What does vibe coding an AI tool mean?

Building a small app around an AI model by describing it to an AI coding tool, then reviewing and steering what it builds. You decide what the tool does and how it behaves; the AI writes most of the code.

Do I need to know how to code or train a model?

No. Most of these ideas call an existing model through an API, so there is nothing to train. It helps to be comfortable testing the results and refining the instructions.

What should I build first?

Something you already ask a chatbot to do again and again: rewriting a message, summarising notes, or making a quiz. One job and one button make the best first build.

How much does it cost to run?

It depends on the model you pick and how much you use it. A personal tool used lightly often costs little, but check the current pricing for your model and set a spending limit before you share it.

How do I stop it making things up?

You cannot rule it out completely, so design for it. Give the model the source text, ask it to say when it does not know, show quotes or links people can check, and test on examples where you know the answer.

Where do the tools run?

Usually as a small web app on Vercel or Netlify, with Supabase for data. Each example lists a stack, and its build prompt explains the setup.

Yes. A free account gets 4 generations a month, 4 ideas each, and you can save ideas and export their prompts.

Can I build one of these examples?

Yes. Every example is free to use. Open one, copy its build prompt into your AI coding tool, or generate ideas shaped around your own work.

Why build your own

Your AI tools, built by you

A focused AI tool can beat a blank chat box. With an AI coding tool, wrapping a model around one job you repeat is within reach of a weekend, with your own instructions built in.

Stop retyping the same instructions.

If you paste the same long prompt into a chat every day, it is ready to become an app. Save the instructions once and give yourself one button.

Show the sources, keep the control.

Your own tool can quote where an answer came from, ask before it acts, and draft instead of sending. You decide how much it does on its own.

Learn how AI apps really work.

Building a small tool teaches you about prompts, costs, and failures faster than reading about them, and you end up with something useful.

Got a prompt you keep pasting into a chat?

Turn it into your own app. Answer a few quick questions and get one prompt that plans the whole build around your setup: the scope, the screens, the data, every step. Ready to paste into your tools.

Tips for your first AI tool

Start with a prompt you already use often. It already does most of the work of the first version.
Test it on a handful of real examples and save them, so you can tell whether a change makes it better or worse.
Show sources or the original text wherever you can, so people can check the answer.
Keep a person in charge of anything that sends, deletes, or spends money. Let the AI draft and let a person approve.
Set usage limits early. Keep your API key on the server and watch your costs from the first day.
