    StyleSeed
    2026-04-06

    A design engine for AI coding assistants (Claude Code, Cursor, Codex) that teaches design judgment through 74 rules covering color, spacing, hierarchy, elevation, and motion.

    CodeSyncer
    2026

    An AI context recovery tool that helps Claude 'remember' code and session state using semantic code search.

    Market Position

    Differentiates from standard component libraries by focusing on 'design judgment' and constraints for AI agents to prevent generic outputs.
