RAG development · Portugal
RAG development services in Portugal
GDPR-first, fully documented and hosted in the EU, with a senior team working your morning hours.
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.
Portuguese companies most often hire us for SaaS products, startups and AI automation.

Privacy, quality and clear documentation
European teams tell us they want a partner who treats data protection and quality as the starting point, not an add-on. That is how we work.
GDPR by design
Data minimisation, consent, EU hosting and a signed data processing agreement before any personal data is touched.
Documentation you can audit
Written specifications, architecture notes, test reports and handover documents, so your team or auditors can follow every decision.
Accessible by default
Interfaces built to WCAG guidelines, helping you meet the European Accessibility Act for digital products and services.
Predictable contracts
Fixed scope and price, clear milestones and acceptance criteria, and full ownership of the code and IP.
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.
Remote, but close to Portugal
Time-zone overlap
Portuguese and Indian working days overlap by four and a half to five and a half hours, so stand-ups, calls and quick decisions happen during your morning and early afternoon.
The GDPR and Portugal's Law 58/2019
We design to the GDPR and Law 58/2019: data minimisation, consent, access controls, encryption, EU hosting and a data processing agreement signed before work starts.
Billing
Invoices in euros (EUR) or US dollars. Typical senior rates are $25 to $49 (USD) per hour, or a fixed price for a defined scope.
Built for Portugal's key sectors
Portuguese startups and scale-ups in Lisbon and Porto use us for SaaS products and AI, with senior engineers who work alongside your own team.
Tourism
Hotels and short-term rentals compete for international guests. AI here usually means faster reporting, fewer manual steps and better customer replies.
Tech startups
Lisbon and Porto hubs attract product companies. We start with one costly process and automate it end to end.
Wine and cork
Producers market and export through digital channels. We build AI agents, assistants and automation around these workflows.
Textiles and footwear
Manufacturers build direct-to-consumer brands. AI here usually means faster reporting, fewer manual steps and better customer replies.
