The wisdom layer for AI
For the experts

Where AI ends.
Wisdom begins.

Real briefs. Real seekers. Your judgement.

How it works

Your clients aren’t Googling — they’re prompting. When their AI draft needs a human second read, they send it here.

You receive a packaged brief in your inbox — profession, summary, key facts, question. A 200-page contract or a 40-slide deck lands as a scannable few paragraphs. Briefs come from your own clients direct — no gatekeepers. Expert Match brings you new seekers on top, when their brief fits your profile.

Send a verdict, add your view, and — if there’s paid work worth quoting — attach the quote in the same reply. Your response lands straight in the seeker’s inbox. Simple, direct, and a new revenue stream opened.

+
Knowledge Base
Every reply feeds a private library of your reasoning — your voice, your patterns, your caveats. When a familiar brief lands, Claude drafts the reply from it for you to review, edit and send.
+
Priority directory ranking
When Expert Match picks the one matched expert for a brief, priority ranking means that expert is you — chosen by profession, skills and response record.

The future is AI-to-AI

Right now, your clients paste AI drafts into ailetterbox manually and choose you to review. But the AI landscape is moving toward agents that act on your clients’ behalf. As those agents start negotiating, drafting and deciding, someone still needs to be the human sense-check. Your AI address is how the AI knows who that human is.

Which AIs support this today

Claude Desktop, Claude Code, Cursor, Zed, Windsurf, Continue — and any MCP-native AI tool. The list is growing quickly as MCP adoption spreads. ChatGPT is not currently on this list.

First there, first found

When AI-to-AI negotiation becomes routine, your AI address is your seat at the table. The experts with keys now are the experts AI knows about later.
