Improving visual polish using independent AI critic subagents
Coding models struggle to evaluate their own user interface choices because they are biased by their existing code and context. Setting up a second, higher-capacity AI agent to evaluate design screenshots creates an objective feedback loop that pushes visual quality higher.
Try it yourself
- 1Take a screenshot of the current user interface rendered in the browser.
- 2Pass the image to an independent critic agent in a fresh chat context without including source code.
- 3Direct the critic model to evaluate aesthetic quality, flag common AI design cliches, and provide a numerical score.
- 4Have the coding agent implement requested fixes repeatedly until the critic assigns a passing grade.
Copy this prompt
Refine this user interface design by using a separate critic model. At each step, capture a screenshot of the layout, send only the image to the critic agent in a fresh context, ask it to evaluate visual quality against a professional design studio bar, and implement changes until it gives a score of 9 out of 10 or higher.
The Blend
Former Apple design leader Anshu Chimala detailed a method for overcoming the generic visual outputs produced by software-building artificial intelligence. In a newsletter post hosted by Lenny Rachitsky, Chimala pointed out that code-generating models frequently struggle with interface design because they default to conservative, predictable choices. To fix this, creators can deploy a separate reviewer agent that inspects actual screenshots of the output, offering impartial feedback without being influenced by the underlying code.
This approach matters because software tools powered by artificial intelligence are quickly becoming the primary way non-technical creators build web pages and mobile applications. Standard prompts usually yield repetitive, uninspired layouts with basic styling. By splitting the building and critiquing roles between distinct digital agents, software creators can automatically refine visual quality and achieve high-end results far faster than manual editing previously allowed.
It remains uncertain how smoothly these automated critique loops can scale for complex, multi-page software without significantly raising computing costs. Beyond efficiency, an open question is whether using automated critics will inspire genuinely original aesthetics, or simply standardize software around a new, slightly sleeker set of machine-approved design rules.
