RAG development · Johannesburg
RAG development services in Johannesburg
Mobile-first, low-bandwidth products with mobile money built in, from a senior team on overlapping 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.
South African companies most often hire us for fintech, healthcare software 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.
Remote, but close to Johannesburg
Time-zone overlap
South Africa is three and a half hours behind India, so our working days overlap for most of your morning and early afternoon.
The Protection of Personal Information Act (POPIA)
We design to POPIA's conditions for lawful processing: purpose limits, security safeguards and data-subject access, with data hosted in South African cloud regions when required. We sign NDAs before work starts.
Billing
Invoices in South African rand (ZAR) or US dollars. Typical senior rates are $25 to $49 (USD) per hour, or a fixed price for a defined scope.
Where we help Johannesburg businesses most
Johannesburg and Sandton companies in finance and insurance use us for platforms, integrations and AI automation, designed to POPIA.
Mining
Mines invest in safety, monitoring and automation systems. We start with one costly process and automate it end to end.
Financial services
Banks and insurers lead in mobile and digital channels. We build AI agents, assistants and automation around these workflows.
Retail
National chains expand e-commerce and loyalty programmes. AI here usually means faster reporting, fewer manual steps and better customer replies.
Tourism and wine
Operators and estates sell to international visitors online. We start with one costly process and automate it end to end.
