Vibe coding: build a small app with an AI coding tool

What you will be able to do

Skills you add to your Herizon profile when you finish: Web Development Basics, AI-assisted Development.

• A small app of your own, live on a link you can share
• A way to write prompts that get what you meant
• A routine for finding and fixing a bug when something breaks
• Secrets kept out of your code, and access rules you have tested
• A clear sense of when to bring in a developer

Who it is for

Time per page: 15 to 30 minutes Whole course: 4 to 5 hours (12 pages, at your own speed) This is for you if you are: - A coordinator or founder who wants to replace a spreadsheet with a page - A jobseeker who wants a real project to show - An operator or marketer who needs a small internal tool - Changing career and curious about building You need no programming experience. It helps to think clearly about what you want, because the tool builds what you describe. ---

The situation you work through

Eero, a volunteer coordinator at a food bank in Tampere, builds one small shift sign-up page with an AI coding tool: a first prompt, a shared link, a bug fix and a safe way to save sign-ups.

Your practice task

Build one small app of your own with an AI coding tool: a page where visitors do one thing and something is saved. Put it on a live link, test it with three people, find and fix one bug, and check that no secret key sits in your code and that access rules are in place. Submit the live link, your first prompt word for word, and three sentences on what the app does, which bug you fixed, and your next step.
