The Intelligence Platform for AI Brand Visibility·trysill.com

Sill is a B2B SaaS platform that monitors how AI engines such as ChatGPT, Gemini, Perplexity, Claude, Grok, and Google AI Overviews mention and recommend brands, measuring AI Share of Voice, sentiment, and citations.

The platform also includes a Watchdog feature that detects hallucinations and misinformation about a brand in AI responses.
