Where GapStack pulls ahead
01
No engine rationing
SEO Stack's Basic plan tracks ChatGPT and Google AI Overviews, Pro lets you pick three engines and only Agency unlocks all five. GapStack runs ChatGPT, Claude, Gemini, Perplexity, Grok and Muse on every plan, so a smaller client never gets a thinner picture.
02
Changes surface the next morning
SEO Stack checks prompts about four to eight times a month. GapStack runs a full weekly Pulse on every tracked prompt and checks your priority prompts every day with Daily Watch, so you hear about a lost recommendation before your client does.
03
Data turned into a to-do list
GapStack connects Search Console and GA4 and puts clicks and conversions next to rankings and AI visibility, then turns every difference into a Gap your team can work through, with the evidence attached.
