Welcome to LLM Index Watcher

LLM Index Watcher measures how often the major AI assistants recommend your brand. On a schedule — daily on paid plans, weekly on Free — it asks the assistants it tracks (ChatGPT from OpenAI, Claude from Anthropic, Gemini from Google, Grok from xAI) the questions your buyers ask, records which brands each answer recommends and in what order, and turns that into a 0–100 Visibility Index per assistant, per mode and per language — plus share of voice against your competitors, the sources the assistants cite, alerts when anything moves, and concrete recommendations.

Where to start

• Getting started — from your URL to the first report in minutes.
• Plans — what Free, Starter and Pro include.
• The Visibility Index — exactly how the number is computed.
• Providers, modes and languages — what is measured and with which models.
• Share of voice, Citations, SERP tracking.
• Alerts and the weekly digest, Reports and the instant check.
• FAQ and Privacy.

Principles

1. Official APIs, never scraping. Each provider is queried through its API with the consumer-default model of its assistant.
2. Measure what buyers see. Questions are tracked natively in each language, not translated, and in model-knowledge mode plus, on paid plans, live web-search mode.
3. A number that moves. Position-weighted, averaged across every question, assistant, mode and language, so each check compares with the previous one.
4. From metric to action. Citations and the advisor say what to do, not only where you stand.
