AI Inbox

Every Expert AI account gets a personal MCP endpoint — your AI address at mcp.ailetterbox.com/your-name. Give it to any client and their AI chat — Claude, Cursor, Zed, Windsurf — can route briefs straight to your inbox and dashboard. As agentic AI reaches scale, this is how your clients’ AI finds the human it needs to check with.

Knowledge Base

Every reply you give feeds a private library of your reasoning — your patterns, your caveats. When a familiar brief lands, Claude drafts the reply for you using your own past reasoning. You review, edit, approve. Nothing goes out without you.

Community Letterbox

Share a branded letterbox with unlimited Expert Pro or Expert AI colleagues. Pool combined wisdom. You’re the admin: invite, remove, transfer admin. Your first invited Expert AI colleague takes 50% off your subscription.
