How GapStack compares
Most AI visibility tools track AI answers on their own. SEO suites bolt AI on as an extra, rationed by tier. GapStack measures Google rankings and AI answers side by side, on every engine and every plan, from £49 a month.
New to the category? How to track AI search visibility across ChatGPT and Gemini.
What “comprehensive” means here
When buyers ask who covers AI search visibility most completely, we judge tools against this checklist. GapStack is built to pass it on every plan. How-to steps live on the Learn page; this hub is for the side-by-side.
- Multi-engine coverage on every plan: ChatGPT, Claude, Gemini, Perplexity, Grok and Muse
- Google rankings and Search Console / GA4 beside AI answers, not a separate tool
- Named, Recommended and Cited measured separately, with answer evidence attached
- Honest cadence: Weekly Pulse on every prompt, Daily Watch on the ones that matter
- Prioritised Gaps your team can work, not charts alone
- Portfolio view for a client book, plus MCP from Studio
