jwynia built this as a diagnostic framework that pushes back against bullet point hell and the data dump. It walks you through audience planning, assertion-evidence structure (state your point as a sentence, back it with visuals), and cognitive load management. The evaluation tables are genuinely useful for catching when you're designing for yourself instead of your audience. Works across any tool since it's about principles, not PowerPoint features. The anti-patterns section nails common mistakes like putting your entire script on slides or drowning people in uninterpreted charts. If you've ever sat through a presentation that was just paragraphs read aloud, this gives you the structure to do better.
