Free online education in AI, engineering and life skills — given by volunteers, for people who never had the chance to learn.
“And they that be wise shall shine as the brightness of the firmament; and they that turn many to righteousness as the stars for ever and ever.”
DANIEL 12:3Distance, money, disability or circumstance keep many people out of the classroom. Haewol brings the classroom to them — free online courses, built and taught by volunteers who give their skills as a gift.
Practical online courses in AI, engineering and everyday skills — free, open to all, forever.

We turn it into a short, subtitled online course
Learners study free, on any phone, anywhere
Graduates return as mentors and teachers
Short video lessons with hands-on practice, chosen for one goal: skills that lead to study, work and a better life. No fees, no entry exams.
What AI is, how to use it safely, and how it can change your work.
Write, research, translate and study faster with AI as your tutor.
Turn repetitive tasks into small programs — your first real tool.
Read tables and charts, find the source, tell what the numbers really say.
The algebra, geometry and physics every engineer uses daily.
Forces, gears, shafts and mechanisms — with simple home experiments.
Read technical drawings and model your first part in free CAD software.
Voltage, current and sensors — build circuits on a simulator.
Computer, internet, email and online safety from the very first step.
Enough English to follow global courses and write a job application.
Logic and creativity through games and visual programming.
Plan a path, build a portfolio, prepare for interviews with a mentor.
Courses open one by one as volunteers record them. Every course is free, and stays free.
The moon gives light to those who walk at night. Our courses are made first for people learning in hard places — and designed so that nothing but a phone is needed.
Villages and small towns without teachers in AI, engineering or technology.
Starting with our partner school in Mongolia, then wherever we are invited.
People who had to stop studying for work, family or hardship.
Low income, disability or circumstances that keep the classroom out of reach.
Good education should not need a fast connection or a new laptop.
No fees, no subscriptions, no hidden costs.
Every lesson works on an ordinary smartphone.
Short videos, compressed files, downloadable lessons.
Subtitles in English, Korean and Mongolian, with more to come.
Haewol runs on 재능기부 — the gift of talent. One hour of your knowledge, recorded once, can teach thousands of people you will never meet.
Record a short course on what you know best — engineering, AI, a language, a craft.
2–4 hours a monthMeet learners online, answer questions, review their projects, encourage them.
1 hour a monthCheck AI-made subtitles so every lesson reaches learners in their own language.
FlexibleDevelop the platform, the AI tutor and the tools that make volunteers more effective.
Project-basedTurn raw lectures into clear slides, diagrams and short, well-paced videos.
FlexibleYou bring the knowledge. We help with everything else.
Sign up as a volunteer and tell us what you would like to give and how much time you have. A short online call helps us match you with the right role and learners.
Shape your topic into short lessons of five to ten minutes, each with one clear outcome and a small practice task.
Record at home with a phone or laptop. Our editors and AI tools clean the audio, add subtitles and prepare translations.
Your course goes live for free. Join monthly live Q&A if you can, and see how many learners your lessons reached.
Every decision starts with the person who has the least access.
No contribution is too small. One lesson can change a life.
Everything we make is free — for learners and for the world.
A volunteer can teach a lesson once. With AI, that lesson can answer questions at midnight, speak another language and adapt to each learner. People teach; AI carries the light further.
A patient teacher for every learner, at any hour
One recording, many languages
Less preparation time for volunteers
Human first: every AI-made lesson, subtitle and answer is guided and reviewed by volunteers.
“And God made two great lights; the greater light to rule the day, and the lesser light to rule the night: he made the stars also.”
GENESIS 1:16
A crescent moon and the evening star over the last light of the day. The light we receive, and the light we pass on — we hope every volunteer and every learner becomes one of those stars.
