Bottom line: Code.org, now branded CodeAI, offers one of the clearest free starting points in AI: its AI Foundations curriculum is 100% free, needs no prior experience, and takes learners from how AI works to building web apps with AI as a partner. It is designed for grades 9–12 classrooms, so adult self-learners get excellent free material but no formal certificate or job credential.
What is Code.org (CodeAI) AI Foundations?
Code.org is a nonprofit education organisation, rebranded as CodeAI, dedicated to giving every student a chance to learn computer science and AI. AI Foundations is its complete high school AI and computer science curriculum, available in full-year, semester, or individual-unit formats.
Semester one, Exploring AI and CS, covers AI literacy, how computers and the internet work, cybersecurity, and data. Semester two, Designing and Building with AI, teaches JavaScript while students build interactive web apps using AI as a creative partner. Every unit integrates ethics, bias, and responsible AI practice, and the curriculum is aligned to CSTA 2026 standards and the TeachAI AI Literacy Framework.

What is good about it?
- Completely free, with no catch listed: the official page states the curriculum is 100% free, including detailed lesson plans and an AI Teaching Assistant.
- Truly beginner-friendly: no prior experience is required for students or teachers, and it runs on a Chromebook or computer.
- Ethics is built in, not bolted on: bias, hallucinations, privacy, and responsible use appear in every unit.
- Hands-on tools: learners experiment in AI Chat Lab, write real Python in Python Lab, and build web apps in Web Lab instead of only watching videos.
- Flexible formats: a full year (90 class periods per semester), one semester, or single units such as Problem Solving with AI and Foundations of AI Programming.
What is not so good?
- Made for classrooms: pacing, lesson plans, and assessments assume a teacher and a class. Solo adult learners have to self-direct.
- No job credential: there is no listed certificate to put on a resume or LinkedIn, unlike paid professional programs.
- High-school level: experienced programmers will find the early material too basic; they would move faster with a guide like our How to Use ChatGPT beginner’s guide plus a coding course.
- English only: the official page lists English as the supported language for AI Foundations.
