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.

Share and access study materials worldwide — with AI study tools built in
Search a vast, student-contributed library of lecture notes, summaries, study guides and past exams organised by course and institution.
Generate notes, summaries and revision material from documents so you can study the essentials instead of re-reading everything.
Turn study material into interactive quizzes and flashcards so you can test yourself and target weak spots.
Use built-in text-to-speech to listen to study documents on the go, useful for revision during commutes or downtime.
