Short cards in plain English. Never a wall of text.
Answer a quick quiz
Check you really got it before you move on.
Run real code
Edit and run HTML, CSS, JavaScript, TypeScript, SQL and Python in your browser. Nothing to install.
Build a streak
Earn XP and keep a daily habit going.

What is learn@aiera?
learn@aiera is a free learning website that teaches coding, AI, data, design, money skills and more from zero, in plain English. It has 111 courses and 471 short lessons across 15 categories, with quizzes, code you can run in your browser, and an AI learning companion called Aira.
Is learn@aiera really free?
Yes. Every course and lesson is free, and you do not need an account to learn. A free account is only needed to take the final assessment and get a certificate, and to keep your progress across devices.
Do I need any experience to start?
No. Every topic starts from zero and has three levels: beginner, intermediate and advanced. You can begin with the beginner course and move up when you are ready.
What is the ZERO method?
The ZERO method is how every lesson is written: Zero assumptions (we never assume you already know something), Explain simply (plain English and everyday analogies), Reinforce (quizzes make the ideas stick) and Operate in practice (you try it yourself straight away).
What is Aira?
Aira is learn@aiera's AI learning companion. You can ask her a question about a lesson and she answers in simple English with a small example. She can be wrong, so check important facts in the lesson or in official documentation.
How do I get a certificate?
Finish every lesson in a course, sign in with a free account, then pass the final assessment: 15 questions picked at random from the course, with 80% or more needed. If you do not pass you can try again after 7 days. The certificate is free, can be downloaded as a PDF and has its own shareable link. It is a certificate of completion, not an accredited qualification.
