Write it the way a real buyer would phrase it inside ChatGPT — full sentence is fine.
Paste a context hint, topic or seed keyword. We model the addressable audience across LLM ad surfaces (ChatGPT, Gemini, Claude, Perplexity) using observed US search volume, intent classification, and benchmark CPCs from comparable paid channels. Outputs are directional — use them to size a test, not to forecast Q4.
