# Welcome to Promptwatch

> Promptwatch measures how visible your brand is in AI answers from ChatGPT, Gemini, Perplexity, and other models, and turns AI search into a channel you can grow.

### What Promptwatch is

Promptwatch measures how AI answer engines talk about your brand. When someone asks ChatGPT for the best tool in your category, or Google's AI Overview answers a question your customers ask, your brand either shows up or it doesn't. Promptwatch tracks which one is happening, across models, markets, and time, and tells you what to do about it.

You define the questions that matter for your business, and Promptwatch asks them daily across the AI platforms you choose: ChatGPT, AI Overview, AI Mode, Copilot, Gemini, Perplexity, Grok, Claude, and more. Every answer is stored, analyzed, and turned into metrics you can act on.

### What GEO means

GEO, Generative Engine Optimization, is the practice of making your brand and content visible in AI-generated answers. It is the successor discipline to SEO, born from a real shift in behavior: a growing share of product research now happens inside a chat window instead of on a results page.

The shift changes the rules. A search results page shows ten links; an AI answer names two or three brands and moves on. There is no page two. Either the model mentions you, cites your content as a source, or you're invisible for that question. GEO is about earning those mentions and citations deliberately, and it is measurable, which is where Promptwatch comes in.

### How it works: three kinds of data

Promptwatch combines three data sources to give you the full picture:

* **AI responses**: your prompts run daily across the models you track, as a real user in your target market would ask them. From the answers, Promptwatch extracts [mentions and citations](/docs/academy/citations-vs-mentions), scores your [visibility](/docs/academy/visibility-score) and sentiment, and computes your [Share of Voice](/docs/academy/share-of-voice) against competitors. See [how Promptwatch collects data](/docs/academy/how-promptwatch-collects-data).
* **Crawler logs**: AI companies crawl your website with bots like GPTBot, ClaudeBot, and PerplexityBot. Promptwatch reads those visits from your CDN, so you can see what the models actually read on your site, and what they ignore.
* **AI visitor analytics**: when someone clicks through to your site from ChatGPT or Perplexity, Promptwatch records it. This is the human traffic your AI visibility produces, the bottom of the funnel.

Together they answer the three questions of GEO: what are AI models saying about you, what are they reading from you, and what traffic is it sending you?

### Who it's for

* **Marketing and SEO teams** who own organic growth and need AI search to be a measured channel instead of a blind spot.
* **Agencies** managing AI visibility for multiple clients, with a project per client.
* **Brands of any model**, B2B or D2C: if your customers research before buying, AI answers are already shaping that research.

You don't need to be technical. Setup is a guided flow, and the deeper integrations, crawler logs and analytics, come with step-by-step guides.
