What it does

- Target-question design: extracts and prioritizes, by industry, region, and customer type, the questions in which a brand should appear.
- AI answer monitoring: repeatedly calls the same question across multiple LLMs to track where a brand is mentioned and recommended.
- AI-trainable content: produces content in formats that AI finds easy to cite, such as definitional sentences, FAQs, and comparison pages.
- External-channel distribution · multilingual: distributes a consistent definition across the external channels that AI references, and supports multilingual operation.
It has also been reported to hold a separate product, GenRank.
