Fourslash is an AI search optimization agency. We help businesses and brands improve how they are found and described when buyers use ChatGPT, Perplexity, Claude, Gemini and Google's AI Overviews and AI Mode for information and recommendations.
We start with the questions your buyers ask: what they need, which providers they compare and what they want to know before choosing one. We examine what AI tools say in response, which businesses they mention or recommend, which sources they cite and whether the information about your business is accurate.
Our work focuses on improving the information behind those answers. That can mean clarifying your services and the customers you serve, strengthening existing website content, correcting inconsistent company information and making supporting evidence easier to find and understand. Where an AI answer is inaccurate, we investigate the available sources and address errors in the information you control.
This work is often called generative engine optimization (GEO) or answer engine optimization (AEO). Fourslash approaches it as AI search optimization: helping buyers find and understand your business through AI-generated answers, rather than treating traditional search rankings as the whole picture.
We establish a recorded starting point, identify the gaps, agree on the work and provide changes or recommendations your team can act on. Follow-up checks use the same buyer questions so we can report what changed, what stayed the same and where uncertainty remains. We cannot guarantee a mention, recommendation or ranking from a third-party AI tool.
Published monthly agency plans range from around US$500 to US$5,000, with broader programmes costing more. The scope matters: checking visibility is different from improving content, implementing changes and measuring progress over time.
Fourslash is for businesses that want a clearer, more accurate presence in AI search and a practical understanding of what needs to improve.
