This is a McKinsey-style PowerPoint generator that uses a five-stage workflow to prevent the sloppy outputs that plague most AI presentation tools. It enforces hard gates at each step using actual Python scripts that check for things like text overflow, inconsistent fonts, and malformed API calls. The engine wraps python-pptx with 67 high-level methods across categories like frameworks, timelines, and dashboards, all designed to match consultant-grade slide decks. What's interesting is the self-refinement system that makes the AI write down pattern-level mistakes into experience files so it stops repeating them. It even generates cover images via Tencent Hunyuan with that signature McKinsey ribbon decoration. You'll want this if you're building pitch decks, board slides, or quarterly reviews and actually care about production quality instead of just getting something that technically opens in PowerPoint.
