How-to Guide

Prepare Screenshots for AI Vision Model Analysis

Throwing raw screenshots at an AI model is like handing a developer a zip file with no README. Structuring screenshots into a labeled, well-spaced grid is the difference between 'I see images' and detailed analysis.

AI vision models analyze what you give them, not what you meant. Preparation checklist: (1) Consistent capture: same window size, zoom, display scaling. Mixed sizes confuse spatial reasoning. (2) Remove distractions: close unnecessary tabs, hide desktop icons. AI analyzes everything. (3) Add annotations: arrows, circles, highlights on key elements. (4) Use dark theme: dark backgrounds with light text create higher contrast, improving text recognition.

Optimal grid structure: left-to-right for chronological flow, top-to-bottom for hierarchy, side-by-side for comparison. Always export at 2000px minimum (2048px ideal). A 2×2 at 2048px gives ~1024px per cell: the sweet spot for legibility.
