A curated list of tools, platforms, and resources for AI Search, Generative Engine Optimization (GEO) and Answer Engine Optimization (AEO): getting your brand found, mentioned and cited by ChatGPT, Perplexity, Gemini, Google AI Overviews, Copilot and other AI answer engines.
Search is moving from "ten blue links" to direct AI answers. When someone asks an assistant for the best tool, product or provider, the model returns a short synthesized response with a handful of brands and citations. Showing up in those answers is a new discipline, variously called GEO (Generative Engine Optimization), AEO (Answer Engine Optimization) or AI SEO. This list collects the tools and knowledge to do it well.
