What is Taste Lab?
Taste Lab is a tool that reverse-engineers the design aesthetics of any website, providing a structured output for AI agents. It processes a given URL through a four-step pipeline, involving specialized AI roles to extract precise design measurements, detect systemic patterns, infer design trade-offs (Taste DNA), and ruthlessly filter the analysis.
The output consists of two files: a Markdown file and a JSON file. The JSON file contains a "Design Map" with a complete token set of colors, typography, spacing, radius, and shadows, along with "Taste DNA" which details four core design principles, including the trigger for the decision, the decision itself, the underlying reason, supporting evidence, and the trade-offs made. This structured design context enables AI tools to understand and build upon a website's design choices without manual setup or pasting.

Taste Lab FAQ
How does Taste Lab help AI agents understand website design?
Taste Lab reverse-engineers website design aesthetics, providing AI agents with a structured output that includes a 'Design Map' of tokens like colors and typography, and 'Taste DNA' explaining design principles and trade-offs. This allows AI tools to build upon a website's design choices without manual setup.
What kind of output does Taste Lab generate?
Taste Lab generates two files: a Markdown file and a JSON file. The JSON file contains a 'Design Map' with a complete token set of design elements and 'Taste DNA' which details four core design principles, including the trigger, decision, reason, evidence, and trade-offs.
Which teams would benefit most from using Taste Lab?
Teams working with AI agents, particularly in design and development, would find Taste Lab most beneficial. It automates the complex process of design system analysis for AI, facilitating consistent design application by AI agents.
How does Taste Lab compare to a tool like Avocode?
Taste Lab focuses on reverse-engineering design aesthetics for AI agents, providing structured output and identifying the 'why' behind design choices, including trade-offs. While Avocode might focus on design handoff and collaboration, Taste Lab's primary purpose is to enable AI tools to understand and build upon existing design systems.
What are the main limitations of Taste Lab?
Taste Lab requires some technical setup, including cloning a repository and installing Playwright. It is primarily designed for AI agent consumption rather than direct human UI analysis, and its output might need further processing for specific design tools beyond AI agents.
Does Taste Lab include a free tier?
Taste Lab is free to use, meaning there is no paid plan required to access its functionalities.
Can Taste Lab integrate with existing AI development environments?
Yes, Taste Lab is open-source and designed to integrate with popular AI development environments. This allows developers to seamlessly incorporate its structured design context into their AI tools.
