Building a 100% Free On-Prem RAG System with Open Source LLMs, Embeddings, Pinecone, and n8n After the last post on building a financial statement analyzer using OpenAI and n8n, many readers reached out with a common question: “Can I build a similar RAG system without relying on OpenAI APIs or paid cloud services?” The answer is — yes, absolutely. In this tutorial, I’ll walk you through building a complete Retrieval-Augmented Generation (RAG) system entirely on-prem , using free and open-source tools . No API keys, no vendor lock-in, and no code required. With the help of: n8n for orchestrating your workflow Pinecone as a vector database (free-tier available) Ollama for running open-source LLMs and embedding models locally Windows Command Prompt for setup and automation You’ll create a fully functional RAG pipeline that: Accepts documents Converts them to embeddings Stores and retrieves relevant context Answers user queries intelligently — all fro...

Building a Financial Statement Analyzer in 15 Minutes Using AI Agents, n8n & GPT-4o From Concepts to Code: Our First Hands-On GenAI Project As I mentioned at the start of this blog series, this space isn't just for high-level ideas and industry perspectives — it's also a place to roll up our sleeves and build. While the last few posts explored theoretical foundations, ethical considerations, and strategic frameworks around GenAI, it’s time to mix things up with something a bit more hands-on. Starting this week, I’ll be sharing a few mini-projects — simple yet meaningful applications of Generative AI. These are designed to help you: Get comfortable with GenAI APIs and tools See real-world implementation patterns Learn by doing — not just reading Build your confidence to take on larger, domain-specific use cases Here’s the first project to kick things off  Financial data analysis is often manual, time-consuming, and error-prone. So I challenged myself: ...

Risks, Ethics & Governance in the Age of GenAI With great power comes even greater responsibility. We’ve explored the tremendous promise of Generative AI — how it’s reshaping business models, accelerating innovation, and amplifying human creativity in ways once unimaginable. But as with any powerful technology, GenAI brings with it a shadow side — a complex web of risks, ethical dilemmas, and governance challenges that can no longer be considered optional side notes. They must move to the center of the conversation. These challenges aren’t just hypothetical or futuristic. They are real, growing, and already impacting society in subtle and sometimes profound ways. While much has been written and discussed about the legal, regulatory, and economic frameworks surrounding AI, this post aims to zoom in on something more fundamental and immediate : The ethical and social consequences of widespread GenAI adoption — and our collective responsibility in shaping how this technol...

04 - How Business Ecosystems Are Transforming with GenAI

Image
How Business Ecosystems Are Transforming with GenAI The rise of Generative AI isn’t just another wave of digital transformation. It’s a paradigm shift — one that is redefining not only what technology can do, but how businesses think, operate, and evolve. From strategic boardroom discussions to real-time customer interactions, GenAI is reshaping every layer of the enterprise. It’s enabling organizations to: Invent new products that were previously unimaginable Reimagine services with unprecedented levels of personalization     Redesign experiences that feel natural, responsive, and intelligent In essence, GenAI is becoming the co-pilot of business innovation — augmenting creativity, accelerating decision-making, and unlocking efficiencies across the value chain. But Transformation Isn’t One-Size-Fits-All Despite the rapid momentum, adopting GenAI meaningfully isn't about blindly deploying the latest tools. Success depends on thoughtful alignment with bu...
