RAG development · Berlin

RAG development services in Berlin

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.

German companies most often hire us for enterprise software, manufacturing and Industry 4.0 solutions, and GDPR-compliant AI.

What matters to Berlin teams

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.

01

GDPR by design

Data minimisation, consent, EU hosting and a signed data processing agreement before any personal data is touched.

02

Documentation you can audit

Written specifications, architecture notes, test reports and handover documents, so your team or auditors can follow every decision.

03

Accessible by default

Interfaces built to WCAG guidelines, helping you meet the European Accessibility Act for digital products and services.

04

Predictable contracts

Fixed scope and price, clear milestones and acceptance criteria, and full ownership of the code and IP.

What we do

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.

In depth

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.

Time-zone overlap

Central European and Indian working days overlap by three and a half to four and a half hours, so your team is online for stand-ups and calls every morning your time.

The GDPR and the German Federal Data Protection Act (BDSG)

We design to the GDPR and BDSG: data minimisation, clear consent, access controls, encryption, data hosted in Germany or the EU, and a data processing agreement (AVV) signed before work starts.

Built for Berlin's key sectors

Berlin startups use us for SaaS MVPs, AI products and senior engineering capacity, built to the GDPR with data hosted in Germany or the EU.

Automotive

Carmakers and suppliers shift to software-defined vehicles. AI here usually means faster reporting, fewer manual steps and better customer replies.

Industrial manufacturing

Mittelstand firms adopt Industry 4.0 and predictive maintenance. We start with one costly process and automate it end to end.

Mechanical engineering

Machine builders add IoT portals and digital services. We build AI agents, assistants and automation around these workflows.

RAG is a way of building AI assistants that first search your own documents and data for relevant information, then use a language model to answer from what was found, usually with citations.

How is RAG different from a normal chatbot?+

A normal chatbot answers from what the model learned in training. A RAG assistant answers from your current, private information, so it is more accurate for your business and can show its sources.
