Where do beginners start?

AI Essentials for Work, then Microsoft 365 Copilot or Prompt Engineering.

Not for AI Essentials or the Copilot courses. The n8n and LangChain courses are more technical and assume some comfort with code.

Which tools are covered?

ChatGPT, Claude, Gemini, Microsoft 365 Copilot, Copilot Studio, n8n and LangChain.

Is it free, and is there a certificate?

Every lesson, note and assessment is free. The EDWartens certificate is optional and paid, and you can finish without it.

AI Essentials for Work: ChatGPT, Claude, Gemini and Copilot

Use ChatGPT, Claude, Gemini and Copilot properly at work: what they are, how to ask, how to check what comes back, and what never to paste in. Taught from Google's AI Essentials, Anthropic's AI Fluency course and OpenAI Academy.

Decide which tasks to hand to an AI assistant and which to keep
Write prompts with a task, context, references and format
Use examples to get the exact style and structure you want

Microsoft 365 Copilot and Copilot Studio Agents

Use Microsoft 365 Copilot well and build your first agent: what Copilot, Copilot Chat and Copilot Studio each are, how grounding works, Copilot in Word, Excel, Outlook and PowerPoint, prompting and saved prompts, the Researcher and Analyst agents, building and grounding an agent in Copilot Studio, and responsible use.

Tell apart Copilot Chat, Microsoft 365 Copilot, agents and Copilot Studio
Explain grounding and why permissions shape every Copilot answer
Use Copilot in Word, Excel, Outlook and PowerPoint, and check its output

Excel with Copilot and AI for Finance and FP&A

Put AI to work in Excel for finance: Copilot in Excel and its agent mode, what the retired =COPILOT function taught, cleaning data with Power Query, Python in Excel, testing Copilot against Claude and ChatGPT on the same spreadsheet, and building forecasts, dashboards and board commentary without losing control of the numbers.

Use Copilot in Excel on a clean table and check every formula it writes
Classify and summarise text with Copilot, and know why to keep AI away from reported figures
Clean messy exports with Power Query so next month is one refresh

Generative AI and LLM Foundations

What a language model is actually doing when it answers, why it is confidently wrong sometimes, how to call one from Python on a free route, how to run one privately on your own laptop, and how to test one before you trust it with a datasheet. The concept course under the whole AI track.

Explain in plain words what an LLM does when it answers, and why it hallucinates
Choose a model for a job: context length, JSON output, local or hosted, licence
Write a prompt with role, task, context, format and a NOT FOUND rule

Prompt Engineering for Engineers

A course for engineers on writing AI prompts with checkable output and testing them on a golden set. Free to learn; the certificate is optional and paid.

Write a five-part prompt with a refusal rule that turns invention into a visible blank
Fix output format with few-shot examples and get JSON with a schema at temperature 0
Make calculations checkable with chain of thought, and run the arithmetic as code

AI Agents and Workflow Automation with n8n

No-code automation with a language model in the loop, for the jobs an engineering office does by hand: triage maintenance tickets, send the 07:00 plant report, log a phone form into a register, watch a mailbox. n8n runs free on a laptop; the AI node points at a free model or a local Ollama. Every write goes through a human approval step.

Run n8n free on your own laptop and build a form-to-sheet-to-alert workflow
Read and shape data with expressions, Set, Split Out, Aggregate and Merge
Make a workflow safe to run unattended: retries, error workflow, idempotent writes

AI Agents and MCP for Engineers

Build AI agents that read plant data safely: the agent loop, tool calling from Python, the Model Context Protocol, FastMCP servers for a SQL historian, OPC UA and Modbus that are read only by design, hosts from Claude to a local Ollama model, the OpenAI Agents SDK, LangGraph and Microsoft Agent Framework, a maintenance triage agent with human approval, guardrails, evaluation and deployment across network zones.

Explain the agent loop and choose between a workflow and an agent
Write tool definitions and a tool-calling loop in Python, including against a local model in Ollama
Describe MCP hosts, clients, servers, tools, resources and prompts as of the 2026-07-28 specification

RAG and Chatbots with LangChain

A chatbot that answers from PLC and drive manuals, cites the page, refuses what it cannot find, and is measured on a test set. Loading and chunking, embeddings and hybrid search, the RAG chain, query translation, routing, re-ranking, evaluation, LangGraph agents and serving, using free tools and the free tier of a hosted model (daily limits apply).

Load, clean and chunk vendor manuals so parameter tables survive
Embed locally, search with hybrid BM25 + vector retrieval and re-rank with a cross-encoder
Build a RAG chain that cites (doc p.N), refuses with NOT FOUND and handles follow-ups

Private AI with Local LLMs: Ollama, Open WebUI and Offline RAG

Run AI on your own hardware so confidential drawings, specifications and plant data never leave the building: open-weight models and their licences, GPU and RAM sizing, quantisation, Ollama, Open WebUI for a team, the API and Python, offline RAG with citations, datasheet extraction, vision models, benchmarking, air-gapped deployment and an acceptable use policy.

Decide which documents may go to a hosted AI tool, which must stay on a local model and which go nowhere
Compare open-weight models and their licences: Apache 2.0, MIT and the Llama community licence
Size GPU memory and speed for a model from its parameters, quantisation, context length and users

Why learn Generative AI and ChatGPT in India

Large language models have moved from novelty to standard workplace software. Across these courses the core skills are the same: write clear instructions, check the output, protect data, and know when to automate a task with an agent or ground answers in your own documents.

How to choose

If you have never used an AI assistant at work, start with AI Essentials for Work, then Microsoft 365 Copilot and Agents if your organisation runs on Microsoft 365.

Engineers and developers should take Generative AI and LLM Foundations, then Prompt Engineering, then build with n8n agents or LangChain retrieval. Those three are technical; the first two are not.
