Proofsource for Claude
Proofsource measures how AI assistants talk about your brand. It asks ChatGPT, Perplexity, Claude and Google AI Overviews the questions your buyers ask, and shows how often you are mentioned, which competitors are recommended instead, and which sources the answers cite.
This plugin connects Claude to your Proofsource workspace and adds two skills:
- ai-visibility-audit: a sourced summary of your AI visibility, competitors, cited sources and recent changes.
- fix-plan: a prioritized plan from your open gaps, plus tracking new buyer questions and shipped fixes (always asks first).
Install
/plugin marketplace add lcbasu/proofsource-plugins
/plugin install proofsource@proofsource-plugins
Then run /mcp, pick proofsource and sign in with your Proofsource account. Try: "Is my brand mentioned in ChatGPT answers?"
