AI processing in Booth Junkie is configured entirely within individual workflow steps, rather than through a single account-wide switch – there’s no separate “turn AI on” step to complete first.
Where to set it up
Open a Photo step – AI processing is a File option on Photo-kind steps only, not Print or Draw – in Admin Panel -> Workflows, and configure your AI prompt directly on that step. Each step’s AI settings are independent, so different steps – or different workflows – can use entirely different prompts.
Once you’ve got a prompt you’re happy with, you can save it for reuse – see Saving AI Prompts as Presets for how that works.

What it costs
See How the AI Credit System Works for what each AI model costs to run, and how credits are charged.
