mentions-check
Focused AI brand-visibility skill. Use only when the user explicitly asks whether a brand shows up in AI answers — its mention, rank, or citations for a specific question — not when a brand name merely appears in passing.
When to use this skill
DO use when the user asks:
- "Is HubSpot mentioned when people ask ChatGPT about CRMs?"
- "Does Perplexity cite Stripe for 'best payment API'?"
- "What rank does Notion get in AI answers for 'best note-taking app'?"
- "Show up in Google AI Overviews for 'project management software'?"
- "Which brands does ChatGPT name first for 'top observability tools'?"
Do NOT use when:
- A brand or query appears incidentally in context
- The user is discussing GEO/AI search abstractly without a specific brand + query to measure
- The user has not signaled they want a visibility check
Each call costs credits (from $0.02). When the intent is ambiguous, confirm the brand and query with the user before calling.
Tools
