 ## The Problem
 
-How do you find more free AI model quotas?
-How do you connect free or paid quotas to the tools you're already using?
-How do you configure Claude Code, OpenCode, or any AI tool in one click?
+**Your AI subscriptions are locked in silos.**
 
-**OpenRelay solves all of this.**
+Claude Pro only works in Claude Desktop. Kiro quota only works in Kiro. Groq is free but you have to configure every tool manually. Cursor burned through your 500 requests and now you're stuck.
+
+**OpenRelay breaks the silos.**
+
+- Find more free AI quota (Groq, Cerebras, SambaNova, Gemini — all free, all auto-discovered)
+- Connect any quota to any tool you're already using
+- One-click configure Claude Code, OpenClaw, Aider, Goose, and more
