# PromptRank > PromptRank is a Generative Engine Optimization (GEO) tool that measures how often AI assistants — ChatGPT, Claude, Gemini, Grok, and DeepSeek — recommend a business. Enter a business name, city, and category to get a 0–100 PromptRank score, a competitor map, and a per-model breakdown of where you are mentioned and where you are missing. PromptRank runs 25 buyer-intent prompts (five each across the five models) and records whether a business is named, in what position, and which competitors appear instead. It is to AI search what SEO is to Google: instead of ranking ten blue links, you compete to be named in the AI answer itself. A free audit needs only an email; the Pro and Agency plans unlock the full report and deep audits that run a live web search and capture the exact pages each model cites. ## Product - [Run a free AI visibility audit](https://www.trypromptrank.com/): Enter a business name, city, and category to see how ChatGPT, Claude, Gemini, Grok, and DeepSeek answer, and get a 0–100 PromptRank score in about 60 seconds. - [Pricing](https://www.trypromptrank.com/pricing): Free (2 audits per week, preview report), Pro ($29/mo — 20 deep audits, full report), and Agency ($99/mo — 100 deep audits plus a multi-client workspace). ## Research Proprietary studies of how AI engines pick businesses — original data, reproducible methods. - [How AI recommends local businesses](https://www.trypromptrank.com/research/how-ai-recommends-local-businesses): A PromptRank study of 1,350 AI answers across ChatGPT, Claude, and Gemini, in 15 US cities and 3 industries.
