AI-generated UI is inaccessible by default

Claude Code, Cursor, and ChatGPT generate semantically inaccessible UIs because LLMs optimize for visual appearance—Vercel's v0 demonstrates that hardcoding accessible component primitives into generation pipelines solves the gap.

AI code generation tools like Claude Code, Cursor, and ChatGPT produce visually correct but semantically inaccessible UI by default. The article explains why LLMs optimize for visual output while generating near-zero semantic information for the accessibility tree, then proposes a five-layer enforcement system combining prompt constraints, static analysis, runtime testing, CI integration, and accessible component abstractions. Tools like Vercel's v0 demonstrate the effectiveness of hardcoding accessible primitives into generation pipelines.
