A free 14-day AI course built for total beginners
Fourteen bite-sized lessons, each focused on one useful thing you can do with AI rather than theory or jargon.
Written for people with zero AI background, so you never hit a wall of unexplained terminology.
Lessons touch prompting, AI writing, translating, image generation, summarising and light coding help.
Each day has a mark-as-complete toggle so you can see your progress and pick up where you left off.

Learn just enough code to launch a real online business in 14 days
Fundamentals, a full SaaS build, and the business side — payments, domains, hosting, SEO — are covered in about twelve hours of video instead of the dozens of hours a conventional JavaScript course spends on topics you will never use.
Rather than theory for interviews, you progressively build a real authenticated, paying SaaS, which is the actual deliverable of the course.
Sections on AI-powered coding and design show how to use AI to explain code, fix bugs and generate parts of your app, framed as leverage on top of fundamentals.
The syllabus includes the non-coding skills that decide whether an app makes money: copywriting essentials, payments with Stripe and LemonSqueezy, domain and DNS setup, hosting and SEO.
