Key takeaways
- Amplitude AI Visibility is free and bundled into every Amplitude plan, but it only tracks ChatGPT and Google AI Overview. Promptwatch tracks a much wider set: ChatGPT, Claude, Gemini, Perplexity, Grok, DeepSeek, Copilot, Mistral, Meta Llama, and both Google AI surfaces.
- Amplitude's real edge is native integration with Amplitude Analytics, Session Replay, and Web Experimentation, so you can tie an AI mention directly to a session, a conversion, and revenue without exporting anything. Promptwatch doesn't have that built-in product-analytics stack; it leans on GA4, Search Console, or its own visitor script.
- Promptwatch is the only one of the two that does anything with the data once it's collected: content gap analysis, AI-generated GEO articles published straight to your CMS, crawler log analysis, and a prioritized action list. Amplitude gives you recommendations, not execution.
- Amplitude's usage limits are prompt-based (500 to 5,000 depending on plan) and enabling AI Visibility eats into your Amplitude event quota, which matters if you're already close to your MTU ceiling. Promptwatch's limits are prompt- and site-based per plan, starting at 50 prompts on the $95-99/mo Essential tier.
- If you're already an Amplitude customer trying to get a directional read on AI visibility without spending anything, start there. If you need a dedicated GEO platform with crawler logs, Reddit/YouTube citation tracking, and content production, Promptwatch is built for that specifically and Amplitude explicitly says it isn't.
Overview
Promptwatch is a dedicated AI search visibility and GEO platform. It tracks prompts across a dozen-plus AI models and surfaces, shows you which of your pages get cited (and which don't), logs actual AI crawler visits to your server, and then does something most trackers don't: it generates and publishes GEO-optimized content to fix the gaps it finds. It's used by 1,840+ brands and agencies including Duolingo, Yelp, and Typeform, and sits at 4.7/5 on G2.
Amplitude AI Visibility is a feature inside Amplitude's broader analytics platform, not a standalone product. It gives you a visibility read across ChatGPT and Google AI Overview, a sentiment score, competitive rankings, and recommendations, all wrapped into whatever Amplitude plan you're already on (including the free tier). Its pitch is simple: instead of buying another dashboard, plug AI mentions into the analytics stack you already use to measure everything else.

Head-to-head feature deep-dive
Engine coverage
This isn't close. Amplitude tracks two surfaces: ChatGPT and Google AI Overview. That's a real gap if your customers are asking Claude or Perplexity about you, which a lot of B2B buyers are these days. Promptwatch tracks all of those plus Gemini, Grok, DeepSeek, Copilot, Mistral, and Meta Llama, and adds new models as they ship.
Verdict: Promptwatch, decisively, if breadth of engine coverage matters to you.
Product analytics integration
Here's where Amplitude actually wins something. Because AI Visibility lives inside Amplitude, an AI mention isn't just a data point sitting in a separate dashboard, it's connected to the same session data, funnels, and cohorts you already use for everything else. You can build a retargeting cohort of visitors who arrived from an AI citation without touching another tool. Promptwatch has its own visitor analytics and can pull from GA4 and Search Console, but it's not the same as living inside your core product analytics stack.
Verdict: Amplitude, if you're already deep in the Amplitude ecosystem and want AI visibility to slot into existing dashboards without new tooling.
Content and remediation
Monitoring is the easy part. The harder question is what happens once you see you're invisible for a prompt that matters. Promptwatch's Content Agents write and publish GEO-optimized articles directly to your CMS on a schedule, backed by content gap analysis that scores your existing pages against what AI models actually cite. Amplitude gives you
