axd.ax is an open reference site for Agent Experience design. It documents the principles, dimensions, patterns, and scoring system practitioners use to evaluate and improve how AI agents interact with digital products.

The content is maintained by the team at Optagen.ai, a company focused on Agent Perception Optimization: helping brands understand and improve how AI agents find, describe, and recommend their products.

AX is a young discipline. The principles here are grounded in current practice across the major AI platforms: ChatGPT, Claude, Perplexity, and Gemini. They will evolve as agents become more capable and more deeply embedded in how work gets done.

If you want to know how AI agents experience your product today, start with the AX Score. If you want a professional audit and a roadmap for improving your position, visit optagen.ai.
