AI gatekeeper
A receiver-side, cost-gated, AI-mediated inbound channel for high-value attention. The gatekeeper sits in front of a person whose time is the scarce resource and decides — on the receiver's rules — what gets through.
An AI gatekeeper is a receiver-side inbound channel that sits in front of a high-value inbox and decides — on the receiver's rules — what gets through. It combines three things that have not been combined before:
- Receiver configuration. The person whose attention is at stake sets the rules: what they care about, what they don't, what threshold a pitch has to clear.
- Cost gating. Senders pay a real cost to pitch. The cost is the filter: low-effort spray-and-pray collapses, and serious senders surface themselves.
- AI screening. A model runs a structured intake, scores each pitch against the receiver's preferences, and routes the result. A human would never have time to do this manually.
It is not an inbox filter on top of free email. Filters sort messages that have already arrived in a free channel and treat the symptom; AI gatekeepers replace the channel and treat the cause.
It is also not a calendar tool, an intro broker, or a personal assistant. A calendar schedules meetings the receiver has already agreed to take. An intro broker forwards warm introductions. A PA reads everything to decide what to escalate. The AI gatekeeper combines the work of all three into a single, paid, AI-mediated front door — and refuses to be backwards- compatible with the channel it's replacing.
PitchGate is the canonical example today: one link on a receiver's profile that says "if you want to pitch me, use this — not my DMs."
