# Introduction

> Track brand visibility across the AI platforms customers actually use.

OpenLens measures what AI systems say about your brand. We cover seven of them: ChatGPT, Perplexity, Google AI, Gemini, Grok, Claude, and DeepSeek. Run prompts across all of them, see who gets mentioned, where the answer is sourced from, and how the picture shifts over time.

OpenLens comes in four tiers: Free, Starter, Agency, and Enterprise. [Plans and pricing](/pricing/plans) covers what each one includes. For enterprise needs, email [contact@aibread.com](mailto:contact@aibread.com).
