Quick Verdict
You're comparing two completely different animals here. SpyFu is a 20-year-old competitive intelligence veteran that lives for exposing competitor PPC campaigns and organic keyword strategies. Amplitude AI Visibility is a product analytics platform that recently added features to track how AI-generated traffic behaves on your website.
The confusion makes sense — both tools claim to improve your digital marketing results. But SpyFu helps you spy on competitors before you build campaigns, while Amplitude helps you understand user behavior after they land on your site.

Feature Comparison
SpyFu's bread and butter is revealing what competitors spend on Google Ads, which keywords they bid on, and their organic ranking history going back 16 years. You can see exact ad copy variations, estimate monthly ad budgets down to the dollar, and discover profitable keywords your competitors rank for but you don't. Their Kombat feature literally shows you head-to-head keyword battles between you and specific competitors. Amplitude AI Visibility takes a completely different approach. It tracks how users arriving from AI search engines like ChatGPT, Perplexity, or Bing's Copilot interact with your website differently than traditional Google traffic. You can measure conversion rates by AI traffic source, identify which content AI engines favor when citing your site, and optimize user journeys specifically for AI-referred visitors. The overlap is minimal. SpyFu won't tell you how AI traffic converts on your site, and Amplitude won't reveal your competitor's keyword bidding strategies.
Pricing Comparison
Amplitude AI Visibility starts free with generous limits for smaller sites — up to 10 million events monthly costs nothing. Their paid tiers scale with usage, making it predictable for growing companies but potentially expensive for high-traffic sites. SpyFu costs $39 monthly for their Basic plan, which includes unlimited domain searches but limits you to 10,000 keyword searches and 10,000 ad history results per month. Most agencies quickly outgrow these limits and jump to the $79 Professional plan. There's no free tier beyond a limited trial, but you get immediate access to their full competitor database. For pure dollar efficiency, Amplitude wins if you're just starting out. But SpyFu's pricing reflects the value of their proprietary competitor data — information that took decades to collect and costs serious money to maintain.
Best For
SpyFu is the clear choice when you need to understand competitor strategies before launching campaigns. If you're in a competitive niche and want to see exactly which keywords drive your competitors' growth, their ad spend patterns, or historical ranking changes, SpyFu delivers data you can't get anywhere else. Agencies managing PPC campaigns particularly love the ad copy history and budget estimates. Amplitude AI Visibility makes sense when you're already getting meaningful traffic from AI sources and want to optimize for it. If you've noticed traffic spikes from Perplexity or ChatGPT but aren't sure how these visitors behave differently, Amplitude helps you measure and improve those user journeys.
The Verdict
Pick SpyFu if competitive intelligence drives your strategy. Pick Amplitude if understanding AI traffic behavior matters more than spying on competitors. Most serious SEO operations eventually need both — SpyFu for planning campaigns and Amplitude for optimizing results. But if you're choosing just one, SpyFu delivers more immediate competitive advantage unless AI traffic already represents a significant portion of your visits. Start with SpyFu's free trial and audit three competitors to see if the insights justify the monthly cost.
Our verdict
For features, spyfu leads. On a budget, go with amplitude-ai-visibility.
