the short answers. no fluff.

is promptdojo free?
the web preview is free forever. three chapters, runs in your browser via pyodide, no signup. the full 26-chapter school ships in the native app at $9.99/mo, $59/yr, or $129 founders lifetime.
do i need to sign up to use the free preview?
no. the web preview requires no account. open the page, run the code. signup is only needed if you want progress to sync across devices, which is a pro feature.
do i need to install python?
no. every lesson runs in your browser via pyodide. no python install, no virtualenv, no anaconda. mobile and desktop both work.
is there a paid tier?
yes — the native app. $9.99/mo, $59/yr (41% off monthly), or $129 founders lifetime (first 100 only). the web preview remains free forever for the first three chapters.
what do i get for $129 founders?
lifetime access to every chapter promptdojo ever ships, in the native app. no renewal. first 100 reservations only, then the price moves to $199.
who is this for?
people who use cursor, claude code, copilot, or windsurf every day and need to read what the ai writes, catch the bugs ai introduces, and direct the ai deliberately. pms, marketers, ops folks, and beginners who already build with ai assistance.
when does the native app ship?
when the waitlist clears 1,000. join the waitlist on this page for the launch ping and a founders code.
