Questions about AI Sentiment.

AI Sentiment measures how AI models describe your brand when buyers ask about it: a positive, neutral and negative score for each model, an overall score, and the short phrases behind them, so you can see what shapes the tone.
AI models repeat what they find in reviews, forums, articles and your own site, so negative tone usually comes from recurring complaints or outdated information in those sources. AI Sentiment shows the phrases behind each score, so you can see what the models are picking up.
ChatGPT, Claude, Perplexity, Gemini and Google AI Overviews. It checks ChatGPT, Perplexity and Gemini by default; choose any subset or run all five.
No. AI Sentiment returns the scores and phrases, not the full text. Use AI Search when you want to read each model's complete answer and its sources.
$0.03 to $0.08 per AI model: $0.19 across the three default models or $0.30 across all five. You only pay when the check succeeds.
