# Brandure > Brandure is an answer engine optimisation agency. We show businesses where they stand inside AI answers on ChatGPT, Claude, Perplexity, Gemini, Google and Copilot, then do the work to get them named. Brandure is an answer engine optimisation (AEO) agency. It measures where a brand appears in AI-generated answers across ChatGPT, Claude, Perplexity, Gemini, Google AI Overviews and Copilot, diagnoses why, and does the entity, content and third-party placement work that changes it. Each engine is reported separately, because the six disagree with each other materially. ## Pages - [Home](https://brandure.io/): what AEO is, why answer engines differ from search, the six-surface point, and the free visibility report request. - [Service](https://brandure.io/service): how an engagement runs — baseline, diagnosis, execution, re-measurement against a control set — and what a client receives at each stage. - [Research](https://brandure.io/research): index of published measurement. ## Research - [Ask three AI engines who's best in Dubai: the overlap is low, not zero](https://brandure.io/research/ai-engines-disagree-best-in-dubai) — Across seven Dubai categories, ChatGPT, Perplexity and Gemini named 147 businesses and 10 appeared on all three.
