I offer you mentorship on how to be a data activist by using AI for social impact.

About me: Dr. Celestine Preetham is founder of Caring Machines, on a mission towards sustainable artificial intelligence. He was born (1992) in Chennai, schooled in SBOA Anna Nagar and St. John's Besant Nagar, and self-studied to secure an All India Rank of 45 in JEE-2009 (with AIR 6 in the mathematics section). Given his love for applied physics, he pursued his B.Tech in Electrical Engineering from IIT Madras and landed a final year internship at the MESA+ institute of Nanotechnology, University of Twente, the Netherlands. He was employed to continue his research there from 2013-2018 and was awarded a PhD for his thesis on "Evolving Networks to Have Intelligence Realized at Nanoscale". He has been a visiting scientist at the Institute of Mathematical Sciences, Chennai in 2019 and a postdoctoral scientist in the Bernoulli Institute for Artificial Intelligence, University of Groningen, the Netherlands from 2020-2024.

While adults are still debating whether kids should use AI, they are already using it.
The question isn't "should they?" it's "how do we do it intelligently?"

In this course, your child will discover:
✓ What AI actually is: not magic, not mystery. How machines think, what they can do, what they can't
✓ How ChatGPT really works: not just "ask a question and get an answer," but why it responds that way, where it fails, when to trust it
✓ What LLMs are (Large Language Models): in language they understand, not tech jargon
✓ Create with AI: custom avatars, interactive stories, real projects using real tools
✓ Think critically about AI: Bias, privacy, creativity. What does AI do better than humans? What can't it do?
✓ Real-world applications: How AI transforms medicine, education, art, gaming, everyday life

Why this is different:
Most AI courses for kids teach "here's the tool, use it." I teach how to think about AI.
Your child will learn to see AI not as black magic or a solution to everything, but as a powerful tool with real limits.
And, more importantly: that they can control how they use it.

What they take home:
Real projects they created (custom avatar, interactive app, analysis of a real AI case study). A genuine understanding of how it works. And the ability to use AI responsibly and creatively.

Format: Online | 60–90 min sessions | Flexible, adapted to their age and pace

For curious kids asking "How does ChatGPT actually know things?"

A (60-minute) tour for children and teenagers who already use technology, ChatGPT, images, games, and for families who want that curiosity to have method, limits, and a visible result.

No prior assessment is necessary. The first class serves to get to know the student, adapt the pace (also if there are special educational needs) and choose the type of project.

What we do in weeks

Weeks 1–2. How an AI “learns”
With short projects, we observe data, patterns, and biases. The goal is not to memorize definitions, but for students to be able to explain, in their own words, why a tool is right or wrong.

Weeks 3–4. Create with discernment
Art, stories, or game ideas using generative tools. We work on prompts, what can be published, privacy, copyright, and when not to use AI (for example, to copy homework).

Week 5. Final Project
A mini-project of their own: a co-written story, a series of images, a simple classifier, a game idea... Something they can show at home and explain how they did it.

What does the family take with them?
• a 5-week overarching theme, not random, aimless classes
• Safe usage habits that are also useful at school
• Finally, a completed project and a brief note on how to proceed.

If the student has SEN (ADHD, dyslexia, organizational or rhythm difficulties), I break the work down into shorter steps, use visual aids, and measure progress in specific tasks, not speed.

AI is everywhere, but knowing that does not make it easy to begin. Many people feel overwhelmed, uncertain, resistant, or worried that they are already behind.

These lessons are designed for complete beginners who want a calm and supportive way to enter the world of AI.

I will help you understand how to approach AI, what it can realistically do for you, and how to begin using it without feeling intimidated. We will work at your pace, using real examples from your work, daily life, interests, or personal goals.

The focus is not only on learning the technology. It is also about building confidence, reducing hesitation, and helping you feel comfortable experimenting independently.

Depending on your needs, we can explore:

how to start a conversation with an AI tool
how to turn unclear thoughts into useful requests
how to recognize where AI can genuinely help
how to improve disappointing or inaccurate answers
how to verify information and avoid common mistakes
how to use AI safely without sharing sensitive information
how to choose between different AI tools without becoming overwhelmed
how to develop your own comfortable and practical way of using AI

No technical knowledge or programming experience is required. The goal is for you to leave the lesson feeling more confident, curious, and capable of continuing on your own.

Hello,

After a 34-year career in systems engineering (including roles as AVP System Engineer & Product Owner at Moody's), I've learned one essential truth: technology is useless if it remains overly complex.

There is NO set curriculum or pre-defined syllabus: every session is 100% tailor-made. I adapt entirely to your request, your skill level, and your current objectives—whether that means gently discovering a new tool or solving a specific technical challenge.

My approach is built on clear, accessible guidance: no unnecessary jargon, no dull theory, and no prerequisites required. My goal is to make technology accessible, seamless, and immediately useful (if my experience helps you avoid a few costly surprises, then I’ve done my job).

Examples of what we can cover together:

Discover and Master AI (ChatGPT, Copilot, Claude, Gemini, Veo, etc.)

Learn how to write clear prompts to get accurate results (prompt engineering).

Use AI to draft content, summarize documents, analyze data, or organize your daily work.

Understand best practices to use these tools securely.

Simplify and Automate Your Daily Tasks

Connect your collaborative tools (emails, files, calendars, M365 services) to eliminate repetitive actions.

Migrate to new M365 services smoothly.

Set up simple virtual assistants to save you time.

Optimize Your Digital Tools & Cloud Environment

Take control of your IT workspace, organize collaborative environments, and secure your access.

How?
We start with YOUR topics: a practical problem to solve, a project to bring to life, or a tool you want to master. Everything is explained clearly and patiently so that you leave every session with practical, actionable solutions.

Whatever your starting point or project, the course adapts to you—never the other way around.
