Custom LLM Integration & RAG Development in Nairobi, Kenya

Internal knowledge assistants that answer from your own documents, and AI features built into your web app using APIs from OpenAI, Anthropic and Google.

Problem Statement

Is your organization's knowledge locked in folders nobody can search?

Policies, manuals, proposals, reports and past contracts are spread across shared drives, email and old systems. Staff ask colleagues the same questions, new hires take months to find their way and good work gets redone because nobody can find the earlier version.

General chatbots don't know your documents and shouldn't be trusted with them casually. A custom LLM integration with retrieval-augmented generation (RAG) answers from your own content, shows its sources and respects who is allowed to see what.

The detail

Custom LLM integration and RAG for your organization

LLM integration means connecting a large language model, the technology behind tools like ChatGPT, Claude and Gemini, to your own systems and data so it can do useful work inside your organization. At Venda Technologies we build custom LLM integrations for Kenyan businesses, NGOs, professional firms and software teams: internal knowledge assistants that answer from your documents, and AI features built directly into your web applications.

Most of these projects rely on retrieval-augmented generation, usually called RAG. Instead of expecting the model to know your policies, RAG searches your documents for the most relevant passages and gives them to the model along with the question. The model writes an answer based on that material and cites where it came from, so users can check it.

What we build

Internal knowledge assistants

A private assistant that staff use to ask questions like "What is our leave policy for contract staff?" or "Which past proposals covered water projects in Kisumu?" and get an answer with links to the source documents. Common sources include HR and finance policies, operating procedures, project reports, product manuals, contracts and past proposals.

AI features inside your web application

For software products and customer portals, we add AI capabilities such as natural-language search, summarization of records, draft generation, classification and structured data extraction. These are built into your existing application, often alongside our web application and portal development work, and use the APIs from OpenAI, Anthropic and Google.

Customer-facing assistants over large content

Where a public assistant needs to search a large library, such as product catalogues or technical documentation, we use the same RAG approach. For simpler FAQ-style needs on your website or WhatsApp, our AI chatbot development service is usually a better fit.

How we build it

  1. Define the questions. We collect real questions your team or users ask and agree what a good answer looks like. This becomes the evaluation set.
  2. Prepare the data. We connect sources such as shared drives, databases or document uploads, clean and split documents into searchable sections and record permissions for each.
  3. Build retrieval. We index content for semantic search, often combined with keyword search, so the system finds the right passages even when users phrase things differently.
  4. Generate grounded answers. The model is instructed to answer only from retrieved material, cite sources and say when the documents do not contain the answer.
  5. Integrate and secure. We add login, role-based access so people only see documents they are allowed to, audit logs and usage limits.
  6. Evaluate and iterate. We run the question set, review failures, and tune retrieval and instructions before and after launch.

Choosing a model and where data goes

OpenAI, Anthropic and Google each offer capable models through business APIs, with different strengths, pricing and data handling terms. Open-source models can also be hosted on infrastructure you control where data requirements are strict, though they need more engineering and hosting effort. We compare options against your use case and design a model-agnostic layer so you can switch providers without rebuilding the application.

Personal data in your documents matters. The Kenya Data Protection Act, 2019 places obligations on organizations to protect personal data, limit its use to legitimate purposes and consider where it is transferred. We help by excluding sensitive documents that don't need to be included, applying access controls, using provider settings that limit data retention and documenting data flows so your data protection officer or legal adviser can review them.

How we measure quality

A RAG system is only useful if people trust it. We track:

  • Whether the right source documents are retrieved for test questions
  • Whether answers are accurate and supported by the cited sources
  • How often the system correctly says it doesn't know
  • User feedback on answers, such as thumbs up or down with comments
  • Response time and cost per query

Common mistakes in LLM projects

  • Skipping data cleanup. Outdated and duplicate documents lead to outdated and conflicting answers.
  • Ignoring permissions. An assistant that shows board papers to every staff member is a serious risk.
  • No evaluation. Without a test set, you can't tell whether a change made things better or worse.
  • Locking into one provider. Models and pricing change quickly; a flexible design protects your investment.
  • Treating answers as final. For legal, medical or financial matters, the assistant should support, not replace, qualified review.

FAQ

Questions about custom llm integration & rag

Can't find your answer? Ask our team — we reply within one business day.

What is RAG and why does it matter?

Retrieval-augmented generation (RAG) searches your own documents for relevant passages and gives them to an AI model when answering a question. It lets the model answer from your up-to-date information, cite sources and avoid relying on general knowledge that may be wrong or outdated for your organization.

How much does a custom LLM integration cost?

It depends on the number and condition of your data sources, access control needs, whether it is a standalone tool or built into your app, and expected usage, which drives AI API and hosting costs. We quote after a discovery call and separate build costs from monthly running costs.

Will our documents be used to train AI models?

Business API offerings from major providers generally state that customer data is not used for model training by default, but terms differ and change, so we review the current terms with you. We also limit what data is sent, configure retention settings where available and consider self-hosted models for stricter needs.

Can the assistant respect who is allowed to see what?

Yes, and it should. We record permissions for each document and filter search results by the user's role before anything reaches the AI model, so staff only get answers drawn from documents they are already allowed to access, and every query is logged.

Which is better: OpenAI, Anthropic Claude or Google Gemini?

Each has strengths, and the best choice depends on your task, language needs, cost and data terms. We test candidates against your own questions rather than relying on general benchmarks, and design the system so you can switch providers later.

How long does it take to build an internal knowledge assistant?

It depends on how many sources you have, how organized the documents are and the permission rules involved. A pilot over one well-organized document set is much quicker than a company-wide rollout. We give a timeline after reviewing your data in discovery.

We hired Venda Technologies to build the new website for Kleography Media, and they completely blew us out of the water. As a media company, our site needed to be highly visual, fast, and capable of handling high-quality content without breaking a sweat.

FAQ

Common questions

Everything you need to know before we start working together.

Do you use pre-made, bought templates for your websites?

Never. We build custom front-end interfaces and CMS architectures from scratch. Most agencies buy a $50 theme, slap your logo on it, and call it a day—resulting in slow, bloated, and easily hacked websites. We engineer scalable, secure platforms tailored exactly to your brand and operational needs.

We don't offer generic "packages" because we don't build generic websites. Costs depend entirely on the complexity of the build—a custom 5-page corporate site requires a different architecture than a multi-vendor e-commerce platform. After our initial discovery call, we provide a transparent, itemized proposal so you know exactly what you are paying for.

For a custom corporate website or brand identity project, our standard turnaround is 4 to 6 weeks. For complex custom portals, Learning Management Systems (LMS), or heavy e-commerce builds with custom API integrations, expect an 8 to 12-week timeline. We map out strict delivery milestones before we begin.

Yes. We don't use clunky manual "Paybill instructions" pages. We build seamless Lipa na M-Pesa STK push integrations (along with Pesapal, Stripe, and PayPal) so your customers can complete transactions instantly without ever leaving your checkout page.

You do. 100%. Once the final invoice is settled, we hand over full administrator access, source files, and asset libraries. We don't hold our clients' digital properties hostage to force them into paying ongoing fees.

Absolutely. While you have the power to update your own content, maintaining the server, updating security patches, and monitoring uptime requires technical expertise. We offer dedicated, monthly maintenance retainers so your site remains lightning-fast and bulletproof long after launch.

No honest agency can guarantee a #1 spot due to Google's constantly changing algorithms. What we do guarantee is best-in-class technical SEO execution, clean code, lightning-fast load times, and data-driven keyword strategies that consistently push our clients to the top of their industries over a 3 to 6-month period.
