Lumen AIMeasure brand reputation in AI responses
A 0–100 score that captures the tone ChatGPT, Gemini, Claude, Perplexity, and more use when mentioning your brand. 100 = always positive, 0 = always negative, 50 = neutral.
Sentiment Analysis
Know exactly what AI thinks about your brand
Beyond whether you're mentioned, what matters is *how* AI talks about you. Lumen measures tone — positive, neutral, negative — with a 0–100 Sentiment Score. Detect reputation problems before they escalate, and celebrate when AI speaks positively about you.
Sentiment Analysis
What you get
Detect perception shifts early
If your Sentiment Score drops, something changed. It could be a negative review being cited, a competitor positioning you poorly, or a product issue.
Works alongside Visibility Score
You can have high visibility but low sentiment — you appear often but AI speaks negatively. Lumen shows both metrics together.
Weekly and monthly trends
Watch how perception evolves over time. Did it worsen after an event? Improve after a campaign? The chart proves it.
Sentiment Analysis
How it works
Tag prompts with "Sentiment" intent
When creating a prompt, mark it as "Sentiment" type so Lumen analyzes the tone of responses, not just mentions.
We run prompts daily
Each daily execution against ChatGPT, Gemini, Claude, Perplexity, and more includes sentiment analysis — positive, neutral, or negative.
