Claude's vision model excels at reading and reasoning about text in images — making it ideal for code screenshots, documentation, data tables, and labeled interfaces. When you feed it a grid, it doesn't just describe each cell; it reasons across them, comparing implementations, identifying inconsistencies, and synthesizing findings. Optimal Claude grid configurations: (1) code review — 1×3 showing original code, proposed changes, and test output; (2) document analysis — 2×2 showing 4 pages or sections of a contract, policy, or specification; (3) UI audit — 2×3 showing 6 screens of an app for consistency analysis; (4) data comparison — 1×3 showing three dashboard screenshots at different time periods. Claude handles large images well — export at 2048–3000px. Describe the grid structure explicitly in your prompt; Claude follows structured instructions with exceptional precision.

How to Do It — Step by Step

  1. 1
