Credits are consumed by different features: generating an article uses 1 credit, running a content analysis uses 2 credits, AI image generation uses 1 credit per image, bypassing AI detectors (AI rewriter) uses 2 extra credits (3 total with the article), and AI chat or AI auto-fix each use 0.5 credits. Free tools (SEO Checker, Keyword Analyzer, etc.) don’t cost credits. Credits reset at the start of each billing cycle.
