FREQUENTLY ASKED
How does the AI Prompt Tester work?
The AI Prompt Tester sends your brand name and URL to our backend, which uses Google Vertex AI (Gemini 1.5 Flash) to simulate how three major AI engines — ChatGPT, Claude, and Gemini — would respond to a user asking about your brand. Each simulation uses a distinct persona prompt to replicate each engine's distinct communication style.
Why do ChatGPT, Claude, and Gemini say different things about my brand?
Each AI model was trained on different datasets with different cutoff dates and applies different weighting to sources. ChatGPT relies on OpenAI's training corpus, Claude uses Anthropic's dataset with emphasis on nuance and safety, while Gemini leverages Google's Search index. Brand perception varies across all three based on which sources each model has indexed.
What should I do if AI models describe my brand inaccurately?
If AI engines misrepresent your brand, the fix requires Generative Engine Optimization (GEO). Specifically: (1) publish highly structured, fact-dense content about your brand on authoritative domains; (2) ensure your organization schema markup is implemented on your website; (3) build citations from sources that LLMs heavily weight, such as Wikipedia, Crunchbase, G2, and major press outlets.
How often should I test my AI brand perception?
We recommend testing monthly, since AI models are retrained and updated regularly. Major product launches, funding announcements, or brand pivots are also trigger events where testing AI perception is critical.
