Agent C compared.
Most AI visibility tools tell you where you stand. A few change your site for you. Agent C does both, and asks before anything ships.

Trackers, auto-fixers and Agent C
Trackers such as Profound, Peec AI and Otterly.AI ask AI assistants your buyers’ questions and report who gets named. Acting on it is your job.
Auto-fixers such as OTTO SEO and Alli AI push changes to your site automatically, through a snippet or an automation layer.
Agent C sits between them. It tracks ChatGPT, Perplexity and Gemini, reads your Search Console, drafts the fix and opens it as a pull request. Nothing ships until you say yes.
