# Gauge > The End-to-End AI Marketing Agent for AI Search (AEO/GEO) Gauge is an AI marketing assistant that helps growth marketers reach the audiences who now search with AI. Gauge measures what LLMs say about your brand, how they think, and what content they surface; analyzes the gaps; then generates content and publishes it directly to your site or CMS — owning the loop end to end: measure the inputs, create the content, publish, and measure whether it worked. Backed by Y Combinator (S24), Gauge covers answer engine optimization (AEO), generative engine optimization (GEO), large language model optimization (LLMO), and traditional SEO in one platform. Gauge's second product, Agent Led Growth, measures what coding agents recommend and how they build with your product. ## Markdown Versions Every page on this site is also served as clean markdown — same content, a few percent of the bytes. Ways to get it: - Append `.md` to the URL: https://www.withgauge.com/pricing.md, https://www.withgauge.com/index.md (the `index.html.md` form works too) - Send `Accept: text/markdown` to the normal URL — the markdown comes back at that same URL - Read `` in the page head - Read the `Link: <...>; rel="alternate"; type="text/markdown"` response header, which a HEAD request sees without downloading the page ## Article Indexes - [Blog index for LLMs](https://www.withgauge.com/blog/llms.txt): Every blog post — announcements, case studies, and guides — with dates and summaries - [Resources index for LLMs](https://www.withgauge.com/resources/llms.txt): Every educational resource and tool comparison, with dates and summaries ## Technical Documentation & API - [Gauge Documentation](https://docs.withgauge.com): Product and technical documentation - [Documentation Index for LLMs](https://docs.withgauge.com/llms.txt): Machine-readable index of all Gauge documentation - [Core AEO Metrics](https://docs.withgauge.com/introduction/core-aeo-metrics): Definitions of the core metrics Gauge tracks - [AI Engines Gauge Tracks](https://docs.withgauge.com/navigating/ai-engines): Supported answer engines and tracking coverage - [Rankings & Visibility](https://docs.withgauge.com/navigating/rankings-visibility): Visibility and competitive ranking methodology - [Prompts & Citations](https://docs.withgauge.com/navigating/prompts-citations): Prompt monitoring and source citation tracking - [Sentiment Analysis](https://docs.withgauge.com/navigating/sentiment-analysis): Sentiment methodology, themes, and model-level analysis - [Gauge MCP](https://docs.withgauge.com/help/mcp): OAuth-based Model Context Protocol integration for AI clients - [OpenAPI Specification](https://docs.withgauge.com/api-reference/openapi.json): Machine-readable Gauge API reference ## Metric Definitions - **Visibility**: The percentage of tracked AI answers that mention the brand: `(answers that mention the brand / all tracked answers) × 100`. Each answer is evaluated for whether the brand appears within the measured prompt, model, and date set. - **Citation rate**: The percentage of tracked AI answers that cite at least one URL on the brand's domain: `(answers citing the brand's domain / all tracked answers) × 100`. It measures source inclusion, not whether the brand name appears in the prose. - **Sentiment**: Gauge analyzes the actual answer text from every tracked prompt across every model and classifies the tone used to describe the brand as positive, neutral, or negative. It reports the distribution and trend of those classifications, model-level differences, and recurring themes supported by response excerpts. ## Supported AI Platforms - OpenAI ChatGPT - Google AI Overviews - Perplexity - Google Gemini - Google AI Mode - Microsoft Copilot - Anthropic Claude ## Main Pages - [Homepage](https://www.withgauge.com/index.md): Both Gauge products — AI visibility (Chat) and Agent Led Growth (Agents) - [Agent Led Growth](https://www.withgauge.com/agents.md): How coding agents pick tools, and how Gauge makes your product the one they choose - [Pricing](https://www.withgauge.com/pricing.md): Plans and pricing for the AI visibility product - [Agent Led Growth Pricing](https://www.withgauge.com/agents/pricing.md): Monthly credit plans for Agent Led Growth - [Blog](https://www.withgauge.com/blog.md): Insights on AI search and brand visibility - [Resources](https://www.withgauge.com/resources.md): Guides, tools, and educational content - [Team](https://www.withgauge.com/team.md): Meet the Gauge team - [Brand assets](https://www.withgauge.com/brand.md): Download Gauge logos, dog marks, app icons, and brand colors - [Wall of Love](https://www.withgauge.com/wall-of-love.md): What customers say about Gauge - [GEO](https://www.withgauge.com/geo.md): Generative Engine Optimization information - [AEO](https://www.withgauge.com/aeo.md): Answer Engine Optimization information - [LLMO](https://www.withgauge.com/llmo.md): Large Language Model Optimization information - [AI Visibility](https://www.withgauge.com/ai-visibility.md): What AI visibility is and how to improve it ## Features - [Know Exactly When and Where AI Talks About You](https://www.withgauge.com/features/prompt-tracking.md): Track prompts for your brand across ChatGPT, Gemini, Perplexity & Claude.
