NewNew course: Vibe Coding, from idea to a working web app

Learn AI engineering by doing it.

Short, practical lessons on how real AI products are built: models, prompting, document search (RAG), agents, evals and shipping. You write real Python in your browser, and you can't move on until you get it.

Pick a path, or start with both.

How it works

No 3-hour videos. Just practice.

Each lesson takes 5–10 minutes. Every step asks you to try something, and you get instant feedback.

01

Read one idea

One idea, explained simply, with an animation that shows how data moves through the system.

02

Do it yourself

Write Python, put steps in order, play with live widgets, sort and match. You have to get it right to continue.

03

Get instant feedback

Hints when you're stuck, explanations when you're right, plus XP and levels to keep you going.

Every lesson ends in something real, like this RAG pipeline:

Your question
Turn into numbers
Search
Reorder results
Prepare the prompt
LLM
Answer with sources

Know the difference

AI engineer ≠ ML engineer ≠ software engineer.

They overlap, but the daily work is very different. The AI Engineering course trains AI engineers, and teaches enough ML to work well with ML engineers.

Software Engineer

Builds reliable systems with deterministic code.

  • APIs, databases, infrastructure
  • Testing & CI/CD
  • Output: apps & services

ML Engineer

Trains, tunes and serves models from data.

  • Data pipelines & features
  • Training, tuning, MLOps
  • Output: trained models
This course

AI Engineer

Builds products on top of foundation models.

  • Prompts, context & RAG
  • Tools, agents & evals
  • Output: LLM-powered features

Questions? Answers.

What is keepUp AI? +

keepUp AI is an interactive learning platform with two courses. AI Engineering teaches you to build real AI products with real Python in your browser, labs, quizzes and case studies. Vibe Coding teaches beginners to build, review, debug and launch a real web app with AI coding tools.

Is it good for beginners? +

Yes. Vibe Coding needs no programming background. For AI Engineering, if you can read basic Python you can start today: every AI idea, from tokens to agents, is taught from zero with plenty of practice.

What's the Vibe Coding course? +

A beginner course where you plan, build and launch TinyTasks, a responsive web app with Clerk sign-in, a Supabase database with access rules, PostHog analytics and a test-mode payment exercise. It's included in every plan, and the first module is free.

Can I try it for free? +

Yes. The first module of each course is completely free (in AI Engineering that's the first 5 lessons), including Keepy the AI tutor, with no card and no sign-up. You can also unlock bonus lessons by inviting friends.

What will I be able to build? +

In AI Engineering: LLM features with validated outputs, RAG assistants over your own documents, tool-using agents, MCP servers and eval suites, plus 36 copy-paste templates. In Vibe Coding: a launched first version of your own web app with sign-in, a secure database, analytics and a README.

How is this different from video courses? +

You can't move on until you've actually done the thing. Every step asks you to write code, review a change, sort, match, solve a quiz or analyze a real case, so the skills stick.
