Penumbra · Generative Engine Optimization
AI is talking about your brand right now. Do you know what it's saying?
ChatGPT, Gemini, Perplexity, and Grok already shape how customers discover your brand. Penumbra monitors, measures, and improves your visibility across every AI model — so you control the narrative before your competitors do.
Search is moving from Google to AI. Your analytics haven't caught up.
You can't optimize what you can't see
No analytics, no alerts, no way to know if AI recommends you or your competitor — or recommends neither.
Competitors are already mentioned
AI models cite whoever has the best content and citations — not necessarily the best product. Silence is the worst outcome.
Traditional SEO doesn't transfer
AI engines synthesize answers from multiple sources. Page 1 rankings don't guarantee AI visibility. This is a new discipline.
The first full-stack platform for Generative Engine Optimization.
Penumbra handles the monitoring, labeling, analytics, and recommendations — all in a single workspace built for marketing and brand teams.
