About

Lettertrace is an open source AI visibility monitoring platform that measures how often Claude, ChatGPT, Gemini, and Google AI Overviews mention and recommend a brand. Users add the topics their buyers ask about, and the platform automatically generates natural prompt variations to monitor how AI assistants actually answer those questions. Every run becomes a datapoint, allowing teams to track visibility, prominence, sentiment, and share of voice per topic and model over time. Competitor benchmarking shows how often rival brands appear, which companies AI models recommend, and how a brand performs against each competitor. Reports turn raw AI answers into the metrics AEO and GEO teams need, including brand visibility, share of voice, sentiment, recommendations, and competitive performance. Scheduled monitoring can run daily or weekly to build actionable trend lines, while multi-model analysis makes it possible to compare results across answer engines side by side.
