A free, no-signup resource that teaches AI to developers — from zero-to-builder basics to AI/ML interview and cloud-certification prep — built and maintained by Yunus Shaikh.
Most AI explainers are either hand-wavy or drowning in math. AI Mastery is the in-between: plain-English answers and animated, interactive explainers (see the visual courses on RAG and generative AI) that build real intuition, plus a deep interview/cert question bank for people going further. It's free, ad-free, and runs entirely in your browser.
I'm Yunus Shaikh, a fullstack developer who builds with LLMs day to day. I created this site to be the resource I wished I'd had when I started with AI — and to keep my own understanding sharp by explaining things simply. You can find me on LinkedIn and GitHub.
Questions and explanations are drafted with AI assistance and then fact-checked in a separate pass — dates, model names, cert codes, and formulas are verified against primary sources (for example, the visual RAG course cites the 2020 Lewis et al. paper and the generative-AI course cites the 2021 CLIP paper). Time-sensitive facts are framed as "as of 2026." If you spot an error, please reach out on GitHub.
The builder track teaches AI from scratch; the advanced track covers 445 interview + AWS/Azure/GCP certification questions; the visual courses explain RAG and generative AI with animation; and there are static, searchable guides under /guides/ and /topics/.
