Why You Need This Checklist

What if the reason your AI-generated slides look generic has nothing to do with your prompts, and everything to do with what you do before you prompt? That one shift is what separates polished, professional decks from the bland, forgettable ones most people end up with.

Here is the frustrating reality most beginners face: you open Claude Design, pick a template, start typing, and fifteen minutes later you have something that looks like it came from a 2009 PowerPoint tutorial. You spend more time trying to fix it than it would have taken to build it manually. The tokens pile up, the slides stay mediocre, and you wonder if AI design tools are actually worth the hype.

They are worth it. You are just starting in the wrong place.

Jeff Su, a productivity creator who has used Claude Design to build decks for real paid workshops, discovered that the entire outcome depends on three files you prepare before you ever open the tool. When those files are in place, your first draft already looks good. Every round of feedback makes the next deck better automatically. Your logo, your colors, your voice, your layout preferences — all of it carries forward without you repeating yourself.

In his video, Jeff walks through exactly how he built a design system from a publicly available GitHub resource, cleaned it with a simple ChatGPT prompt, uploaded it to Claude Design, and turned it into a reusable presentation template that gets smarter every time he uses it. He used the same workflow to create carousel slides for social media and branded visuals for his newsletter campaigns.

This checklist captures every step of that process so you can follow along without rewinding the video fourteen times. It covers how to find and clean a design.md file, how to build and customize a design system inside Claude Design, how to generate and refine a slide template, how to use the edit, annotate, and tweaks features for surgical changes, and how to export your finished deck in a format that works everywhere.

If you are done wasting time on presentations that do not look the way you want them to, this checklist is your starting point. Work through it once, set up your system, and every deck you build after that gets easier and better.

Every checklist item comes with actionable notes to guide you — things like "Don't forget to do this before you start," "Avoid this common mistake," or "Set a reminder for 30 days out." Nothing vague, just clear next steps.

DOWNLOAD Find a design.md file from a real brand using the public GitHub repository Jeff references

DO Open ChatGPT (or any AI chatbot) and upload the downloaded design.md file

DO Rename the cleaned output file to something descriptive, such as 'subtle gradient design system'
