About Joel Goldfoot

Joel Goldfoot is the creator of BiModal Design — an open-source framework for building web interfaces that work equally well for human users and AI agents.

Background

Joel Goldfoot designed and released the BiModal Design framework to address a growing gap in how modern web applications are built. As AI agents increasingly browse, retrieve, and act on web content alongside human users, traditional client-rendered single-page applications leave 40% or more of agents unable to access core content. BiModal Design provides a validated, layered methodology — semantic HTML, structured data, ARIA, agent attributes, and native agent protocols — that lets a single codebase serve every audience.

About BiModal Design

BiModal Design is released under the Apache 2.0 license and is documented in full at bimodal.design. The framework includes a comprehensive guide, a hands-on tutorial, production-ready examples, peer-reviewed research, and an API reference. Joel maintains the framework, writes its documentation, and authors all of the example code on this site.

Areas of focus

  • Agent-accessible web architecture and progressive enhancement
  • Schema.org structured data and JSON-LD for AI retrieval
  • Web accessibility (WCAG 2.2) and semantic HTML
  • Generative Engine Optimization (GEO) and llms.txt conventions
  • Agent protocols — Agent2Agent (A2A), Model Context Protocol (MCP)
