No. You pay R1 250 once through PayFast and keep the guide for life, including its upgrades.
Is it included in my AussyPrompt ONE plan?
No. Premium Guides are sold separately from every subscription plan, so you only pay for the guides you want. If you're on ONE, your guides open right inside your ONE workspace.
Do I need to know how to code?
Claude Code writes the code from the prompts in the guide. You paste each prompt, check the result and follow the steps, and the guide lists common problems and how to fix them.
What else will I pay for?
