AI Integration Services
for SaaS, Enterprise & Startups
Brillnex Systems adds AI to your existing product. We connect your software to OpenAI, Anthropic Claude, Google Gemini, or open-source models — and make it production-ready, not just a demo.
As of May 2026, we have delivered AI integrations for SaaS platforms in Australia, the US, and the UK — all at offshore rates from Karachi, with senior engineers who have shipped production AI features, not just tutorials.
TL;DR
AI integration is connecting your existing software to an AI model (GPT-4, Claude, Gemini, or open-source). Brillnex Systems handles the full implementation — API setup, RAG pipelines, prompt engineering, streaming, and production deployment — at offshore rates with a team that has shipped this in real products.
What AI Integration Includes
Every engagement is scoped to your stack and use case. Common deliverables include:
- LLM API integration — OpenAI, Anthropic, Google Gemini, Mistral, Llama
- Retrieval-Augmented Generation (RAG) pipelines over your proprietary data
- AI-powered features: smart search, auto-drafting, summarisation, classification
- Prompt engineering, chain-of-thought orchestration, and model routing
- Vector database setup — Pinecone, pgvector, Weaviate, Qdrant
- Streaming responses, function calling, and tool-use integrations
- Cost optimisation: caching, model fallback chains, token management
- Monitoring and observability for LLM calls in production
Why Hire Brillnex for AI Integration?
Offshore rates, senior engineers
You pay 40–60% less than a US or UK agency. You get engineers who have shipped LLM features in production — not developers learning on your project.
Stack-agnostic
We integrate with any backend (Node, Python, Rails, Laravel, .NET) and any frontend (React, Vue, Angular, Next.js). We work with your existing infrastructure, not against it.
Fast delivery
A basic LLM integration ships in 2–4 weeks. Complex RAG systems take 6–12 weeks. We scope before we start so you know exactly what you're getting and when.
Frequently Asked Questions
What is AI integration?
AI integration means connecting an existing software product to AI models and APIs — so the product can generate content, answer questions, analyse data, or automate decisions using AI. It is the process of adding AI capability to software that was not originally built with AI.
How long does AI integration take?
A straightforward LLM integration (e.g. adding a GPT-4 chatbot to a SaaS product) typically takes 2–4 weeks. A more complex integration involving custom RAG pipelines, fine-tuning, and multi-model orchestration takes 6–12 weeks. Brillnex Systems scopes every project before quoting a timeline.
Which AI models do you integrate?
We integrate OpenAI (GPT-4o, GPT-4 Turbo), Anthropic Claude (Sonnet, Haiku, Opus), Google Gemini, Mistral, Llama 3, and other open-source models via Ollama or Hugging Face. Model selection depends on your use case, latency requirements, and budget.
How much does AI integration cost?
AI integration projects at Brillnex start from $3,000 for a basic LLM feature integration and range to $25,000+ for complex multi-model, multi-system enterprise integrations. Offshore pricing means you get senior engineers at 40–60% less than US or UK agency rates.
Can you integrate AI into an existing SaaS product?
Yes. Most of our integrations are additive — we add AI capabilities to existing products without rebuilding them. We work with any stack: Node.js, Python, Ruby on Rails, Laravel, Django, or .NET backends, and React, Vue, or Angular frontends.
Do you work with US and UK clients from Karachi?
Yes. Brillnex Systems is a Karachi-based AI integration company that works exclusively with international clients — primarily in the US, UK, Australia, and GCC markets. We overlap with US Eastern time for 3–4 hours daily and maintain async communication for the remainder.
