we approach RAG development
Why RAG instead of fine-tuning
Fine-tuning changes how a model writes; RAG changes what it knows at the moment it answers. For most business questions RAG is cheaper, easier to update and easier to audit, because every answer points to its source.
Getting retrieval right
Quality depends on how documents are cleaned, split, embedded and searched. We use hybrid search (keyword plus vector), re-ranking and metadata filters, and test retrieval separately from the final answer.
Keeping it current and secure
Connectors keep the index in sync as documents change, and access rules from your source systems are applied at query time so nobody sees what they shouldn't.
Measured, not guessed
We build a test set of real questions with expected answers and track accuracy, citation quality and 'I don't know' rates, so you can see improvement and catch regressions.
Built for Brazilian teams
Time-zone overlap
Brazil is eight and a half hours behind India. We run flexible late shifts for a live daily stand-up in your morning, and work moves forward while you sleep.
Brazil's General Data Protection Law (LGPD)
We design to the LGPD: a legal basis for each use of data, data-subject rights, security controls and data hosted in Brazilian cloud regions when required. We sign NDAs before work starts.
Billing
Invoices in Brazilian reais (BRL) or US dollars. Typical senior rates are $25 to $49 (USD) per hour, or a fixed price for a defined scope.
Industries we work with in Brazil
Brazilian startups and businesses work with us on fintech, marketplace and AI products, with privacy designed to the LGPD and support for Portuguese interfaces.
Agribusiness
Large-scale farms adopt precision agriculture and logistics tools. We build AI agents, assistants and automation around these workflows.
Fintech and banking
Digital banks and Pix reshaped how Brazilians pay. AI here usually means faster reporting, fewer manual steps and better customer replies.
Retail and e-commerce
Mobile shoppers expect instalments and fast checkout. We start with one costly process and automate it end to end.
Mining and energy
Resource companies digitise operations and safety. We build AI agents, assistants and automation around these workflows.
