An AI marketing agent that tracks how often your brand actually gets mentioned by ChatGPT, Claude, Gemini, and Perplexity when people ask AI for recommendations — the AI-search equivalent of tracking your Google ranking, for the growing share of searches

Description
A growing chunk of the research people used to do on Google now happens by just asking ChatGPT or Perplexity directly, and if an AI answer engine doesn't mention your brand when someone asks 'what's the best tool for X', you lose that customer without ever knowing it happened — traditional SEO tools that track Google rankings don't see any of this. Gauge is built to fill that blind spot: it watches how AI engines answer real prompts over time and shows you exactly where your brand shows up, where a competitor is winning instead, and where you're invisible entirely.
Gauge is a YC-backed AI marketing agent that unifies fragmented data sources (GA4, Google Search Console, keyword and prompt data) into a single system tracking brand visibility across generative AI answer engines — ChatGPT, Claude, Gemini, and Perplexity. Core capabilities include prompt tracking over time, brand coverage and gap analysis (where a brand is missing from AI answers versus where it currently appears), and competitive positioning. It's already used by marketing teams at YC companies including Supabase, PostHog, and Mux. Pricing: Growth tier at $599/month (600 daily prompts tracked across major models, plus 18 monthly content pieces from its content engine); Enterprise is custom-priced. Gauge cites typical customers seeing a 3-5x visibility uplift within the first month.
💬 Our review
The short version: Gauge is a serious, not-cheap tool for a marketing team that has concluded AI-answer-engine visibility is now a real revenue channel worth actively managing, not a nice-to-have — it's overkill if you're not yet convinced AI search visibility matters to your business.
At $599/month, Growth is priced like a mid-market marketing platform, not an indie tool, which fits its target customers (marketing teams at funded startups like Supabase and PostHog) rather than a solo founder testing the waters. The core value — actually measuring whether AI engines recommend you over a competitor, with prompt-level tracking over time — addresses a genuinely new blind spot that classic SEO tools like Semrush or Ahrefs (built around Google's index, not LLM outputs) simply don't cover yet. The honest caveat: this is a fast-moving, unregulated measurement space — AI models change their answers frequently and non-deterministically, so 'tracking' AI visibility is inherently noisier than tracking a stable Google ranking, and a claimed 3-5x uplift figure should be read as a marketing statistic rather than a guarantee for your specific market.
