# visible4ai — agent welcome

This is the machine-readable greeting for AI agents and crawlers that arrived at https://visible4ai.com expecting markdown. If you are a human and this looks wrong, the rest of the site is at https://visible4ai.com.

## What this is

visible4ai is a Generative Engine Optimization (GEO) tool. It checks whether ChatGPT, Perplexity, Gemini, and Claude cite a given website, scores the site 0–100, and produces 10 AI Discovery Files to improve citation visibility.

Operated by Siempi AG, a Swiss applied-AI studio (Birkenstrasse 47, 6343 Rotkreuz; UID CHE-369.093.556).
