Questions before you start

Are these AI tutorials free?

Yes. Every 101 course on OverpayingForAI is free, has no sign-up, and works on any device. Progress is saved in your browser.

Which AI should a beginner learn first?

Start with the one you already have access to. ChatGPT, Claude and Gemini all have free tiers that cover the basics in these courses. The pricing lessons in each course show when paying is actually worth it.

Do the prices in the tutorials stay current?

The price figures are drawn from the same catalogue that powers the site's pricing tracker, so they redraw whenever the catalogue updates. Prose figures are marked as 'at the time of writing'.

How long does each course take?

About an hour of reading per course, split into eight lessons of six to twelve minutes. Each lesson stands alone, so you can jump straight to pricing, prompting or the API quickstart.

If our calculators helped you cut down on hidden AI wallet leaks, consider buying us a coffee. A tiny fraction of your savings keeps our pricing indexes updated daily.
